If you really just want to tag a specific list of 2000 emails, and you have the emails in a spreadsheet or CSV file, the easiest way is to upload them into an existing (or new List) and create a new column with a property name and a value for everyone in that list. You can use a Spreadsheet or Excel and quickly drag that value down the list to populate that value to your list of 2000 email addresses.
For example, if you wanted to create a new property name called “Group” and the value is “1” you would have a CSV with a minimum two columns like this:
When you upload this list into Klaviyo, you’ll see that all the profiles will have a Custom Property called “Group” with a value of “1” like this:
Now, you can create a Segment of those folks where the custom property “Group” has a value of “1”.

Shopify Tags get synced to Klaviyo under the Custom Property called “Shopify Tags.” Once the tags are in Shopify you can create a Segment like this:
