What is SPF in simple words?

Sender Policy Framework (SPF) is an SPF TXT record that identifies authorized email senders for a domain, helping to prevent email spoofing and increase email security.

SPF records provide a way to specify which IP addresses are authorized to send emails from the associated domain. In other words, they act as a list of accepted sources of emails. So, how does this work?

When an email is sent, the receiving mail server performs an SPF lookup by checking the domain’s SPF record in its DNS settings. If the sender’s IP address is found within the domain’s list of authorized IP addresses, the email passes the SPF authentication and is deemed legitimate.

This process helps ensure that only authorized senders can send emails on behalf of a domain, reducing the risk of email-based attacks and enhancing email security.

An SPF record, which follows the spf specification, starts with “v=spf1” and is followed by one or more mechanisms that define the IP addresses authorized to send email on behalf of the domain. These mechanisms can also include additional domains and IP addresses using the “include” and “redirect” mechanisms

If an email fails the SPF check, it will be rejected, as the receiving mail server has determined that the email does not align with the domain’s SPF record. It is important to note that attempting to publish multiple SPF records can cause issues with email authentication.

An SPF record checker serves as a tool to check SPF record, confirming the existence, format, and functionality of your domain’s SPF record during email dispatch.

Authenticating your emails will be mandatory to deliver your emails to Gmail and Yahoo in 2024

From February 2024, bulk email senders will be required by Gmail and Yahoo Mail to validate their emails using recognized best practices, such as DMARC, SPF, and DKIM on mail servers.

If you send more than 5,000 daily emails to Google and Yahoo addresses, you will have to:

• Authenticate your emails using security protocols like DKIM, SPF, and DMARC.
• Allow people to easily unsubscribe by clicking just one link, and honor unsubscribes within two days.
• Maintain a spam complaint rate under 0.3% (three spam complaints max for every 1000 messages).

All these standards aim to create a safer, more enjoyable experience for the average Gmail or Yahoo email user.

Email authentication makes an organization less vulnerable to spoofing and spam attacks. One-click unsubscribes allow users to opt out of an email list easily. Keeping a minimal spam complaint rate ensures the content people receive in their inboxes is relevant to them.

By adhering to these requirements, bulk senders can ensure their emails are delivered and maintain a strong email reputation.
