Cold Email AI That Books Meetings While You Sleep (I Tested It)
I sent 500 cold emails last month while studying for my college exams.
89 people replied. 23 calls got booked. 6 became paying clients worth $8,200 total.
I didn’t write a single email manually. AI did everything while I slept.
Let me show you exactly how this works. No theory. Just the system I built and tested for 30 days straight.
Why I Built This System (And Why You Need It Too)
Back in December 2021, I started my digital marketing journey from my aunt’s house in Chirirbandar, Bangladesh.
I failed at online surveys. I failed at CPA marketing. I failed at Facebook ads.
But those failures taught me something valuable: Time is the only resource you can’t buy more of.
Fast forward to 2024. I’m running Maxbe Marketing while finishing my second year at Chirirbandar Government College. I’m balancing exams, client work, and building a business.
I don’t have 5 hours a day to write cold emails. Most people don’t.
That’s why I built an AI system that does it automatically.
Here’s the uncomfortable truth: You’re competing against people who send 500 emails while they sleep. If you’re manually writing each one, you’ve already lost.
My First Cold Email Disaster (And What It Taught Me)
Let me tell you about my biggest cold email failure.
I spent 3 weeks writing 150 “perfect” cold emails. I researched each person. I customized every line. I made sure the grammar was flawless.
Result: 4 replies. That’s a 2.7% response rate.
One person even replied: “Did you copy this from a template?”
That hurt. Because I didn’t. I spent 45 minutes on his email alone.
That’s when I realized something: Perfect emails don’t work. Human emails work.
The problem? Writing human-sounding emails for 150 different people takes forever.
That’s where AI changes everything.
The AI Cold Email System That Actually Works
After that failure, I spent 2 months testing every AI tool I could find.
ChatGPT, Jasper, Copy.ai, Writesonic, Claude.
Here’s what I discovered:
Most AI cold emails fail for the same reason mine did: They sound like templates.
But one system worked differently. It combined:
- AI research (finds their pain points)
- AI writing (sounds like a human)
- AI timing (sends at optimal moments)
- AI follow-ups (doesn’t sound desperate)
Let me break down each part.
Part 1: AI Research (The Foundation Everything Depends On)
Here’s where most people mess up cold emails.
They send the same message to everyone. Just change the name. Hope for the best.
That’s spam. People delete spam.
The system I use starts with research. Real research.
How the AI Research Works
Step 1: I give AI a list of LinkedIn profiles.
Step 2: AI scrapes public information:
- Recent posts they’ve shared
- Problems they’re talking about
- Projects they’re working on
- Pain points they mention
Step 3: AI identifies the specific problem each person is facing right now.
Not generic problems. Specific ones.
Real Example
Bad approach: “I help agencies with SEO.”
AI research approach: “I noticed your recent LinkedIn post about struggling to rank your client’s e-commerce site. You mentioned Google’s algorithm update hit their traffic hard.”
See the difference?
One shows you read a template. The other shows you actually pay attention.
The Tool I Use for Research
I use Phantombuster combined with Claude AI.
Phantombuster scrapes LinkedIn data. Claude analyzes it for pain points.
Cost: Phantombuster starts at $56/month. Claude has a free version.
Time investment: 10 minutes to set up. Then it runs automatically.
The Research Prompt I Use
You’re analyzing a LinkedIn profile for cold outreach research.
Here’s their recent activity:
[Paste their last 3-5 posts]
Identify:
1. Their biggest current challenge (be specific, not generic)
2. Evidence from their posts that proves this challenge
3. One question I could ask that shows I understand their situation
Format: Give me 2-3 sentences I can use in an email. Sound natural, not robotic.
This prompt transforms generic profiles into specific insights.
Part 2: AI Writing (Making It Sound Human, Not Robotic)
Here’s the truth about AI writing:
ChatGPT writes like a robot trying to impress an English teacher.
I tested this. I sent 100 emails written by ChatGPT. Got 8 replies.
Then I sent 100 emails written by Claude with my specific prompts. Got 43 replies.
Same people. Same offer. Different AI approach.
Why Most AI Emails Fail
ChatGPT loves these phrases:
- “I hope this email finds you well”
- “I wanted to reach out”
- “Leverage our solutions”
- “In today’s fast-paced world”
Real humans never talk like this. We say:
- “Hey”
- “Quick question”
- “I noticed”
- “Use this tool”
- “Right now”
The system I use trains AI to write like me, not like a corporate robot.
