Entries
Re:Maily saves a copy of every message that goes through, even when its mail fails, so nothing is lost. Messages sent in test mode, or from a form with Save entries off, aren’t saved.
The list
Contact Form → Entries shows the number of unread entries on the menu. The list has the entry, the sender’s email, the form and the date, with unread entries in bold. Filter it by form, search it, and use Export CSV to download the entries of the form you filtered by.
One entry
Opening an entry marks it read. It shows every value with its mail tag, then the details of the visit: the form, the page it was sent from, the user if they were logged in, the IP address and the browser. A red note says when the mail for that message couldn’t be sent.
Uploaded files are sent with the mail and then deleted; the entry keeps their names.
Keeping and removing entries
In Settings → Entries, Keep entries for deletes entries older than the number of days you set, once a day. Leave it at 0 to keep them until you delete them. Turn on Remove everything when the plugin is deleted to remove forms, entries and settings along with the plugin.
Visitor’s IP address and browser, also in Settings → Entries, sets what entries and webhooks keep of each visit: the shortened IP (its last part dropped, such as 192.168.1.0) and the browser, the full IP and the browser, or neither. Shortened is the default and is usually enough under the GDPR. Spam checks use the full IP either way and don’t keep it.
Entries aren’t included in Tools → Export, so demo content and site exports don’t carry visitors’ messages.
Privacy
WordPress’s Tools → Export Personal Data and Erase Personal Data find a person’s entries by their email address.
