Custom sender email addresses can only be configured by a tenant owner.

Self-hosted customers can configure custom sender emails, but need to talk with the team in your organization that manages your SMTP server to assist.

The default sender email address for emails sent with the email action is `mail@tines.io`.

### Configuring a custom sender email address

Visit **Settings **> **Sender emails **or `https://<tenant-domain>/settings/sender_email_addresses` and click the "+ Add Address" button, as shown in the top right of the below screenshot.

![Add a sender email address modal with two fields, the first for an email address and the second for a mail from domain. The bottom of the modal has a button with the text "Save email address"](https://www.datocms-assets.com/55802/1699969987-screenshot-2023-11-14-at-13-52-50.png)

In this form you will need to enter:

1. The email address you wish to use (e.g., [user@example.com](mailto:user@example.com))
2. The MAIL FROM domain (MAIL FROM domain must be the a subdomain of the domain using in the email address, e.g., tinesmail.example.com for example.com)

> **WARNING:** You won't be able to use an no-reply or donotreply email (e.g., no-reply@example.com) as this could cause issues with deliverability due to their email reputation.

The resulting screen will provide two DNS records, a MX record and a TXT record, that will need to be configured in your DNS provider, and you will receive a verification email. Please note that DNS verification may take up to 72 hours to propagate.

If you're adding multiple custom sender emails, you'll have to configure each of their DNS records (MX and TXT) separately. However, if you are adding multiple custom sender emails with the same domain (e.g., acme.com as the domain, and support.acme.com and legal.acme.com as the custom sender emails), you can only add one MX record for that domain, as multiple MX records will not verify successfully. See [AWS docs](https://docs.aws.amazon.com/ses/latest/dg/mail-from.html#mail-from-set) for more information.

> **NOTE:** Tines custom sender email supports SPF but not DKIM at this time.

### Using a custom sender email address

Once verification is complete, select the send email action and add the "Custom sender address" from the "+ Option" menu. You can now enter the email in the "Custom sender address" field.
