The part most people want to know first

mailmymail copies your Gmail messages — including their full contents — to our storage, so campaigns can detect replies and bounces and keep a record of what was sent. If you are not comfortable with that, do not install it.

What we store

  • Your mail. Message metadata (sender, recipients, subject, date, labels, thread and message identifiers) and the full original message, including body text and attachments, for messages in your mailbox.
  • Mail you send through us. The rendered subject and body of every campaign message, and whether it was delivered, opened, replied to or bounced.
  • Contacts you upload: addresses and any columns you use as merge fields.
  • Campaigns you write — subjects and message bodies.
  • Unsubscribes and bounced addresses, so we never mail them again.

Metadata is held in a Postgres database; message bodies are held as files in Cloudflare R2 object storage. Both are private and neither is shared with anyone.

How it gets there

mailmymail requests no Gmail API permissions at all. It reads your mail from inside the Gmail tab you are already signed in to, using your existing session, and uploads it from your browser. We never hold your Google password and cannot access your account when your browser is closed.

What we never store

  • Your Google password. We never see it.
  • Your browsing activity outside Gmail.
  • Anything from other Google services — Drive, Calendar, Photos.

Who can see it

Only you. There is no account system — your data is tied to an anonymous identifier your browser holds — and we do not sell, share or license it to anyone. We do not use it to train anything.

How long we keep it

  • Archived mail and bodies: kept until you delete them or delete your account.
  • Uploaded CSV files: deleted after 7 days. The contacts stay until you delete the list.
  • Lists and contacts: deleted 90 days after you last use them.
  • Send and reply history: 180 days.
  • Unsubscribes and bounces: kept indefinitely, on purpose. Deleting them would let someone who asked not to be contacted be contacted again.

Deleting everything

Deleting your account removes the archived mail and its bodies from object storage, along with your lists, contacts, campaigns and history. Because there are no accounts to sign back into, this cannot be undone.

A note about other people

Archiving your mailbox means storing messages written by people who never agreed to anything with us. We treat that seriously: their data is used only to make your campaigns work, is never sold or shared, and is deleted with your account.

Limited Use

The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
