Objective
This article shows you how to use the address allow list in Twilio Email settings, so that chosen addresses or domains keep receiving your mail even when bounces or unsubscribes have been logged for them. This is most often used for internal test addresses and critical internal recipients.
Product
Twilio Email
Environment
Twilio Console
User Account Permission/Role(s) Required
You need a role with permission to view and manage email settings. Without it, Settings does not appear under Email in the sidebar.
Procedure
- In the Twilio Console, select Communications in the left sidebar.
- Select Email, then Settings.
- Open the Address Allow List tab.
- Set Enable address allow list to On. The Email Addresses or Domains to allow field appears.
- Enter the addresses or domains you want to allow. Separate them with commas or new lines, and do not put an "at" sign before a domain.
- Select Save Changes. A confirmation message reads "Successfully updated".
- To turn the allow list off, set the section to Off and select Save Changes. The list field is hidden while it is off.
Additional Information
- The field is required while the allow list is on. Saving it empty shows "Email Addresses or Domains to allow is required", and a malformed entry shows "One or more email addresses or domains are invalid".
- This setting ignores all bounces and unsubscribes logged for the entries you add, and future emails are always sent to those recipients as if under normal sending conditions.
- Adding a generic domain such as a large consumer mailbox provider is not recommended: your emails would stop honouring recipient unsubscribes, which may breach anti-spam law and can damage your sending reputation.
