How many contacts or customers can I have in my account to whom I send documents?

How many clients can I have? What is the fee for each client account?

There is no limit to the number of customers/clients you can have. 

In fact, the point of using Encyro is to make your customers happier and save time managing email attachments, so you can grow the number of your clients. 

There is no additional fee for each client account. Each client receives a free Encyro Essentials membership if they opt to sign up. Clients may also receive your messages without signing up for an Encyro account.
