What SPF does

SPF is a simple email-validation system that detects spoofing: it lets you define exactly which IP addresses may send mail for your domain. That list lives in your domain's DNS as a specially formatted TXT record. Because spam and phishing often use forged "from" addresses, publishing an SPF record is a core anti-spam and deliverability technique.

To make sure your messages reach the inbox and not the Spam folder, add Mailpro to your SPF record: put include:spf.mailpro.com inside your existing v=spf1 TXT record. That's it — no new DNS zone, no downtime.

QUESTIONS

Frequently asked questions

What is an SPF record?
An SPF record is a TXT entry in your domain's DNS that lists which servers are allowed to send email for your domain. Receiving servers check it to confirm your messages are genuine. See the SPF definition for more.
How do I add Mailpro to my SPF record?
Add include:spf.mailpro.com inside your existing v=spf1 TXT record, keeping any other includes you already have. Step-by-step instructions are in our FAQ on configuring SPF with Mailpro.
Do I still need DKIM and DMARC?
Yes. SPF, DKIM and DMARC work together: SPF authorizes your senders, DKIM signs each message, and DMARC tells inbox providers what to do if a check fails. Our deliverability guide explains how.
