It depends
If you’ve configured an external dedicated SMTP Service such as Mailgun, SendGrid, Amazon SES, or SendInBlue – then you can send as many emails as you like, depending on your plan with that particular service.
However, if you’re using our Mailgun account, we have a sending limit in place since email sending has a hard cost to us and we need to be careful with scaling costs since we’re giving ZZaZZe to you for free (as a part of ZZ Servers).
The current monthly limit is 2,000.
As we are just launching ZZaZZe, we don’t know how many emails the average member is going to send, so we’ll be monitoring this with the goal of hopefully increasing it once we get a clearer view of the hard costs to us.
