Gmail and Yahoo! have unveiled significant updates to their email authentication protocols and spam prevention measures, slated to take effect in February 2024.
These changes could greatly influence the success of your future email marketing campaigns, so it’s essential to stay informed and understand the necessary steps to excel in email marketing in 2024.
The good news is, there’s no need to wait until February to get your email strategy aligned. We’re here to support you throughout this transition!
Let’s start by summarizing the changes introduced by Gmail and Yahoo (sometimes collectively referred to as “Yahoogle”) and identifying who will be affected.
Key Changes in Gmail and Yahoo’s 2024 Authentication Policies
- Using Custom Domains: Send emails from your own custom domain rather than free domains like @gmail.com.
- Email Authentication: Implement DKIM and DMARC protocols to authenticate your emails.
- Spam Complaint Threshold: Maintain spam complaints at a rate below 0.3%.
- Unsubscribe Process: Provide an easy one-click unsubscribe option and ensure unsubscribing requests are honored within two days.
Who Will Be Affected?
Google identifies bulk senders as those dispatching over 5,000 emails to Gmail addresses in a single day, while Yahoo! hasn’t clearly defined their criteria.
If you send fewer than 5,000 emails daily to Gmail addresses, you can bypass the one-click unsubscribe requirement and DMARC, and instead use just SPF or DKIM.
However, once Google classifies you as a bulk sender, this label is permanent.
To err on the side of caution, we advise all email marketers, regardless of their list size or mailing frequency, to adhere to these new guidelines.
