KnowledgeOwl uses a mail delivery provider to send automatic emails like:
- Author welcome and password reset emails
- Reader welcome and password reset emails
- Contact form submissions
Our mail delivery provider keeps track of email bounces and errors.
If a bounce occurs because the intended recipient's email address is returned as invalid, nonexistent, or temporarily misconfigured, our mail provider adds that email address to a suppression list.
Suppression lists are tools mail delivery providers use to help protect your email reputation, by preventing you from sending a bunch of emails that will bounce.
Once an email address has been added to this suppression list, no further emails will be sent to the email address unless you remove the email address from the suppression list.
For the email types listed above, KnowledgeOwl will throw a prominent warning when an email is having issues. When you view the details for that email address, we'll indicate if an address has been added to that automatic suppression list and give you the option to remove it from our suppression list so you can restart sending email to it.
