Open Rate Cheat Sheet

What is an Open rate?

“Opened” denotes the number of prospects who have opened the email and “Open Rate” denotes the ratio of “Opened” to the total number of Prospects contacted. The higher the rate the better.


What are the reasons for a low or declining open rate?

If your open rate is below the industry benchmark, there are definitely some inherent issues with the campaign. Possible reasons might be:

  • Non-effective subject line
  • Inadequate testing
  • Non-personalization of emails
  • Frequency of emails to the same prospect
  • Prospect list quality
  • Irrelevant content
  • Mobile Optimization
  • Sending day and time
  • Customers are not interested in the content
  • Use of keywords that trigger the spam filter
  • Inability to keep subscribers engaged
  • Email list containing bounced email ids
  • Double opt-in option not used
  • An issue with the email open tracker
  • Emails landing in social or promotional inbox
  • Emails Landing in spam

Is it possible that my emails are opened but the open tracking is not working?

There is a possibility that your open rates are good but not tracked effectively. So let's understand how it works
Open tracking works by inserting a tiny one-by-one pixel image in the email before it’s sent to the recipient. Email open rate relies on the download of such a graphic image, it isn’t 100% accurate. There can be multiple reasons why the image doesn't download

  • Many ISPs, as well as users, never load the graphics in an email.
  • Many users prefer to receive emails in text format only. In this case, also, the graphics are never loaded, and although opened, will not be marked as opened.
  • Users who use mobile to read their emails, read-only the text version of the email. Hence the graphics are never loaded
  • Non-HTML (text) emails are not tracked at all (as the graphics are not loaded at all in such emails).
  • Some email-reading applications do not allow open emails to be reported.
