How does Mailmeteor tracking work?

Every time you send a campaign with the email tracking enabled, we generate random and unique Mailmeteor IDs for each recipients in order to track opened emails and clicks. These IDs are added as notes to each cells in the "Merge status" column.

Emails data is anonymized and minimized. Mailmeteor never stores the email addresses of recipients who opened or clicked emails. Mailmeteor does not store IP address of your recipient neither.

You can turn off email tracking before sending a campaign by opting out the box "Track emails opened and clicked".
