You have probably wondered how to know which of your contacts are no longer bringing any profit to your business. Well, there is a very easy way to filter them. You only need to create a Segment of inactive users and voila - you will see which of your contacts are harming your sender reputation as they are not opening your emails or marking those as spam. And, approximately 30% of emails go bad in just a year, so maintaining your contact list regularly will help you keep good open and click rates!


Before You Start

Please note, Segments are available on the Standard, Pro and Free Trial plans. Moreover, if you have just created an account with Omnisend, there will be no data about the customers' email activity and the segmentation rule described in the article will not work. 

To create the Segment, please go to Audience > Saved segments  > New Segment.

Once you click on it, you should see the following table (image below).

The best name for the Segment would be "Inactive contacts" but you can choose whichever you like.

The segment rules should be based on Email activity > not opened campaign > any campaign > that was sent > in the last > (we recommend selecting the last year, so 12 months would be the best but you can go for other period of time) > months


This is how the Segment should look:

Once you have all your contacts filtered you can delete or unsubscribe them, which is what we recommend, as they are usually the ones reporting your campaigns as spam just because they forgot they subscribed at one point.

To delete or unsubscribe them you will need to select them all and click delete permanently/ unsubscribe. Make sure you are not only choosing the first 25 contacts.
