Email Domain Customization

How to send all Deeper Signals system emails from your own email domain.

Updated over 2 weeks ago

Overview

Email domain customization allows admins to send all account emails from a custom email address, instead of the default Deeper Signals sender address.

This helps organizations maintain brand consistency and improve trust and deliverability. The setup requires adding TXT records to your domain’s DNS to verify ownership.

What this feature does

With email domain customization, you can:

  • Replace the default Deeper Signals sender address ([email protected]) with your own email

  • Add a custom sender name for outgoing emails

  • Ensure emails are sent on behalf of your domain after verification

Important: DNS verification is required before the custom email address can be used.

Adding a custom email address

To add a custom email address:

  1. Navigate to Settings → Integrations → Email domain customization

  2. Select Edit

3. Enter the email address you want to send emails from

4. Add a sender name (optional)

5. Click Confirm

Once confirmed, the platform will generate DNS records needed for verification.

Verifying your email domain

After submitting your custom email address, you will receive two TXT records.

These records must be added to your domain’s DNS settings by a domain administrator.

  1. Copy the provided TXT records

  2. Add them to your DNS server

  3. Return to the platform and select Request verification

Note: DNS changes may take anywhere from a few minutes up to 72 hours to fully propagate.

Once verification is complete, all outgoing account emails will be sent from your specified email address.

How to add a TXT record

The exact steps depend on your domain host, but the general process is outlined below.

  1. Sign in to your domain host account

  2. Locate the DNS management section

    • This may be called DNS Management, Name Server Management, or Advanced Settings

  3. Find the existing TXT records for your domain

  4. Add a new TXT record for the domain (and any required subdomains)

  5. Save your changes

Verifying the TXT record

You can confirm that the TXT record has been added successfully using a command-line tool.

Unix or Linux

dig TXT example.com

Windows

nslookup -type=TXT example.com

The response should appear on its own line and look similar to:

example.com.3600 IN TXT"verification-code=abcdef12-3456-7890"

Tip: If the record does not appear immediately, wait and try again later. DNS propagation can take time.
