When an email is rejected by your subscriber's email server- it's called a bounce. It basically an email that never arrives in the recipient's inbox and is sent back.

There are many reasons an email address may bounce, below are some common reasons this could happen.

  • Domain name does not exist
  • Recipient email address does not exist
  • Recipient email server has completely blocked delivery
  • The email cannot be delivered due to an issue with the receiving server.
  • The email has been delivered, but the recipient has an auto-reply enabled on their account. (Soft bounce)
  • The recipient's email server is blocking messages from your email account based on an email history or reputation that indicates you've been sending SPAM.

Requirements

Connection Method: Select the system of connection you want to use
Server: Address of the server you connect to. Example: imap.gmail.com

Delete: If the received message has not been deleted by any plugin, should the system delete the message. If you select "No", the e-mail will stay in the mailbox until you manually delete it. This option should be turned OFFÂ and you should rather use the "forward" or the "save message" capability.
Delete Emails: Upon processing the mailbox, should the system delete the message or email from your external mailbox. If you select "No", the e-mails will stay in the external mailbox until you manually delete it. If you select "Yes" the emails will be automatically removed from your external mailbox. This option should be turn "ON" inorder not to retrieve the same messages everytime and to retrieve the next batch of messages from your external mailbox specially when you have messages more than the preference you specify.

If you are not sure of your server mailbox connection, please verify this with your hosting provider.

Step 4 Verify the connection

  • Once you created your mailbox, try to click Process or Connect to test the connection.
  • If connection is not working, try to create a test Gmail account and test using Gmail credentials if that is working for you.
Important

  • Verify if you have Task running to trigger your mailbox.
