What is Gmail’s Relevance Filtering (2024–2025 update)?

Still have a question, spotted an error, or have a better explanation or a source we should cite?

You might assume that landing in the Promotions tab means you've made it. Your email is delivered, it's sitting there, job done. But since 2024, Gmail has been doing something more than just sorting your emails into tabs. It's ranking them.

Gmail's Relevance Filtering takes every email inside a tab (Promotions, Updates, Social) and orders them by how relevant Gmail predicts that specific message will be to that specific user. So even if you land in Promotions, you might be third from the top or buried somewhere the reader never scrolls to. (And most people don't scroll far.)

What signals does Gmail use to predict relevance? Mostly your past relationship with that subscriber. Did they open your last few emails? Did they click? Did they ever reply, forward, or save one? Did they recently make a purchase? These engagement signals tell Gmail whether your next email is worth surfacing at the top of the tab or letting it fade into the pile.

This is why sending more emails to unengaged subscribers can actually backfire. If someone hasn't opened in six months and you keep sending, Gmail learns that your emails aren't relevant to them. Their disinterest becomes a signal. It doesn't just affect that one subscriber either. Consistent low engagement across your list quietly pulls down your overall visibility inside Gmail.

The practical shift this creates is a move away from volume toward quality. A list of 5,000 people who genuinely look forward to your emails will outperform a list of 50,000 lukewarm addresses in Gmail's eyes. That's the real takeaway from this update.

Help me improve my Gmail relevance ranking

My promotional emails land in Gmail's Promotions tab but I'm worried they're getting buried by Gmail's Relevance Filtering. Based on what I tell you about my sending habits and list, give me a ranked list of changes I can make to improve my relevance score with Gmail in 2024-2025. Ask me: (1) How often do I send? (2) What is my average open rate and click rate? (3) Do I segment by engagement? (4) How old is my list and when did I last clean it?
