Add Subscribers to an Existing List

Upload New Contacts

If you are interested in adding subscribers to an existing list, first navigate to the list.

Next, click Manage List in the upper right-hand corner. You will see two main options here:

  1. Import from File
  2. Import by Copy/Paste

Both of these options will allow you to add contacts just as you would if you were creating a new list. For instructions on how to do this, click here.

Quick Add

If you would like to quickly add a handful of individuals to your list, you can also use the Quick Add option instead.

A few things to keep in mind:

  • Never add contacts to a subscriber list that have not intentionally opted in -- this is against Klaviyo’s Terms of Service.
  • We will automatically de-dupe all lists -- it's not possible for someone to join the same list more than once. This means if you are trying to import a file containing subscribers that are already on your list, you will notice that these duplicative records will not get added. For example, if you'd like to add a custom property to everyone a list, you can safely re-upload the list with the custom property attached without creating duplicate profiles.
  • We will automatically skip email address entries that do not have a valid format. A valid email address such as jane@example.com is made up of a local part, an @ symbol, then a case-insensitive domain part. If any of the required parts of a valid email address are missing, we will consider the email invalid. If there are erroneous spaces in the email address, we will also consider the email invalid.