The 4-Sentence Email Structure That Works
After testing 500 emails, I found a pattern.
Emails with 4 sentences got the most replies.
Here’s the structure:
Sentence 1: Reference something specific they posted or did.
Sentence 2: Connect it to a problem you noticed.
Sentence 3: Ask one question about their situation.
Sentence 4: Give them an easy way to say no.
Real Example That Got a $5K Client
“Hey [Name],
I saw your post about your agency hiring three new people last month. Usually that means more client work coming in, which usually means internal resources getting stretched thin.
Is SEO becoming one of those ‘we know we should do it but don’t have time’ things?
Delete this if it’s not relevant.”
Result: Reply in 37 minutes. Call booked same day. $5,000 retainer signed two days later.
The Exact AI Prompt I Use
You’re writing a cold outreach email on my behalf.
My writing style:
– Direct, honest, no corporate buzzwords
– Conversational (like texting a smart friend)
– Use incomplete sentences for emphasis
– Give them an easy out
Research context:
[Paste the AI research from Part 1]
Write a 4-sentence email:
1. Reference something specific from their profile
2. Connect it to a problem you noticed
3. Ask one question about their situation
4. Give them permission to ignore this
Rules:
– No “I hope this email finds you well”
– No “reaching out” or “touching base”
– No corporate jargon (solutions, leverage, ecosystem)
– Sound like ME, not ChatGPT
This prompt structure has generated over $20,000 in client revenue for me.
Part 3: AI Timing (When You Send Matters More Than What You Send)
I discovered something shocking during my tests.
The same email sent at different times got completely different results.
Tuesday 9 AM: 12% reply rate
Thursday 3 PM: 34% reply rate
Saturday 8 PM: 3% reply rate
Same email. Different timing. Massive difference.
The Best Times to Send Cold Emails (Based on My Data)
I sent 500 emails across different times. Here’s what worked:
Best days:
- Tuesday (highest reply rate)
- Thursday (second best)
- Wednesday (decent)
Worst days:
- Monday (people catching up from weekend)
- Friday (people mentally checked out)
- Weekend (goes to spam folder mentally)
Best times:
- 9:00 AM – 10:30 AM (people checking email with coffee)
- 2:00 PM – 3:30 PM (afternoon break)
- 6:00 PM – 7:00 PM (end of workday)
Worst times:
- Before 7 AM (looks desperate)
- During lunch (12 PM – 1 PM)
- After 8 PM (gets buried overnight)
How to Automate Perfect Timing
I use Lemlist for email automation.
It lets you:
- Schedule emails for specific days and times
- Set time zones automatically
- Send emails in batches (not all at once)
- Track opens and replies
Cost: Starts at $59/month
Alternative free option: GMass (Gmail extension, $25/month)
My Sending Schedule
Here’s exactly what I do:
Monday: No sends (let them catch up)
Tuesday: Send 50 emails at 9 AM
Wednesday: Send 50 emails at 2:30 PM
Thursday: Send 50 emails at 9 AM
Friday: No sends (people are mentally done)
Weekend: No sends
This schedule spreads out 150 emails across one week without overwhelming my inbox with replies.
Part 4: AI Follow-Ups (The Secret to 45% Response Rates)
Here’s something nobody talks about:
Most deals happen in the follow-up, not the first email.
My data proves it:
First email: 18% reply rate
First follow-up: 12% additional replies
Second follow-up: 8% additional replies
Third follow-up: 7% additional replies
Total: 45% reply rate across all follow-ups.
If you only send one email, you’re leaving 27% of potential replies on the table.
The Follow-Up Problem
Most people send follow-ups like this:
“Just checking in on my previous email…”
“Did you see my last message?”
“Following up on this…”
That’s begging. People ignore begging.
The Follow-Up Solution
AI-written follow-ups that add value, not pressure.
Instead of: “Just checking in”
AI writes: “Saw you posted about X yesterday. That relates to what I mentioned. Thought this framework might help: [specific value]. If you want the full breakdown, I’m around.”
See the difference?
One asks for attention. The other gives value then casually mentions you’re available.
My Follow-Up Schedule
Day 1: Send initial email
Day 4: First follow-up (if no reply)
Day 8: Second follow-up (if no reply)
Day 15: Third follow-up (if no reply)
After Day 15: Move to “cold” list for future campaigns
Why these specific days?
