The ability to send multiple pages at once via email is great! I do not like that emails are required instead of just being able to use an app but maybe it’s because we have had our account set up so long (over 5 years) where many customers don't understand how apps work compared to using their phone number/email address etc.
It's hard sometimes when you need something very quickly in your business without waiting days if someone else sends out one page first then comes back after hours later saying "I sent my info already!" But as far as speed goes its definitely better than sending them by snail mail which takes forever too!!
