\"Spam <\/a><\/p>\n

It takes just one spam complaint per 1,000 emails to hit Google\u2019s recommended spam complaint rate threshold of 0.1%. Suddenly, that tiny percentage doesn\u2019t seem this tiny.<\/p>\n

So, what makes people reach for \u201cReport spam,\u201d and how do you stop them from getting there? Let\u2019s find out.<\/p>\n

TL;DR<\/h2>\n

Here\u2019s what I\u2019d want you to take away even if you don\u2019t make it to the end of the guide.<\/p>\n

What is a spam complaint rate?<\/h2>\n

A spam complaint rate is the percentage of email messages people mark as spam or junk, that is, complain about them to their inbox providers.<\/p>\n

\"What <\/a><\/p>\n

To calculate it, use this simple formula:<\/p>\n

Spam complaint rate = (spam complaints \u00f7 delivered emails) \u00d7 100<\/strong><\/p>\n

Let\u2019s say you send 10,000 emails and 5 of them get reported as spam. Your spam complaint rate would be 0.05%.<\/p>\n

The calculation itself is simple, but there\u2019s a small nuance to keep in mind. Providers don\u2019t always measure spam complaints the same way. Google Postmaster Tools, for example, calculates its user-reported spam rate based on messages that actually reach the inbox.<\/p>\n

This also means a very low rate isn\u2019t always good news. Google notes that the number can appear unusually low when many of your emails are already being routed to spam instead of the inbox.<\/p>\n
