Provider-specific notes for Shopify

  • Shopify Email requires SPF and DKIM for custom sender domains. Follow the verification steps in Shopify Admin → Settings → Domains.
  • If you send transactional email through a third-party ESP alongside Shopify Email, add both providers' SPF includes into one record at your DNS provider.
  • Shopify Admin → Settings → Domains → DNS settings.

What you’ll need

  • Access to Shopify to generate a DKIM key and selector.
  • DNS provider access to publish a TXT record at selector._domainkey.

Generate your DKIM key

In Shopify, generate a DKIM key and note the selector. Providers often suggest something like shopify (auto-configured for Shopify Email).

Shopify Admin → Settings → Domains → DNS settings.

Publish the record

  1. Create a TXT record at host selector._domainkey (replace selector with your actual selector name).
  2. Paste the full value starting with v=DKIM1; k=rsa; p= and save.
  3. Wait for DNS propagation.

Verify DKIM

  • Send a test email to a Gmail address and use “Show original” to confirm “DKIM: PASS”.
  • Or run: 
    dig TXT selector._domainkey.yourdomain.com +short

Common mistakes

  • Using the wrong host so the record becomes selector._domainkey.yourdomain.com.yourdomain.com.
  • Breaking the value by wrapping or truncating the TXT string.
  • Publishing a record for the wrong selector and then validating on another.
