I created a memebrstack klaviyo integration such that when a new member signs up to our website via memberstack, they are added to klaviyo (along with an External ID, which is the member’s ID on memberstack).
I also want to add an integration such that when a memberstack member updates their email, it also updates their klaviyo email, but I’m not entirely sure how to do it. In zapier I can choose to trigger a zap when a member updates their memberstack profile, but then what I want to do is find that profile in klaviyo (via the External ID) and then update the details. But it seems zapier only allows searching users via email address (which won’t work, since memberstack update trigger already includes the new email, and doesn’t have the old email).
