Of course! They’re your email addresses.
There are a couple ways to export email addresses; it just depends on what you’d like:
Export from Mailing List
It’s pretty simple. In the mailing list you wish to export, click on Manage Subscribers and choose Export Subscribers. This will export your email addresses in a CSV file for the list you’re in.
Export All Email Addresses
To export all of the email addresses we have for your account, click on the grid menu icon in the upper right corner. Choose Visitor Search. On the Visitor Search page, there is a drop-down on the left side with an option to Export All Visitors.
