It is sometimes needed to change your virtual assistant inbox. Due to domain changes or a new name :)
In order to do so for live sequences, you'll be required to create a new virtual assistant and new sequences. If none of the connected sequences are live, feel free to change the address from within the virtual assistant page by clicking again on 'sync'.
Please note, syncing the new email address with the old virtual assistant would create issues for contacts that were already approached by the virtual assistant. Also to consider, contact might reply to the previous inbox, so extra attention is required in the transition.
