Hi,
I am looking for a confirmation regarding the potential need of requiring a new consent when moving contacts from one ESP to another. What is the process exactly? Once I upload an audience into a new ESP, should I or should not sent these contacts a new sign-up form, since they will now start receiving communication from another platform?
Thank you for clarifying this point to me 
Chiara
Hi
Welcome to the Community! This is a great question about migrating subscribers from another platform into Klaviyo.
You are not required to get your email subscribers consent again when you are moving platforms, but you definitely want to make sure that those who were previously unsubscribed remain that way in your new Klaviyo account.
There is an awesome Help Center article about this here: How to migrate existing email subscribers (and unsubscribes) into Klaviyo.
Depending on whether you will be migrating to Klaviyo via a direct integration, or you will be manually uploading contacts from a CSV, the article above is a great guide for how you can carry over your existing email subscribers (and unsubscribes) into Klaviyo successfully in each case.
