Follow the steps in the video below to connect your GetResponse account to ThriveCart.
By default With GetResponse they setup your campaigns with double opt-in enabled.
This means anyone who tries to join your list, will get an email notification requiring them to confirm before they are actually added to your list.
This can cause a loss in subscribers, and prevent your customers from being added automatically by Thrivecart to your lists when they progress through the cart.
Luckily there's a way around this and requires changing a setting on each list.
Follow the instructions beneath to switch to single opt-in.
