EmailIdea has always maintained that strong email reputation is crucial, also referred to as your sending reputation. This is determined by how mail providers assess their subscribers’ responses towards emails.

Thus, if there are too many spam complaints generated from your email outreach attempts then it will affect negatively on your sending reputation resulting in future messages having difficulties accessing subscribers inboxes.

To find out more about key tools, statistics and tips that can be used in tracking and gaining better understanding of sender’s reputation for emails read on.

Why is sending reputation important?

You may be used for sending a lot of emails with little thought, but you might wonder, “Why is sending reputation important?”

Simply put, a sender’s email reputation determines whether or not their email will get sent to spam or whether it will reach the user’s inbox. On the other hand, when recipients interact with your emails, you build a good sending reputation; therefore, your future messages are likely to be delivered into their inboxes.

According to the Data & Marketing Association’s 2020 Consumer Email Tracker Report, only 58% of individuals check their personal spam folder at least once per day compared to 95% who check general mailboxes on daily basis. This means that for organizations whose aim is maximizing email outreach efforts, sending reputation is key.

What do you mean by check, email reputation?
An email reputation checks involves assessing and keeping an eye on the reputation of your email domain and IP addresses from which you send emails. This email reputation is a significant factor that Internet Service Providers (ISP) and email services use to determine whether your emails should:
- Be delivered to the recipient’s inbox
- Land in the spam folder
- Be blocked entirely


This is very similar to a credit score for your email sending practices – this is what we call an email reputation (often referred to as sender reputation). Factors that contribute to it include:

-Since large amounts of e-mail messages are sent quickly, this can harm a person’s reputation if it is not comparable to their regular way of sending messages.
-Bounce rates: High proportions of messages failing to reach their final destination (bounced mails) may ruin your standing.
-Complaint rates: The ratio at which people opt for junk during e-mailing process
-Engagement: The usage patterns in reading or responding to emails such as opening rate, determining contact opportunities post-click-through or even deleting them without opening.
-Blocklists: One or more mailing lists would indicate that you have most likely damaged yourself badly by losing all credibility as a sender. They are repositories held by different groups containing recognizable sites and IPs responsible for sending unsolicited messages.