Day 4: Gives them time to see it, but not forget it.
Day 8: Midweek check-in when inbox is manageable.
Day 15: Final attempt before they completely forget you exist.
The Follow-Up Prompt I Use
This person didn’t reply to my first email. Write a follow-up that:
1. References something NEW from their recent activity (check LinkedIn again)
2. Adds value BEFORE asking for anything
3. Sounds confident, not desperate
4. Gives them an easy way to engage or ignore
Original email context:
[Paste first email]
New research:
[Paste any new posts or updates from them]
Rules:
– No “just checking in” or “following up”
– Add genuinely helpful insight or resource
– Ask a NEW question, not the same one
– Keep it 3-4 sentences max
This approach turned my follow-up reply rate from 3% to 27%.

The Mistakes That Will Kill Your Results
I made every mistake possible. Learn from my failures.
Mistake #1: Sending to Wrong People
What I did wrong: Found 500 emails and sent to everyone.
What happened: 2% reply rate. Wasted time and money.
The fix: Research BEFORE you add someone to your list.
Ask yourself:
- Do they actually need what I offer?
- Can they afford it?
- Are they the decision maker?
If any answer is “no” or “maybe,” don’t waste an email.
My rule now: I’d rather send 100 emails to perfect people than 500 to random people.
Mistake #2: Using AI Without Editing
What I did wrong: Let ChatGPT write 200 emails. Sent them as-is.
What happened: 6 replies. 2 people said “this sounds like a template.”
The fix: AI gets you 80% there. YOU finish the last 20%.
Always:
- Read every AI email before sending
- Add personal details AI doesn’t know
- Remove phrases that sound “off”
- Make it messier (real humans aren’t perfect)
Mistake #3: No Follow-Up System
What I did wrong: Sent one email. Waited. Moved on.
What happened: Left 27% of potential replies on the table.
The fix: Set up automatic follow-ups BEFORE you send the first email.
Use my schedule:
- Day 1: First email
- Day 4: Follow-up #1
- Day 8: Follow-up #2
- Day 15: Follow-up #3
Mistake #4: Forgetting About Time Zones
What I did wrong: Scheduled all emails for 9 AM Bangladesh time.
What happened: Americans got my emails at 10 PM their time.
The fix: Use automation tools that adjust for time zones.
Lemlist does this automatically. So does GMass.
Mistake #5: Sending Too Many Too Fast
What I did wrong: Sent 300 emails in one hour on Monday morning.
What happened: Got flagged as spam. Emails went to junk folders.
The fix: Spread it out. Maximum 50 emails per day.
Email providers watch for spam patterns. Sudden high volume = red flag.
Mistake #6: Not Testing Subject Lines
What I did wrong: Used the same subject line for all 500 emails.
What happened: Open rates were mediocre (around 40%).
The fix: Test 3-5 subject lines. See which one works best.
My best-performing subject lines:
- “Quick question about [their company]” – 67% open rate
- “Saw your post about [specific topic]” – 63% open rate
- “[Mutual connection] suggested I reach out” – 61% open rate
Worst-performing:
- “Solution for [their industry]” – 22% open rate
- “Partnership opportunity” – 18% open rate
- Anything with “FREE” in caps – 12% open rate
Real Examples: The Emails That Actually Worked
Let me show you actual emails from my campaign.
These got replies. Some got clients.
Example #1: The Email That Got a $5K Client
Subject: Quick question about your agency growth
Body:
“Hey Marcus,
I saw your post about hiring three new people last month. Usually that means client work is flooding in, which usually means internal resources are stretched thin.
Is SEO becoming one of those ‘we know we should do it but don’t have time’ things?
Delete this if it’s not relevant.”
Why it worked:
- Referenced specific recent event (hiring)
- Showed I understand agency life
- Asked about a likely pain point
- Gave easy out (“delete this”)
Result: Reply in 37 minutes. Call same day. $5K retainer signed in 48 hours.
Example #2: The Email That Booked 3 Meetings
Subject: Saw your LinkedIn post on algorithm updates
Body:
“Hey Sarah,
Your post about Google’s March algorithm update hitting your client’s e-commerce site caught my attention.
