Custom Sender Domain allows you to send all emails from TrustSpot using your own From Email, as opposed to using Trustspots default email; 

You have the ability to edit:

With this feature you have the ability to set a From Email connected directly to your domain using DNS settings (ex:

NOTE:   This feature requires technical knowledge of your Domain's DNS. If you're not comfortable setting this up please ask your site administrator. TrustSpot uses Postmark to create custom sender signatures (& domains), so you can use this resource from Postmark to set up DKIM and Return-Path where your domain is hosted.

If you're hosting your domain on your eCommerce platform you can find relevant support articles below with steps to updating the DNS settings:

Set up your Custom Sender Domain in TrustSpot

  • Go to Account Settings > General in the top right corner

  • Email Settings

  • In the "Custom Domain" field Enter the email address you want to send review requests from.

    • NOTE: You must use a domain you own and cannot gmail, yahoo, etc.

  • Click "Setup Email"

  • A window pop-up will show records you must add into your DNS settings to authenticate the domain:

    • DKIM

      • Hostname: ********************

      • Type: TXT

      • Value: ********************

    • Return-Path

      • Hostname: ********************

      • Type: CNAME

      • Value: ********************

  • Go to your domain server DNS settings and input the DKIM & Return-Path settings provided.

  • Once these records are added on your server, go back to TrustSpot and click Finish

  • The verification process can take up to 4 hours. Contact support in case of any questions.

Note: You MUST complete the Setup process before you can start sending from your own domain name. 

Custom Domain verification

Once you click the "Finish" button, you will be shown verification status:

  • DKIM Verified

  • Return-Path Verified

Once DNS propagation is finished, you will see the DKIM and Return-Path verification statuses and you will start sending with the new From Email! If you verification is not updating please contact us at support.

Setting up DMARC

To protect your domain from ending up in spam, you must establish a DMARC record in your DNS settings. Google and Yahoo specifically are cracking down in early 2024 to require each email to have three forms of verification:

  1. DKIM

  2. SPF

  3. DMARC

The first are taken care of with the above implementation, but DMARC must be added to ensure deliverability. In short, DMARC helps to ensure that emails sent from your domain are legitimate and haven't been altered, and it instructs other email servers on what to do if they receive a suspicious email pretending to be from your domain. It's a key tool in preventing email fraud and protecting your domain's reputation. To learn more click here.

To create a DMARC record:

  • Go to your domain DNS settings

  • Create a new TXT record

    • Name: dmarc.{}

    • Record: TXT

    • Value: v=DMARC1\; p=reject\; pct=100\; rua=mailto:dmarc-{insert_owned_email_address_here}\;

  • Save record

For more information regarding this particular set up please consult with your domain admin and consult this helpful support article.
