      summary: Update address whitelist mail settings
      tags:
      - Mail Settings
      description: '**This endpoint allows you to update your current email address
        whitelist settings.**


        You can select whether or not this setting should be enabled by assigning
        the `enabled` field a `true` or `false` value.


        Passing only the `enabled` field to this endpoint will not alter your current
        `list` of whitelist entries. However, any modifications to your `list` of
        entries will overwrite the entire list. For this reason, you must included
        all existing entries you wish to retain in your `list` in addition to any
        new entries you intend to add. To remove one or more `list` entries, pass
        a `list` with only the entries you wish to retain.


        You should not add generic domains such as `gmail.com` or `yahoo.com`  in
        your `list` because your emails will not honor recipients'' unsubscribes.
        This may cause a legal violation of [CAN-SPAM](https://sendgrid.com/docs/glossary/can-spam/)
        and could damage your sending reputation.


        The Address Whitelist setting allows you to specify email addresses or domains
        for which mail should never be suppressed.


        For example, if you own the domain `example.com`, and one or more of your
        recipients use `[email protected]` addresses, placing `example.com` in the
        address whitelist setting instructs Twilio SendGrid to ignore all bounces,
        blocks, and unsubscribes logged for that domain. In other words, all bounces,
        blocks, and unsubscribes will still be sent to `example.com` as if they were
        sent under normal sending conditions.'

        The Bounce Purge mail metting allows you to configure the maximum age of contacts
        in your hard and soft bounce suppressions lists. All contacts older than their
        respective configured age are deleted.


        A hard bounce occurs when an email message has been returned to the sender
        because the recipient''s address is invalid. A hard bounce might occur because
        the domain name doesn''t exist or because the recipient is unknown.


        A soft bounce occurs when an email message reaches the recipient''s mail server
        but is bounced back undelivered before it actually reaches the recipient.
        A soft bounce might occur because the recipient''s inbox is full.


        You can also manage this setting in the [Mail Settings section of the Twilio
        SendGrid App](https://app.sendgrid.com/settings/mail_settings). You can manage
