Moosend campaigns go out over its Mailendo sending infrastructure, which your DMARC policy can't vouch for until you add Moosend's SPF include and DKIM selector to your domain.
Moosend runs on Mailendo infrastructure, so its SPF include is spfa.mailendo.com (full record v=spf1 include:spfa.mailendo.com ~all) and its DKIM is a TXT record at the fixed selector ms._domainkey, whose value you copy from the Moosend senders page. Add both, verify in-app, and your campaigns align to your own domain instead of Moosend's. Source: docs.moosend.com · verified 2026-07-15
p=none and a rua address, watch reports for a week, confirm this sender shows 100% pass.No. Adding SPF includes and DKIM records only adds authentication — it never blocks existing mail. The only risky step is tightening your DMARC policy, and that comes later, after reports confirm everything passes.
Send yourself a test email and inspect the headers for spf=pass, dkim=pass and dmarc=pass — or just watch your DMARCKeeper dashboard: the sender's pass rate should hit 100% within a day or two.
Yes. SPF and DKIM authenticate mail; DMARC is what tells receivers to BLOCK mail that fails, and it's the piece Gmail, Yahoo and Outlook now check for explicitly.
