What is Email Sender Reputation?

An email sender reputation is a score that an Internet Service Provider (ISP) assigns to entity that sends email. It’s a crucial component of your email deliverability.

First thing First. You first need to make sure that your emails actually make it into your customers’ inboxes by ensuring you have a positive email sender reputation.

The higher reputation leads to possibility to deliver emails to the inboxes of recipients and if the score falls below a certain threshold, the ISP may send messages to recipients’ spam folders or even reject them.

Research shows the average US worker receives 121 emails a day. Even if it just takes 30 seconds to read an email, that’s still about an hour of your day. Internet service providers (ISP) want to reduce that and only show their users emails that are wanted.

They’ll use an email sender reputation to determine which email should be placed in inbox and, which emails go into the junk folder, and which needs to be blocked.

Nearly ~ 45% of all emails sent are considered spam

There are several factors which can go in determining the score. below is the list:

  • The amount of email sent by any organization
  • The number of compliants ISP received from recipients for organization’s emails
  • The number of times an organization’s emails marked as spam
  • The rate of hitting the ISP’s spam trap by any organization’s emails
  • The organization’s inclusion on different blacklists
  • Email bounce rate because organization sent emails to unknown users or for other reasons
  • The number of times recipients open, reply to, forward, and delete the organization’s messages, as well as click the links found in them
  • The number of times recipients unsubscribe from the organization’s email list
  • The content of your email.
  • Sender’s IP reputation

Every ISP decides which factors to include and which not in its sender reputation andwhat weights those factors when calculating the reputation for each sender that sends email to its users.

That’s why a sender could have varying reputation scores for different ISPs. And most important, If a sender has multiple domain names and sends email from different IP addresses then each one will going to have its own sender reputation.
