Reply rate is one of the most important email marketing KPIs. It shows how many people actually respond to your message, whether you're trying to generate leads, book meetings, or even land a job.
But getting a reply isn’t always easy. Most emails get opened, maybe skimmed, and then forgotten. That’s a huge lost opportunity.
In this article, we’ll show you how to increase your reply rate with ChatGPT and MailTracker, two free tools that help you write better follow-ups, send them at the right time, and turn more messages into real conversations.
TL;DR: How to Increase Reply Rate?
- With ChatGPT, you can create personalized email follow-ups in seconds. No writing blocks, no time wasted.
- With MailTracker, you see exactly who opened your email, when, and how many times, so you know who’s interested and when to follow up.
- Together, they help you 3X your email reply rate, book more meetings, and start real conversations that lead to action.
What Is Reply Rate and Why It Matters
Your reply rate tells you how many people actually hit “reply” to your email. It’s not just about getting noticed, it’s about starting a conversation.
If you’re in sales, marketing, running your own business, or applying for a job, a high reply rate means more leads, more meetings, and more real interest in what you offer.
Unlike open rates, which only show if someone saw your email, reply rates show they were interested enough to respond. That’s the first real step toward closing a deal, booking a call, or building a connection.
If your reply rate is low, it’s a sign your emails aren’t hitting the mark, maybe the message isn’t relevant, or your timing is off.
The good news? Both are easy to fix.
Below, we’ll show you how to use ChatGPT to write emails that feel personal and clear, and how to use MailTracker to send those emails when they’re most likely to get a reply.
How to Use ChatGPT to Write Better Follow-Up Emails
Writing good follow-ups can be hard, especially when you’re reaching out to lots of prospects or don’t have time to write something personal every time.
That’s where ChatGPT comes in.
With the right prompt, ChatGPT can help you create personalized, relevant follow-ups in seconds.
You can tell who you're writing to, what your company offers, and how the person engaged with your first email.
Here's a simple prompt on ChatGPT asking about follow-up email ideas:
Here’s what you can do with ChatGPT:
- Adjust tone and word count depending on who you're contacting
- Reference the recipient’s pain points or previous interest
- Save time by generating multiple versions quickly
You’re not guessing anymore, you’re using context to make each follow-up feel like it was written just for that one person.
And the best part? You don’t need to be a writer. Just give ChatGPT the context, and let it help you craft messages that actually get an answer.
How to Use MailTracker to Track and Time Your Follow-Ups
You’ve sent a great email and now what? This is where MailTracker helps.
MailTracker shows you exactly what happens after you hit "send." You get real-time insights into how your prospects interact with your email:
- Did they open it?
- How many times?
- If your email was unopened
- If they clicked your links and more
Here's how a MailTracker notification looks when someone reads your email:
These small details make a big difference. If someone opened your email once, maybe they were just curious. But if they opened it 10 times in a week, that’s clear interest, and a signal to follow up right away.
With MailTracker, you're not guessing. You have data to guide your next move. That means you can:
- Follow up at the right time (not too soon, not too late) Here are the best times to send emails in 2025.

And it’s all super easy to use, with no complicated setup, and no clunky systems. Just install it once, and you're ready to start tracking.

Step 1: Write Your First Email with ChatGPT
Use ChatGPT to write a message that feels relevant and human.

Step 3: Create a Follow-Up Based on Behavior
Now you go back to ChatGPT, but smarter this time. Use what MailTracker tells you to guide your follow-up:
- No opens? Ask ChatGPT for a short, attention-grabbing follow-up.
- Opened once? Write a reminder that adds more context or value.
- Opened 10+ times? Clearly, they’re interested. Follow up directly and ask to book a meeting.
Here’s a prompt example:
You’re writing less, but saying more, because your follow-up is based on real interest, not random timing.
