LEARN MORE: Define Your Own List Segments


When you take the time to segment your contact lists and send the right message to the right people, you get better open rates and overall engagement with your emails. Segments allow you to create customized groups of contacts by looking at your contacts as a whole, despite how many lists you have, and filtering them into a group by list membership, contact information, and email engagement. Once you've created your segments, they're ready for you when you're ready to schedule an email.

Hi @CharityS2,


That's a great question and thanks for asking! You can create a Segment based on a specific email domain by using the Advanced contacts search function and saving those contacts as a new email list. This resource provides the step-by-step instructions for you: Segment Your Lists Using Contact Details. Please let us know if you need any further assistance with this!

I created a segment listing of individuals who haven't opened our emails.  There are several thousand names, and we want to purge that group.  How do I delete those contacts en-masse?

@DaveM4302 Hi! Creating segments are a great way to help manage your contacts. To purge a segmented group of contacts, you will need to create a list of those contacts and then delete that list. Let me know if I can assist you with anything else!

Hi, I have 2 segment questions:


1.  In addition to the activity parameter of sending to those who were not sent the last 5 emails and those who weren't sent a specific email, do you foresee in the future adding the ability to select those who weren't sent MULTIPLE specific emails of your choosing?  For example, maybe there was an email sent earlier than your last 5 for which you want to be sure your new segment was not sent, in addition to a few other emails that were more recently sent.


2.  Do the segments build on one another? 
i.e. If segment A's parameters are that the contacts did not receive email A, then I send that email B, when I go to email the segment C and say to send to those who didn't receive email B, does that automatically mean it's filtering for those who didn't receive email A OR email B, or just email B?
