You can upload an entire huge list of subscribers! (Reminder: Once a subscriber or subscriber list is uploaded, those subscribers will receive your onboarding / "welcome" email if you have this feature on.)

To navigate to this page, go to Audience > Import List (on the left-hand side of the page).

Then, click the "Select File" button to upload your file. 

Here are a few guidelines when uploading your subscriber list:

  • We require a .csv or .txt file that is a maximum size of 2MB. 
  • Subscriber emails are required, and they should always be in column 1 of the spreadsheet
  • Name is not a required field
  • If you include names, place them in column 2 of the spreadsheet
  • If a name is not provided, Cerkl will use everything before the @ of the email for that subscriber's name
  • Select a segment to add the subscribers to if you would like
  • Have open only one tab in Cerkl
  • Scrub list (if necessary)

We provide some images of what your spreadsheet should look like for your upload at the bottom of the Import Subscribers page.

Cool Feature Alert: You don't need to worry about duplicates because Cerkl deletes one of them automatically! Also, Cerkl reads the email as the "key" - so any name updates can be uploaded with the original email and those changes will take effect for that subscriber.

If you have any questions at all, don't hesitate to reach out to us at! Or use the help bot in the bottom right hand corner of any page for a quick answer.
