# Settings - Mail

Mail Settings instruct SendGrid to apply specific settings to every email that you send over [SendGrid's v3 API](/docs/sendgrid/api-reference/mail-send/mail-send) or [SMTP Relay](/docs/sendgrid/for-developers/sending-email/building-an-x-smtpapi-header/). 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](/docs/sendgrid/ui/account-and-settings/mail/).

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