I’ve set up Klaviyo/Squarespace integration and I can see that the data is being sent by Zapier. Here is the Data Out response to a recent sign up:
A confirmation email was sent to Hello@barnfieldcustoms.com since a double opt-in list was selected for this Zap step. Learn more at https://help.klaviyo.com/hc/en-us/articles/115005251108-Overview-of-the-Double-Opt-In-Process
However, out of the 6 email signups that I’ve had, only 1 has received the opt-in email.
Any ideas what’s going wrong?
