Mailbox providers are very selective with what they let in the inbox. To judge whether or not to deliver messages to the inbox, each mailbox provider has created their own sender reputation calculation to evaluate an incoming sender and their mail.
At Return Path, we’ve created our own scoring system—Sender Score—that evaluates similar reputation criteria to give senders a benchmark for how they and their messages are perceived by mailbox providers.
In the 2017 Sender Score Benchmark, we take a look at the impact of reputation and Sender Score on email performance, including:
- The average delivered rate
- The impact of complaints, spam traps, and unknown users
- The average inbox placement rate at Microsoft, AOL, Gmail, and Yahoo
- The average Sender Score and inbox placement rate by industry
- And more!