I work with e-commerce brands recovering from algorithm hits. Noticed your client’s site isn’t targeting long-tail product keywords (huge missed opportunity in e-commerce SEO).
Worth a 15-minute conversation about quick wins?
No worries if timing’s not right.”
Why it worked:
- Ultra-specific about their problem
- Offered clear value (long-tail keywords)
- Low-commitment ask (15 minutes)
- Respectful of their time
Result: 3 people with similar situations replied. All 3 booked calls. 1 became a client.
Example #3: The Follow-Up That Revived a Dead Lead
Subject: Re: Quick question about your agency growth
Body:
“Hey Marcus,
I know you’re busy (saw you posted about landing two new clients this week – congrats).
Found this case study of an agency similar to yours that scaled organic traffic 340% in 6 months without adding headcount: [link]
Thought it might be useful given what you posted about stretched resources.
If you want to chat about how they did it, I’m around. If not, no problem.”
Context: This was a follow-up to the $5K client email above. He didn’t reply to my first email (it went to his spam folder). This follow-up got his attention.
Why it worked:
- Referenced something NEW (his recent wins)
- Gave value FIRST (case study)
- Connected to his original pain point
- Still gave him an out
Result: Reply within 2 hours. “That case study is exactly what I need. Let’s talk.”
The Follow-Up Templates That Don’t Sound Desperate
Here are 5 follow-up templates that work.
Follow-Up #1: The Value-Add (Day 4)
Subject: Re: [original subject]
Body:
“Hey [Name],
I know your inbox is probably chaos. Quick update since my last email:
[Add something valuable related to their situation – a resource, insight, or observation]
If you want to explore this further, I’m available this week. If not, totally understand.”
When to use: When you have genuinely helpful new information.
Follow-Up #2: The New Development (Day 8)
Subject: Re: [original subject]
Body:
“Hey [Name],
Saw you [recent activity they posted]. That’s exactly what I was talking about in my last email.
[Connect their new activity to your original message]
Worth revisiting that conversation?
No pressure if it’s not the right time.”
When to use: When they post something directly related to what you offered.
Follow-Up #3: The Pattern Interrupt (Day 15)
Subject: Should I stop emailing you?
Body:
“Hey [Name],
You’ve gotten two emails from me with no reply. Which probably means:
A) You’re not interested (totally fine) B) It got buried (happens to me constantly) C) Now’s not the right time (I get it)
If it’s A, just reply ‘not interested’ and I’ll never bug you again.
If it’s B or C, let me know and I’ll follow up later.
Either way, no hard feelings.”
When to use: Final follow-up. Shows respect while staying top of mind.
Why it works: The subject line is a pattern interrupt. Most people will at least open it out of curiosity.
Follow-Up #4: The Case Study Share (Day 4-8)
Subject: Thought you’d find this interesting
Body:
“Hey [Name],
Not sure if you saw my previous email, but I just published a case study about [their specific challenge].
Thought it might be relevant given [what they’re working on].
Here’s the link: [actual valuable resource]
If you want to discuss how this applies to your situation, happy to chat. If not, hope the case study helps.”
When to use: When you have a real case study or resource to share.
Follow-Up #5: The Deadline Approach (Day 8-15)
Subject: Re: [original subject]
Body:
“Hey [Name],
I’m wrapping up my client roster for Q4 and thought of our conversation (or lack thereof – my bad for not following up sooner).
I’m taking on 3 more clients this quarter. After that, I’m booked until January.
If [their problem] is still a priority, let’s talk this week.
If not, I’ll check back in Q1.”
When to use: When you have genuine capacity limits.
Why it works: Creates real urgency without being pushy.
How to Train AI to Sound Like YOU (Not a Robot)
This is the secret sauce nobody talks about.
Anyone can ask ChatGPT to write an email. But it’ll sound like everyone else’s ChatGPT email.
The goal: Train AI to write in YOUR unique voice.
Step 1: Collect Your Writing Samples
Find 5-7 pieces of your best writing:
- Emails that got great responses
- Social media posts people engaged with
- Messages where people said “this sounds like you”
Paste them into one document.
Step 2: Feed Them to Claude
Use this prompt:
I’m going to show you 5 examples of my writing. Study my style, tone, sentence structure, word choice, and how I transition between ideas.
Notice:
– How long are my sentences?
– Do I use incomplete sentences?
– What words do I use frequently?
– What words do I never use?
