# What spam rate does Gmail allow?

Spam rate is the share of your delivered mail that recipients mark as spam, and Google asks senders to stay below 0.10% and never reach 0.30%.

By Invenitor team. Updated 2026-11-01.

## Where do those numbers come from?

Google's sender guidelines say: "Keep spam rates reported in Postmaster Tools below 0.10% and avoid ever reaching a spam rate of 0.30% or higher" ([Google](https://support.google.com/a/answer/81126)).

## What does that mean in practice?

At 0.30%, three reports per 1,000 messages is the limit. A few people marking a small batch as spam can do real harm, so write to fewer people and make each message clearly meant for them.
