Email Delivery: questions and answers

Answers to the questions people ask: 24 of them, free to read before you buy.

  1. How do I know whether my site has this problem?Go to Email Delivery → Send a test, put in an address you can open, and press the button.
  2. Why does WordPress email go missing in the first place?Without Email Delivery or another SMTP plugin, WordPress hands its email to whatever the web server has arranged, which receiving servers often distrust.
  3. What is a "mail service" and do I have to pay for one?A company whose business is being trusted by the servers that receive email: Gmail, Microsoft 365, SendGrid, Mailgun, Postmark, Brevo and so on.
  4. My username and password are right and it still says they are wrongThey are probably not the ones the service wants.
  5. A customer says they never got their order emailOpen the order in WooCommerce → Orders.
  6. A customer says their email never came, but the log says SentOpen the message from the log by clicking its subject.
  7. Why do my WordPress emails go to spam?Email Delivery's From Domain panel finds the usual cause of WordPress email landing in spam: missing or faulty SPF, DKIM or DMARC records on the domain of your From address.
  8. How do I know my mail password still works?The plugin can check once a day, by signing in to your mail service and straight out again, with nothing sent.
  9. I send through Microsoft 365. Will my email stop?It may, if the site signs in with a password.
  10. The test says "connection timed out"Your web host is most likely blocking outgoing connections on that port; some hosts, DigitalOcean among them, block 25, 465 and 587 altogether.
  11. The test says the sender is not verifiedThe From address is not one your mail service will send as.
  12. Does this store the emails my site sends?No, not the messages themselves — not by default.
  13. Is my mail password safe in the database?Safer than usual, and the honest answer has a limit in it.
  14. Can I set the mail settings in wp-config.php?Yes.
  15. I moved my site and now email has stoppedAfter a move to a new address, Email Delivery holds the site's email until you confirm the move, so that a copy of a site never emails real customers.
  16. Will my staging site email my customers?Not with Email Delivery.
  17. Will this conflict with my other plugins?It should not.
  18. Why does it show a notice in wp-admin as well as emailing me?Because the thing that has broken is the thing an email alert would be sent with.
  19. Can the alert go to Slack or Discord instead of email?Yes, as well as the notice and the email.
  20. The alert says "An email did not reach every address"The mail server took a message for some of its addresses and refused the others, usually an old address in a Cc or a Bcc, or one typed wrong.
  21. Can I use this without a mail service?Yes.
  22. Does opening a message in the log tell the sender I read it?No.
  23. Does it work on multisite?Yes.
  24. What happens if I delete the plugin?Nothing is deleted.
