Mail Settings instruct SendGrid to apply specific settings to every email that you send over SendGrid's v3 API or SMTP Relay. These settings include how to embed a custom footer, how to manage blocks, spam, and bounces, and more.
For a full list of Twilio SendGrid's Mail Settings, and what each one does, see our Mail Settings documentation.
You can also manage your Mail Settings in the Twilio SendGrid App
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 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@example.com 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.
Bearer <<YOUR_API_KEY_HERE>>The on-behalf-of header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts. You will use the parent account's API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account's ID (e.g., on-behalf-of: account-id <account-id>). When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g., on-behalf-of: <subuser-username>). See On Behalf Of for more information.
Indicates if your email address whitelist is enabled.
Either a single email address that you want whitelisted or a domain, for which all email addresses belonging to this domain will be whitelisted.
