Not relying on email alone.
WHY IT MATTERS
Email fails. Spam filters catch things. Mailboxes fill.
An enquiry that only existed as an email is lost.
WHAT TO DO
Use a form plugin that stores submissions in the site.
Then email is a notification, not the record.
WHAT THIS PROTECTS AGAINST
Delivery failure Accidental deletion A full mailbox rejecting mail
THE FULL MAILBOX CASE
Common and silent. Mail is rejected and you never see the enquiry.
WHERE SUBMISSIONS ARE STORED
In your site's database, visible in the admin.
WHAT TO DO WITH THEM
Check periodically, even if emails arrive.
Comparing stored submissions against emails received tells you whether delivery is working.
DATA CONSIDERATIONS
Stored submissions are personal data.
Delete old ones you no longer need, and say in your privacy notice how long you keep them.
WHAT TO EXPORT
Periodically, if the data matters.
