Key findings on email sender reputation<\/h2> <\/div>\r\n \r\n

Mailbox providers are judging you \u2013 sizing you up as a sender and deciding if your emails are inbox worthy or deserve to end up in spam. Your goal is to stay on their good side, which means thinking about your email sender reputation.<\/p>

Sender reputation is often compared to a credit score. Mailbox providers like Gmail and Outlook pay attention to your sending practices and use sophisticated algorithms to assess your reputation. Are you trustworthy? Are your messages anticipated and important? Or would \u201cjunk\u201d be an accurate way to describe what\u2019s being sent?<\/p><\/div> <\/div>\r\n \r\n

What\u2019s your sender reputation score?<\/h2>

Your email sender reputation includes these factors:<\/p>

\u2022 IP and domain reputation<\/p>

\u2022 Email authentication practices<\/p>

\u2022 Sending patterns\/consistency<\/p>

\u2022 Positive and negative subscriber activities<\/p>

\u2022 List quality<\/p>

\u2022 And more…<\/p>

While senders may have knowledge of these things individually, mailbox providers have their own ways of compiling multiple factors into a unique sender reputation score. Unlike a credit score, however, you won\u2019t be able to see your exact number with Gmail, Yahoo, or Outlook.<\/p>

When we asked senders to rate their understanding of sender reputation on a scale of 0 to 10, 25.5% claimed to have a high understanding (8 to 10). More than 42% of senders rated their understanding of sender reputation in the middle (4 to 7) and 32% rated it low (0 to 3)<\/b>.<\/p><\/div>\r\n\r\n <\/div>\r\n <\/div>\r\n\r\n \r\n <\/div>\r\n <\/section>\r\n\r\n

Monitoring your reputation<\/h3>

Since multiple factors contribute to your reputation, and individual providers have their own algorithms for scoring, it\u2019s easy to see why an accurate assessment is tough to come by. High volume senders were the most likely to rate their understanding of sender reputation as strong. That could be because they\u2019ve identified the right tools to help.<\/p>

While Gmail, Outlook, and others may not publish sender reputation scores, there are services that help you keep track of the factors that influence them. That includes Google Postmaster Tools<\/a> for the Gmail ecosystem, Microsoft SNDS<\/a> for Outlook, and the Yahoo Sender Hub<\/a>.<\/p>

However, when we asked senders in our survey if they use these services, adoption was quite low. Nearly 70% of respondents are not using any of the three services from major mailbox providers to monitor sender reputation.<\/b> The most used was Google Postmaster Tools at 28%.<\/p><\/div>\r\n\r\n <\/div>\r\n <\/div>\r\n\r\n \r\n <\/div>\r\n <\/section>\r\n\r\n

Use of these services is much more common among the highest volume senders. More than 63% of those sending over one million emails per month use Postmaster Tools while nearly one-third use Microsoft SNDS. Just over 11% of the largest senders use Yahoo\u2019s service, which is newer in comparison and is adding features for senders.<\/p><\/div> <\/div>\r\n \r\n
