Bounce Address Setup 

Bounce emails are emails that failed to deliver. The email delivery failure might be due to permanent reasons (hard bounces) or temporary reasons (soft bounces). Some of the common reasons are:

  • Recipients mailbox is full
  • Recipient has left the organization and his mailbox is deleted
  • Recipient server did not accept emails
  • You may have typed an incorrect email address

Such bounced emails are returned back to a specified address called bounce address. This helps you to understand the delivery issues and sort them out. Bounce address is also called as mail-from address or return-path address. It is mandatory to specify a bounce address before you can send an email. For adding a bounce address you have to add CNAME record to your DNS. Go to Domain Verification page to know how to add CNAME record to your DNS.

Note:

  • Bounce Address can be created only for verified domains (SPF, DKIM, and CNAME).
  • Information about bounced emails can be viewed in the Processed Email tab within your Mail Agent.

Create your Bounce Address

You can go to a specific Mail Agent and add the bounce address under the domains section or directly go to the Domains tab on the left panel and create it under a domain.

Create Bounce Address within a Mail Agent 

  1. From the left panel, click on Mail Agents and select a Mail Agent where you want to create the bounce address.
  2. Navigate to Domains tab. If you have already verified your domain (SPF, DKIM, & CNAME) then proceed to the next step. If your Domain is not verified, go to the Domain Verification section to learn how to complete the domain verification process. 
  3. Click on Bounce Settings for the domain for which you want to add Bounce Address.
  4. Enter the bounce address name and click on Add.

Add multiple Bounce Addresses to your domain

If you want to send different types of transactional emails like welcome emailers and notifications from the same domain but want to receive the bounces for welcome mailers and bounces for notifications in separate mailboxes, then you need to create more than one bounce address for this domain.

Hover over the domain and click on the Bounce settings option to add more bounce addresses using the steps given above.

Add multiple Bounce Addresses

Set a default Bounce Address

If you add multiple bounce addresses to your domain, then you can set one of the bounce addresses as your default bounce address. That means, if you fail to mention the bounce address in your SMTP/ API, the default bounce address will be used as the bounce address. You can set a bounce address as default by click on the Set as default button. The default bounce address is indicated by the green tick mark icon. If there is only one bounce address added for a domain, then it becomes your default bounce address. 

 Set a default Bounce Address

Delete your Bounce Address

  1. Go to the Domains section within your Mail Agent or click on the Domains tab on the left panel.
  2. Identify the domain whose bounce address has to be deleted.
  3. Hover over your domain to view Bounce Settings on the right corner.
  4. Click on Bounce Settings.
  5. The BOUNCE ADDRESS SETUP box will appear. Click on the delete icon for the bounce address you want to delete. Click on OK to confirm the deletion.

If a deleted bounce address is used in your API, you will receive SM_113 error. Refer API error codes here.
