We have been using this for our clients.
Pro: Easy to use, and price is low. Not much complex.
Cons: This is still buggy. It takes 5-6 hours, just for updating template. I will give up is this is so. My team is frustrated seeing not getting saved in templates. This is not one time issue, we get every week almost everyday. Branding is not helpful. Customer, see all email from BreezeDoc, Logos, Not recommended if looking as white label to customer.

I am happy to get changed in this review if we get good support and features added what a small-medium business is looking for.
