Gmail forms a large part of a typical B2C email list and can be a challenging mailbox provider (MBP) when it comes to email deliverability. We regularly get asked for the Gmail secret sauce, but it’s not that simple, given they operate a highly sophisticated AI-powered filtering solution. However, there are several practices Gmail likes to see from good senders, and in this blog we’ll take a closer look at them.
Monitor reputation: Good inbox placement starts with understanding how MBPs view senders. Sign up with Postmaster Tools to monitor factors like when Gmail users mark emails as spam, whether messages are authenticating correctly, and the impact on IP/domain reputation and inbox placement.
Implement authentication: Gmail encourages senders to reduce being identified as spam by setting up email authentication. This should be done for each sending domain by publishing an SPF record, and signing with DKIM (using a key of 1024 bits or longer). Senders can then use SPF and DKIM to publish a DMARC record, which helps protect their domain/s against spoofing.
Opt-in, not opt-out: Email programs should use an opt-in permission model, with recipients providing active consent to receive marketing emails. Validate new email addresses either by screening them at point of entry, or using a confirmation process like double opt-in. Ensure addresses generating hard-bounce notifications are promptly suppressed. (We have tools to help you with this!)
Maintain engagement: Gmail places a premium on engaged subscribers, reasoning they have willingly chosen to receive and read their messages, and takes an aggressive approach to recency. Consider using a separate recency threshold for Gmail subscribers, send messages to confirm users want to stay subscribed, and automatically unsubscribe non-responders.
Make it easy to unsubscribe: Always include a prominent unsubscribe link. When subscribers choose to leave, it’s a better option than being marked as spam, or deleted unread – which are negative reputation signals that ding your deliverability. Senders should also include a list unsubscribe record in their email headers, with one-click being the preferred option. Both are in place in this example from New Look.
