How an email reputation is formed

Let’s go over how email sender reputation is formed. This is the score that Internet Service Providers (ISPs) assign to businesses and organizations that send out emails. You want to make sure your business has a high score. The higher your email sender reputation score, the more likely your emails will be delivered to recipients.

If your email reputation score drops below a certain level, the emails may begin to go into a recipient’s spam folder. In the most extreme cases, the emails will simply be blocked entirely. You definitely want to avoid that happening if you count on your email list for leads and sales.

There are a number of factors that are involved in ISPs deciding what that score is. These usually include:

  • How many emails you are sending out
  • How many recipients mark your emails as spam
  • How frequently your emails drop into ISP spam traps
  • Whether your business appears on blacklists
  • How many of your emails bounce
  • How many recipients are opening, replying to, forwarding, and deleting your emails
  • How many recipients are unsubscribing to your email list

As you can see, there are several factors at play when it comes to determining what your email reputation will be. Also, every ISP will determine the reputation differently. Some of the factors listed above will carry more weight than others. That means you could have different reputation scores according to different ISPs.

A good way to increase your domain email reputation is to boost the response time on your emails. When ISPs are considering how to score your email reputation, response time becomes the most heavily weighted factor. That means you will want to ensure you are sending out emails during peak times when your recipients are the most likely to check their email. This is usually in the morning of wherever your recipients are located.

An example of a tactic that leads to a lower domain email reputation is sending out too many emails to your recipients, especially if they lack value. That is one of the quickest ways to incentivize people to mark your emails as spam. Once enough recipients do this, you are going to find it incredibly difficult for your emails to avoid going into spam folders or get blocked entirely.

Every ISP and tool out there is basing its score on a different data source. That is why a single score can never provide the full story of what is going on with someone’s email reputation.
