FAQ
- Why do I need to set up a DMARC record?
- It blocks spammers from spoofing your domain and improves how reliably your emails land in recipients' inboxes.
- Can I list multiple sending servers in one SPF record?
- Yes — chain multiple IPs or include statements together, space-separated, in a single TXT record. Just keep in mind SPF has a 10 DNS-lookup limit, so don't stack too many include statements.
- Does the record take effect immediately after I add it?
- DNS propagation usually takes a few minutes but can run up to 48 hours, so check with a tool like nslookup or dig shortly after publishing to confirm it went live.
