How to Quick Add a Subscriber to an Existing List on Klaviyo

We all know that if you have a lot of contacts, the easiest way to add all of them is using the upload file on Klaviyo. If you only have a handful of individuals to your list, you can also use the Quick Add option instead. This is way faster for it directly adds the contact to the list, though it has its limitations.

Please be advised to never add contacts to a subscriber list that have not intentionally opted-in -because this is against Klaviyo’s Terms of Service. Klaviyo 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.

So let’s walk you through where to access the quick add feature.
