Email sending limits

March 14, 2022Topics: Account Management.

Some criminals profit from sending emails with viruses or with scams to innocent people. Their success depends on sending out as many emails as they can. Their success depends on the email arriving on the Inbox, too as the ability to send an email and have it go to the receivers inbox, without going to SPAM, is valuable.

We take our deliverability and reputation seriously, therefore we had to place sending limits on our platform to prevent these unsolicited emails from being sent by nefarious actors.

This solution is constantly being refined and new methods are constantly developed to further reduce the chance of malicious emails of arriving in our users’ inboxes.


10 per hour
240 per day
10MB Max Attachment Size
We do not allow sending file types associated with malware.
Emails between CTemplar users: unlimited
Recipients per message TO: 10, CC: 10, BCC: 1

Note: We limit BCC to “1” on free accounts because it is the most common tool used by those sending spam.


100 emails per hour
2000 emails per day
50MB Max Attachment Size
Emails between CTemplar users: unlimited
Recipients per message: TO: 20, CC: 20, BCC: 20


Unlimited emails to non-CTemplar users and CTemplar users.
50MB Max Attachment Size
Recipients per message: TO: 20, CC: 20, BCC: 20

What happens when the email limit is reached?

If limit is exceeded, an error will be displayed and an email notification will be sent. The message will also be saved as a draft. Limits per hour / day are applied over a rolling 1-hour / 24-hour period. As soon as the period ends, you will be able to send email.

We are all friends who built this service because we love it. We are the only secure email service that is not funded by a Government or global corporation because email services like this cost a lot of money to operate. Our goal is to earn enough to be able to pay for the monthly server costs.
