To add a contact, go to your BranchUp Account click on ‘eMarketing App’ then ‘Contact List’ and click on the icon with the arrow. Make sure you select ‘Add new contact’ when you upload your new list.
You won’t be able to delete a single contact, they will either opt-out from your list or you can ‘replace’ your list with an updated version without the contacts you want to delete. Make sure you select the correct upload option for your list: 1. Add new contacts, or 2. Replace all contacts
