01Opens
Know the moment it is opened
An invisible pixel, switched on email by email. Every open is logged to the second, and your own opens never count.
Chrome extension for Gmail, Outlook, Zoho Mail and more Email tracking that tells you
Email tracking that tells you
when to follow up.
See the second your email is opened and which link gets clicked, in every inbox you use. Claude or ChatGPT answer your questions through MCP.

Opens send you the signal. Your AI tells you what to do with it.
mailcheck catches every open in Gmail, Zoho Mail, Hostinger and Outlook, then hands the full history to your AI, Claude or ChatGPT. Ask in plain language and get the name to call.
MCPConnect it in three clicks from your AI, through OAuth. Read-only: it sees when your emails were opened, never what they say.
Opens in Gmail, Zoho Mail, Hostinger and Outlook reach mailcheck, which lists them live. Claude or ChatGPT reads them when you ask.
Claude mailcheck · recipient_engagement Who should I follow up with today?
Sarah reopened your proposal 4 times this morning, after 6 days of silence. Call her today.
- Step 1
Write your email as usual
In Gmail, Outlook, Zoho Mail, Hostinger, Orange or SFR, on the web. Nothing changes in your workflow, and no other tool to open.
- Step 2
Flip the tracking toggle
A "Tracking ON / OFF" button sits next to Send. You decide email by email, not once for everything.
- Day 3
Then, silence.
Day after day, no reply. Was it even read? Without a signal, you are left guessing.
- Step 3
Get notified on the first open
A browser notification the moment it happens, then the full history in your dashboard: who, when, how many times.
One extension, four superpowers
Everything that happens after you hit Send.
02Clicks
See which link they clicked
Turn on Clicks and every link is followed: which one, how many times, when. A pricing page clicked twice says more than a reply.
03Alerts
Right where you work
A browser notification on every open, and a check mark next to each tracked email in your Sent folder: grey when sent, green once read.
04History
The full story of every email
Every open and every click in one dashboard, across all your sender addresses. Filter it, then export it to CSV in one click.
Who it is for
For everyone who is waiting on a reply.
Sales
Call while the proposal is still open on their screen, not three days later.
Freelancers and agencies
Know the quote was read before you chase the invoice, and which link they went to see.
Founders and recruiters
Follow up at the right moment, while your email is still on their mind.
Works where you already are
Six webmails. Twenty languages. One extension.
Gmail, Zoho Mail, Outlook, Hostinger, Orange and SFR, on the web. The extension, the dashboard and the alerts speak your language.

Built for trust
Tracking you can explain to anyone.
-
Your own opens never count
Re-reading your own sent email is filtered out, and opens in the first seconds after sending are ignored.
-
One switch per email
Tracking and clicks are decided email by email, right next to Send.
-
AI only when you say so
Tracking never reads the content of your emails, and neither does the MCP connector.
-
GDPR compliant
A plain-language privacy policy, deletion on request, and the full list of our subprocessors.