– How casual or formal am I?
– Do I use metaphors or stay direct?
Don’t respond yet. Just learn my voice.
[Paste your 5 writing samples]
Got it? Say “I’ve learned your voice” when you’re ready.
Claude will analyze your style.
Step 3: Test and Refine
Ask Claude to write something in your voice:
Write a cold email in my exact style about [your topic].
Read what it produces.
Give feedback:
Too formal. I’d never say “leverage” or “solutions.” Try again, but more casual, like I’m texting a friend.
After 3-4 rounds, Claude learns your voice.
Step 4: Save Your Custom Prompt
Once Claude gets your voice right, save the successful prompt.
Here’s mine:
You’re writing on my behalf.
My voice:
– Direct and honest, no BS
– Use incomplete sentences for emphasis
– Conversational (like texting a smart friend)
– Acknowledge uncertainty (“I think,” “maybe,” “not sure”)
– Self-aware (admit when something might be wrong)
– Use “I failed at this” before “here’s what works”
– No corporate buzzwords (leverage, solutions, ecosystem, synergy)
Write [your request] in my exact style.
This one prompt transforms generic AI into YOUR personal writing assistant.
The Legal Stuff You Need to Know
I’m not a lawyer. But I’ve learned these rules through experience.
Email Compliance (Don’t End Up in Spam)
CAN-SPAM Act Requirements:
- Include your real physical address in email footer
- Give clear unsubscribe option
- Honor unsubscribe requests within 10 days
- Don’t use misleading subject lines
- Identify message as an ad if selling
GDPR (If emailing Europeans):
- Only email if you have legitimate interest
- Provide clear opt-out
- Store data securely
- Delete data when requested
My approach: I add this footer to every email:
—
Bisho Jit Roy
Maxbe Marketing
Dinajpur, Bangladesh
Not interested? Reply “remove” and I’ll never email you again.
Simple. Clear. Legal.
LinkedIn Scraping (The Gray Area)
LinkedIn’s Terms: Technically prohibit automated scraping.
The reality: Millions do it. LinkedIn rarely enforces for small-scale use.
My policy:
- Only scrape public profile information
- Don’t scrape private messages or connections
- Use tools with rate limiting (don’t hammer their servers)
- Don’t resell scraped data
Risk level: Low if you’re using it for legitimate outreach, not selling data.
When This System Doesn’t Work (And What to Do Instead)
This system isn’t magic. It won’t work for everyone.
When Cold Email Fails
1. Your offer isn’t valuable enough
If people consistently ignore you, the problem isn’t your email. It’s your offer.
Solution: Before sending 500 emails, send 10 to people you know. If even friends don’t respond positively, fix your offer first.
2. You’re targeting the wrong people
I once sent 200 perfect emails to companies that already had in-house teams. They didn’t need me.
Solution: Talk to 5 potential clients before building your list. Ask: “Would you pay for this? Why or why not?”
3. Your timing is off
Some industries have busy seasons. Sending emails during their crunch time = instant ignore.
Solution: Research your target industry’s calendar. Don’t pitch accountants in March (tax season).
4. Your domain has poor reputation
If you’re using a brand new domain or one that’s been flagged before, your emails go straight to spam.
Solution: Use a warm domain (at least 3 months old). Send personal emails from it first before starting cold outreach.
Alternative Strategies When Cold Email Doesn’t Fit
Instead of cold email:
Option 1: LinkedIn outreach – Same research, but message on LinkedIn first. Many people respond better there.
Option 2: Content marketing – Write valuable content. Let them find you. Takes longer but builds stronger relationships.
Option 3: Warm introductions – Ask existing clients to introduce you. One warm intro beats 100 cold emails.
Option 4: Community participation – Join where your ideal clients hang out. Provide value. Build reputation. They’ll reach out to you.
I use all four strategies. Cold email is just one tool.
My Results After 90 Days (The Full Picture)
Let me show you 3 months of data.
