Is there a limit on the number of messages that I can send?
Free accounts are limited to 10 message sends to non-paid users over the account’s lifetime. To continue sending secure emails without restrictions, free users can upgrade to a Business account.
Business accounts have no limit on the number of messages sent via the web portal or our client applications. However, standard Business accounts are restricted to 300 sends per month through our SMTP service.
