Hi! My business uses Boulevard for client appointment bookings and we just started using Klayvio for email and SMS marketing. We do not have the Boulevard API plan which transfers over all information automatically between the two platforms. I do everything manually 1-2x per week (transferring over client names, emails, phone numbers, and email/sms consent status - they consent to receive messaging from us via Boulevard when booking). 

I am going to frame my question as a hypothetical situation to best describe the scenario:

Someone booked an appointment week of January 1st, so in my transfer batch that week, I get their info over to Klayvio. When they initially booked, they did not consent to receive SMS marketing (which reflects in the info I transferred). They then rebook in July, but this time they consented to SMS marketing. Their name, email, phone  number, etc is all the same, only thing that changes was this one piece of info. 

Will Klayvio recognize this profile and automatically update their old contact/profile info with the new data transfer? Or will it see that it is essentially a duplicate email and ignore the whole thing? I need to make sure contact info is able to be updated in my data transfers between the platforms. 

Thanks!
