5 Questions to Ask Claude About Your Email Opens

The mailcheck connector lets Claude, or any AI agent that supports MCP, read your tracking data and answer in plain language. Here are five questions worth asking every week, and what each one is good for.

Table of contents

1. Who has not opened my emails this week?

The fastest way to build a resend list. Claude lists the emails sent in the last days that were never opened, with the recipient and the subject.

2. Which prospects opened my emails several times?

Repeated opens are the strongest signal of interest. Ask for the recipients with the most opens in the last two weeks, and start your follow-ups there.

3. How engaged is this contact?

Before a call, ask how a given person has engaged with your emails: how many they received, how many they opened, and when they last opened one.

4. When was this proposal opened?

Ask about a specific email by its subject. Claude gives you every open, with dates and times, so you can see whether it is being read again.

5. How are my emails performing overall?

Open rate, average delay before the first open, number of emails tracked: a quick weekly overview without opening a dashboard.

Setting it up

The connector is available to subscribers at mcp.getmailcheck.com. The step by step setup is in asking Claude about your email opens, and the details are on the MCP page.

Conclusion

The data was already there; asking in plain language just makes it faster to use. Five questions, five minutes, and you know where to spend your follow-up time.
