Gmail’s Key Rules: Why SPF and DKIM are now essential for your newsletters

Have you ever wondered why your emails don’t reach the correct recipients or end up in the spam folder? It could be because of Gmail’s recent updates to SPF and DKIM – two small but fundamental rules that can make the difference between succeeding with your newsletters or being invisible in your recipients’ inboxes.

Gmail, one of the world’s most-used email providers, has taken a step towards improving email security for its users. SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are two protocols Gmail has started prioritizing for verifying and authenticating emails. But why is it so important, and what does it mean for you who send newsletters?

SPF and DKIM: A more secure communication landscape

Think of SPF and DKIM as access cards for your emails. SPF is like a list of approved sender servers for your domain, while DKIM adds a digital signature to prove that the message is genuine and not tampered with in transit. When Gmail receives your email, it looks for these “pass cards” to determine if it’s legitimate and safe to deliver to the recipient.

Why it’s essential for your newsletters

For you who send newsletters, this is a game-changer. SPF and DKIM help build trust in your emails with email providers like Gmail. When your newsletters are correctly authenticated, there is an increased chance that they will end up in recipients’ inboxes and not be classified as spam.

How to adapt to the change

Implementing SPF and DKIM for your outgoing emails is relatively easy. It involves configuring DNS records for your domain and adding the necessary authentication keys. By ensuring that your email infrastructure is properly set up with SPF and DKIM, you can ensure that your newsletters reach recipients without problems.


Gmail’s new rules around SPF and DKIM are a reminder that email security and authentication are becoming increasingly important. For those who send newsletters, now is the time to review your email configuration and ensure it complies with these new rules to avoid your messages ending up in the spam folder. SPF and DKIM are the keys to ensuring your newsletters reach the correct recipients and provide maximum impact. So be ready to adapt and ensure a safer and more efficient delivery of your important messages!