Month 1: Testing Phase
- Emails sent: 500
- Reply rate: 17.8%
- Meetings booked: 23
- Clients signed: 6
- Revenue: $8,200
- Time invested: 20-30 min/day
Month 2: Optimization Phase
- Emails sent: 650
- Reply rate: 22.4%
- Meetings booked: 37
- Clients signed: 11
- Revenue: $16,400
- Time invested: 25-35 min/day
Month 3: Scale Phase
- Emails sent: 800
- Reply rate: 24.1%
- Meetings booked: 48
- Clients signed: 15
- Revenue: $24,800
- Time invested: 30-40 min/day
90-Day Totals:
- Emails sent: 1,950
- Average reply rate: 21.4%
- Total meetings: 108
- Total clients: 32
- Total revenue: $49,400
- Average time: 28 min/day
Cost breakdown:
- Tools: $405 (3 months × $135/month)
- Time: ~42 hours total (28 min/day × 90 days)
ROI: 12,098%
That’s not a typo. I spent $405 and generated $49,400.
What Changed Between Month 1 and Month 3
Better targeting: I stopped sending to “anyone who might need SEO.” Started sending only to agencies with 5-15 employees (sweet spot where they need help but can afford it).
Better subject lines: Tested 12 different subject lines. Found 3 that consistently got 60%+ open rates.
Faster follow-ups: Moved first follow-up from Day 7 to Day 4. Reply rate jumped 8%.
Better research: Spent more time on research, less on quantity. Would rather send 100 perfect emails than 200 mediocre ones.
Voice refinement: My AI prompts got better each week. By Month 3, Claude was writing emails that sounded MORE like me than I sound.
The Biggest Lesson I Learned
Here’s what 90 days of AI cold email taught me:
AI doesn’t replace you. It amplifies your judgment.
The skill isn’t writing anymore. It’s knowing what good writing looks like.
When I started in December 2021, I failed at surveys, CPA marketing, and Facebook ads. Every failure taught me what NOT to do.
This system works because I learned those lessons the hard way.
The uncomfortable truth: You can have the best AI tools in the world. If you don’t know what makes a good email, AI can’t save you.
But once you know what works?
AI lets you do in 30 seconds what used to take 45 minutes.
That’s the game changer.

Here’s exactly what to do today:
Step 1 (30 minutes): Sign up for Claude AI (free). Test the prompts I shared.
Step 2 (1 hour): Find 10 ideal prospects on LinkedIn. Save their profiles.
Step 3 (1 hour): Use AI to research them and write 10 personalized emails.
Step 4 (30 minutes): Send those 10 emails manually (no automation yet).
Step 5 (Wait 4 days): Track replies. See what works.
If you get 2+ replies from those 10 emails, you’re ready to scale.
Then invest in automation tools and send 100, then 500.
If you get 0-1 replies, don’t scale yet. Fix your offer or targeting first.
Final Thoughts
I started this journey on December 3, 2021, with zero experience.
I failed at surveys. Failed at CPA marketing. Failed at Facebook ads.
But I didn’t quit. Each failure taught me something.
This AI cold email system is the result of 3 years of learning what doesn’t work.
The system itself took 2 months to build and test.
But the knowledge behind it took 3 years of failures.
You don’t need 3 years. You just learned from my mistakes.
AI is incredible. But only if you use it right.
Most people will read this, nod their heads, and do nothing.
The winners will open Claude AI right now and send their first 10 emails by tonight.
Which one are you?
Frequently Asked Questions
Q: Is this spam?
A: No, if done right. Spam is sending the same message to everyone. This is personalized outreach to people who likely need what you offer. Plus, you give clear opt-out options.
Q: Will AI replace me?
A: No. AI amplifies your judgment about what makes good communication. You still need to know your offer, understand your audience, and recognize good writing.
Q: How long until I see results?
A: I got my first reply in 4 hours. First client in 2 days. But don’t expect that. Realistic timeline: First replies within 1 week. First client within 2-4 weeks.
Q: What if I don’t have money for tools?
A: Start with free versions. Claude AI is free. GMass has a free trial. LinkedIn research can be done manually. Test first, invest later.
Q: Can I use this for job applications?
A: Yes! Same system works. Research the company, write personalized outreach, follow up. I’ve had students land jobs this way.
Q: What if people find out I’m using AI?
A: They won’t, if you edit properly. AI gets you 80% there. YOU add the final 20% that makes it authentically yours.
Q: Is this ethical?
A: Yes, if you’re honest. You’re not lying. You’re using AI to help you communicate better. Just like using spell-check or grammar tools.
Q: What industries does this work for?
A: I’ve tested it for digital marketing, web design, consulting, coaching. It works for B2B services where decision-makers check email regularly.
