Spam complaint rate

How it affects cold email

Google asks all senders to keep the spam rate reported in Postmaster Tools below 0.3%, recommends staying below 0.1%, and says to avoid ever reaching 0.3% (Google). Yahoo also uses 0.3%, and calculates its rate only from mail delivered to the inbox (Yahoo).

With thresholds that low, a few complaints on a small campaign matter. The fixes are a relevant list, an honest subject and sender, and an unsubscribe that is easier than the spam button.

How Inboxed handles it

• Every campaign email includes a visible unsubscribe line and one-click unsubscribe headers. People who report spam through Inboxed’s report abuse page go on the suppression list, and those entries can’t be removed.
• Connect Google Postmaster Tools with your own Google account and Inboxed reads your Gmail spam rate daily.
