SPF Compression and Its Role in Email SPF compression is more than just a technical buzzword; it’s an essential practice that enhances the functionality of your email authentication strategies. The Sender Policy Framework (SPF) specifies which servers are permitted to send emails on behalf of a domain, using a simple text record that contains relevant…
Can You Have Multiple SPF Records? The crux of the matter is that you cannot have multiple SPF records for a single domain.

The SPF protocol works efficiently only when your domain’s SPF record doesn’t have even a minor error. SPF is a highly sensitive email authentication mechanism; even a slight error can cause false positives or completely disrupt the authentication process. One way to evaluate the correctness of your SPF record is by regularly running it through…
There’s a common misconception among domain owners when it comes to email authentication protocols— we have configured SPF, DKIM, and DMARC, so we’re completely safe.

On the other hand, SendGrid claims to send 148+ billion emails every month. And at the same time, there has been a massive 202%…
SPF (Sender Policy Framework), one of the three email authentication protocols, enables recipient email servers to verify whether or not the email received is an authorized one. However, SPF comes with its own set of intricacies, as there is a limit of 10 DNS lookups. Once the SPF record has reached the maximum limit of…
