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 Footer mail settings.
The Footer setting will insert a custom footer at the bottom of your text and HTML email message bodies.
You can insert your HTML or plain text directly using this endpoint, or you can create the footer using the Mail Settings menu in the Twilio SendGrid App.
Bearer <<YOUR_API_KEY_HERE>>Optional
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.
