What is Sender reputation
Definition
Sender reputation is the trust score mailbox providers assign to your IP and domain based on volume, consistency, complaints, bounces, trap hits and engagement. It directly determines whether your mail lands in the inbox.
Track it in Google Postmaster Tools and the Mail.ru/Yandex postmasters. Improve it with warm-up, a clean list, authentication (SPF/DKIM/DMARC) and a low complaint rate.
