# Delivering email to Gmail

For new messages to successfully be delivered to Gmail accounts, it is recommended that you review the **SPF/TXT** records on your domain. [Starting November 2022 Google](https://support.google.com/mail/answer/81126#authentication) may randomly performs checks on new sender messages to Gmail accounts. This is to verify that the sender is authenticated with either an **SPF** or **DKIM** record. This is not a requirement for existing senders to personal Gmail account, however new Senders who send emails without an SPF or DKIM method will be rejected or marked as spam.

| This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: [example@gmail.com](mailto:example@gmail.com) host gmail-smtp-in.l.google.com \[74.125.130.27] SMTP error from remote mail server after end of data: 550-5.7.26 This mail is unauthenticated, which poses a security risk to the sender and Gmail users, and has been blocked. The sender must authenticate with at least one of SPF or DKIM. For this message, DKIM checks did not pass and SPF check for the domain did not pass. The sender should visit the Google support page for instructions on setting up authentication. |

If you are getting this bounceback, you will need to add the server/IP address that **did not pass** as part of your **SPF** record. We have an article [here](https://support.webcentral.au/s/article/Creating-TXT-SPF-Zone-records) for adding SPF/TXT records.

Below is an example of what you would need to add in your **SPF/TXT**. Please be advised that this is only a guide and you will need to validate your own **SPF/TXT** record syntax. Ensure that you have made a copy of your **SPF/TXT** records before attempting this change.
