Requirements for all senders

sourced from google page above

Starting February 1, 2024, all senders who send email to Gmail accounts must meet the requirements in this section.

Important: If you send more than 5,000 messages per day to Gmail accounts, follow the Requirements for sending 5,000 or more messages per day.

Set up SPF or DKIM email authentication for your domain.
Ensure that sending domains or IPs have valid forward and reverse DNS records, also referred to as PTR records. Learn more
Keep spam rates reported in Postmaster Tools below 0.3%. Learn more
Format messages according to the Internet Message Format standard (RFC 5322).
Don’t impersonate Gmail From: headers. Gmail will begin using a DMARC quarantine enforcement policy, and impersonating Gmail From: headers might impact your email delivery.
If you regularly forward email, including using mailing lists or inbound gateways, add ARC headers to outgoing email. ARC headers indicate the message was forwarded and identify you as the forwarder. Mailing list senders should also add a List-id: header, which specifies the mailing list, to outgoing messages.

Set up DMARC email authentication for your sending domain. Your DMARC enforcement policy can be set to none. Learn more
For direct mail, the domain in the sender's From: header must be aligned with either the SPF domain or the DKIM domain. This is required to pass DMARC alignment.
For subscribed messages, enable one-click unsubscribe and include a clearly visible unsubscribe link in the message body. Learn more

If you send more than 5,000 emails per day before February 1, 2024, follow the guidelines in this article as soon as possible. Meeting the sender requirements before the deadline may improve your email delivery. If you don’t meet the requirements described in this article, your email might not be delivered as expected, or might be marked as spam. To get help with email delivery issues, go to Troubleshooting.

How JEMHC helps with unsubscribe

We already have an unsubscribe button on outbound notifications that allow users to ‘opt out’ of specific per-issue notifications (as notifications are not a ‘list’), we’ll be looking to extend our approach to support the google requirements for unsub to make use of List-Unsubscribe headers.
