List and Segments

Welcome to the community (and Klaviyo)  @JulietteX0 

The more personalisation the better! So, yes, your approach is spot on!

If your master List is double opt-in you may not want confirmation emails sent to those contacts when you import. If so, then create a new single opt-in list ‘Plant Fair’ and import your list into that new list. However, if your Master list is single opt-in, I’d recommend using that list for the import so you maintain a master list for all your contacts.

To identify the plant fair contacts for your campaign, you’ll need to add a custom property. If you may attend events in the future, I would create this custom property as a list data-type. That one custom property will be able to hold multiple values (each event you attend). Let’s call that custom property ‘event_attended’

Steps to import:

• Prepare your .csv. My example below will import email,  event_attended, firstname, lastname. Note that the value in event_attended is enclosed by square brackets and quotations - this lets Klvaiyo know it’s a list
• Select the list for the import (See my comments above) and under ‘Manage list’ top right, choose ‘import contacts’ and then upload your csv
• On the next screen, check the fields you want to import. For 'event_attended' under 'Klaviyo profile property choose 'create a new field'. On the next dialog 'Create a new profile property' select 'List'. Ensure the data type for new 'event_attended' property shows as 'List' when you’re done. Then click the 'Next button.
• On the next screen enable 'Yes, update subscription status for all imported contacts to 'subscribed' i.e as you say they’ve subscribed in person.
• For your follow-up email campaign, create a segment as below. Ensure it uses ‘contains’ and type ‘list’. that’s your sending segment.

I recommend you do all the above on a test list/import so you’re comfortable with the results before tackling the actual list.

Hope that helps but any questions, please let me know
