Setup DKIM: how to add DNS records to your domain

DKIM helps email providers trust your messages. You’ll add a few CNAME records to your domain’s DNS.

Steps

  1. Open your domain’s DNS settings

    Log in to your domain host (e.g., Cloudflare, GoDaddy, Namecheap) and find DNS or DNS records.

    Add a new record

    Click Add record and choose CNAME as the type.

    Fill in “Name / Host / Label”

    • Copy the Name from our file and paste it here.
    • It’ll look like: selector123._domainkey  (yours will differ).
    • Tip: some hosts auto-append your domain. If you see your domain already shown, don’t type it again.

      Fill in “Target / Value / Destination”

    • Copy the matching Value from our file and paste it here.
    • It’ll look like: selector123.dkim.emailservice.com  (yours will differ).
  2. Save the record

    Add all CNAME types to domain

  3. Wait for DNS to update

    Changes usually show up within an hour, but can take up to 72 hours.

  4. Verify in the app

    After adding all records, return to the app and click Send test email and see if the sender email was updated.
