Set up a custom domain for the Email Marketing app

Last updated on October 28, 2026

Set up a custom domain for Email Marketing

Using a custom domain allows you to send emails from your own branded domain instead of a shared sending domain. This helps improve inbox placement and customer trust.

Step 1: Open Custom Domain Settings

  1. Go to the Email Marketing app
  2. Click Settings

  3. In the Custom domain section, click Manage custom domain

Step 2: Enter Your Domain

Enter the domain or subdomain you want to use for sending emails. Enter only the domain, such as example.com—not an email address, www.example.com, or a URL.

Once the domain is verified, emails send from info@ followed by the domain you entered. For example, entering example.com sends emails from [email protected]. This sending address cannot be changed.

You can also enable:

  • Warmup – gradually increases sending volume over the first 30 days. During this period, emails above the daily warmup limit are sent from the default Vitals address.
  • Use DMARC – adds an extra layer of email authentication.

Click Authorize to continue. If you authorized the wrong domain, delete the domain and authorize the correct one again.

Step 3: Add DNS Records

After authorization, you will see a list of DNS records.

  2. Log in to your domain provider (e.g., GoDaddy, Namecheap, Cloudflare)
  3. Add each DNS record shown in the app. For the Name field at Shopify and most domain providers, enter only the part before your domain: auth, s1._domainkey, and s2._domainkey. If you enabled DMARC, also add _dmarc. Paste each record value exactly as shown in the app. If you use Cloudflare, set the CNAME records to DNS only (grey cloud), not proxied.

Step 4: Wait for DNS Propagation

DNS changes may take 10 minutes to 24 hours to update.

Step 5: Verify Your Domain

  1. Return to the Custom domain page

  2. Click Verify

Once all records are confirmed, your domain status will change to Verified.

Your custom domain applies only to Email Marketing campaigns and automations. Emails from other Vitals apps, such as Pop-ups discount code emails and Product Reviews emails, keep sending from a Vitals address; you can still set their sender name and reply-to address.
