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, followed by Import Contacts. You will see two options here:
- Upload File
- Upload via 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.
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 keep customers from joining 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 firstname.lastname@example.org 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.
