What is SPF?
The Sender Policy Framework (SPF) is a security protocol designed to prevent email spoofing. It is essentially a list of IP addresses authorized to send emails on behalf of your domain. Receiving mail servers check each email against this list to ensure it comes from an approved server. If not, the message is rejected or flagged as suspicious.

SPF acts like an entry ticket
Have you attended a concert lately? Security is tight. You can’t get in without a ticket. Often, it’s a digital ticket on your phone with a QR code. The frontline staff at the venue scan that code to verify you are a genuine attendee. Similarly, SPF functions like a meticulous ticket checker for your email system. It verifies whether an incoming email originates from a server that has a valid "ticket" — authorization from your domain to send emails. If the email’s "ticket" doesn’t match the list (your domain’s SPF record), then the email is turned away, not allowed to enter your inbox.

Why do we need SPF?

• Prevents email spoofing: Just like a gatekeeper prevents intruders from entering an event, SPF blocks unauthorized sources trying to send emails pretending to be from your domain.
• Improves email deliverability: Emails sent from SPF-verified servers are more likely to reach the inbox rather than being marked as spam.
• Strengthens your domain’s reputation: A valid SPF record boosts your credibility with mail servers, enhancing the reliability of your communications.

What is email spoofing?
Spoofing is a type of fraud where the sender falsifies the email header to mimic a trusted source. Often used in phishing, it aims to steal sensitive data or spread malware. This technique exploits the trust of victims and can harm an organization. This is why protections like SPF are crucial.

Why does your organization need SPF?
Regardless of your industry or business size, SPF is essential to protect your communications. Here’s why:

• Protect your brand integrity: SPF prevents fraudsters from sending malicious emails pretending to be your company.
• Avoid being blacklisted: Domains linked to fraudulent activities can be blacklisted by email providers, compromising the deliverability of your legitimate emails.
• Build customer trust: When your customers know your emails are secure, their trust in your brand grows.
