What is an SPF record?
An SPF (Sender Policy Framework) record is a DNS TXT record that tells email providers which servers are allowed to send emails from your domain. It helps prevent spoofing and ensures your legitimate emails reach the inbox. **Only one SPF record should exist per domain.**

Common SPF Questions
What is an SPF record?
An SPF record is a TXT record in your DNS that specifies which mail servers are permitted to send email on behalf of your domain.
How do I add an SPF record in DNS?
Login to your domain provider (like GoDaddy or Cloudflare), find DNS settings, add a new TXT record with host '@' and paste the SPF string we generated.
Can I have multiple SPF records?
No. You should only have one SPF record per domain. Multiple SPF records will cause authentication failure.
What happens if SPF is missing?
Without an SPF record, your emails are more likely to be marked as spam or rejected by major providers like Gmail and Outlook.
Does SPF improve deliverability?
Yes. It verifies your identity to the receiving server, which increases trust and helps your emails reach the inbox.
