Why am I getting a lot of email delivery failure notifications?

1. Check the email address spelling: First, double-check the spelling of the email address you are sending to. Email delivery failure notices often occur when the email address is typed incorrectly.


2. Verify the contact exists: Email delivery failure notices can also occur if the recipient account or contact does not longer exist, or if the contact is no longer accepting emails.


3. Check the blocked senders list: If the contact exists, then double-check the blocked senders list to ensure the email address is not blocked or blacklisted.


4. Verify SPF and DKIM settings: To ensure emails are being delivered properly, ensure your SPF and DKIM settings are configured correctly.


5. Check email bounces: Email delivery failure notices can also result from email bounces (i.e., if the contact’s mailbox is full). Be sure to check your email bounce logs to identify any issues.
