Once you've connected your BetterHQ account to your MailChimp account, BetterHQ will automatically send across newly added clients to MailChimp every 30 minutes. There's nothing else required from you. Just log in to your MailChimp account and you'll see you clients' first name, last name and email added to your nominated subscriber audience (or list).
Newly added clients in BetterHQ will be sent across to MailChimp every time. No double entry of data required.
