If you're unable to send email, it could be one of two things:
- Your account was recently Rate Limited due to sending too many emails.
Our email system restricts the number of messages that are sent in a 5-minute interval to 150 messages to prevent spam from harming the reputation of our mail server. This is one method implemented to ensure our mail servers do not get blacklisted by other providers.
This includes messages that are addressed to 150 or more recipients.
If you attempt to send more than this limit, you may be temporarily prevented from sending mail again. You may either wait until noon or midnight for the block to be removed automatically, or you may contact support.
- Your email client may be misconfigured.
