Is MergeMail safe?

Clean risk

MergeMail reads Gmail compose content — body, subject, and all recipients — and sends it to mergemail.co before each email is sent.

When a user composes or previews a Gmail message, the extension collects the full email body, subject line, and all recipient addresses (To, Cc, Bcc) via the Gmail compose API. This data is POSTed to www.mergemail.co/campaigns/prepare through the extension's background script on the presend event. The user's Gmail address is also transmitted as a URL parameter when the extension loads its sidebar iframe.

Where it sends data

Destinations our analysis observed MergeMail contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • www.mergemail.co

    MergeMail sends data to www.mergemail.co. No other extension we have analyzed sends data here.
