Gmail and Yahoo announcements

December 12, 2023

ANNOUNCEMENT

Gmail and Yahoo recently announced that they're moving towards the "No Auth, No Entry" principle, which means that if the domain names used in the emails you send are not properly authenticated, they will start rejecting the emails as soon as early 2024.

We encourage you to read the announcements from Gmail and Yahoo, but feel free to check this summary from M3aawg.

Splio supports you through this update.

The setup of email authentication is one of the first steps you took when you started using Splio.

However, you may have started using a new sending domain after your onboarding, and potentially, these domains have not been declared, didn't go through a proper DNS setup, and therefore are not authenticated.

Or maybe a user made a mistake and started sending from address@yourdomain.com instead of address@news.yourdomain.com as initially planned.

Either way, we're asking you to review the sending domains you are using to avoid seeing your emails getting rejected by Gmail and Yahoo in the coming months.

As usual, feel free to check our documentation and contact us if necessary!

What is the authentication for?

Mailbox providers' biggest challenge is to accept legit emails while rejecting spams. In order to do this, the first step is to make sure the sender of the email is who he pretends to be, and for two main reasons:

  • If the sender is spoofed, impersonating someone else, chances are that the message is a spam, a phishing, a scam ...

  • If the sender is confirmed to be who he's pretending to be, a reputation can be attached to it.

The authentication process is about telling the mailbox providers that you are allowing Splio to send your emails

How to enable authentication for my emails?

In order for Splio to authenticate the emails you are sending, we ask you to setup a few DNS records on your sending domains, among all:

  • SPF, to tell mailbox providers that you are allowing Splio's IP addresses to be used to send emails using your sending domain

  • DKIM, to show mailbox providers that you are allowing Splio to apply a digital signature to emails sent using your sending domain

  • DMARC, to reinforce the fact that you are allowing Splio to send emails using your sending domain for the visible sender's address, but also to tell that other emails using the same sending domain but which are not properly authenticated, are not legit and should be rejected.

If you have any questions, please contact our customer care or your CSM.
