Before MailerPath can dispatch any email, your sending domain must be verified. Without this step, all send attempts fail with a provider configuration error.

​
Why domain verification is required

Email providers use domain authentication to confirm that mail is genuinely coming from the domain it claims. Without verified DNS records, your emails will be rejected or land in spam. MailerPath uses your verified domain to authenticate every send: transactional, campaign, and workflow.

​
What you need to verify

Verification requires adding DNS records to your domain:
Record typePurpose
SPFAuthorizes MailerPath’s sending servers to send on behalf of your domain.
DKIMAdds a cryptographic signature so receiving servers can verify message integrity.
Your DNS provider is wherever you manage your domain — Cloudflare, Route 53, GoDaddy, Namecheap, or similar.

​
How to add and verify your domain

  1. Go to your MailerPath account settings and locate the Sender domain section.
  2. Enter the domain you want to send from (for example, yourdomain.com).
  3. MailerPath generates the required DNS records (SPF and DKIM values).
  4. Log in to your DNS provider and add those records exactly as shown.
  5. Return to MailerPath and trigger domain verification.
  6. Verification runs a DNS lookup to confirm the records are live.
DNS propagation typically takes a few minutes but can take up to 48 hours depending on your provider’s TTL settings.

​
After verification

Once your domain is verified:
  • MailerPath creates a client-scoped sending credential scoped to your domain.
  • Your from_address and sender settings become active.
  • Campaigns, workflows, and transactional sends can all dispatch.
You can review the current sender configuration under Brand and sender settings.

Common issues

Verification fails immediately
  • Confirm the DNS records were saved correctly (no extra spaces, correct subdomain prefix).
  • Check that your DNS provider has propagated the changes using a tool like dig or an online DNS lookup.
Emails deliver but land in spam
  • Verify both SPF and DKIM records are present and passing.
  • Confirm the from_address matches the verified domain.
  • Avoid sending from a subdomain that is not explicitly included in your SPF record.
Sender domain configuration missing error on send
  • The domain was not added or verification was not completed.
  • Re-run verification from settings.
