Frequently Asked Questions

SPF (Sender Policy Framework) is a DNS TXT record that specifies which mail servers are authorized to send email on behalf of your domain. When an email is received, the recipient's mail server checks the SPF record to verify the sender is legitimate. This helps prevent email spoofing and improves deliverability.

Complete Your Email Authentication

SPF is just one part of email authentication. Set up DKIM and DMARC for complete protection.

Why You Need an SPF Record

Without an SPF record, anyone can send emails that appear to come from your domain. This makes your domain vulnerable to spoofing attacks and can damage your sender reputation. Email providers like Gmail, Outlook, and Yahoo check SPF records to verify sender authenticity.

Setting up SPF is the first step in email authentication. Combined with DKIM (email signing) and DMARC (policy enforcement), SPF helps ensure your emails reach the inbox and protects your brand from phishing attacks.

The playbook

Three rules. Memorize them.

01

SPF, then DKIM, then DMARC.

In that order. Each builds on the last. Skip DKIM and Outlook quietly junks half your mail.

02

Use DMARC quarantine, not none.

DMARC=none does nothing. Set p=quarantine + rua report email. Catch spoofing in 24h.

p=qpolicy
03

Re-check after every DNS change.

DNS propagates inconsistently. Verify all records hit before you trust the new config.
