Email Returned Error: Speed Limit Exceeded

If your email keeps getting returned with the message "Speed Limit Exceeded" or similar message, then you have exceeded your hourly limit for outbound mail.

There is a default limit on all hosting accounts of 150 email messages sent per hour. This is a policy to help control spam on the internet and does not apply to your inbound email. You can receive as many emails as will fit in the email account's quota.

If you have a legitimate need to send more than 150 messages per hour, please contact us via phone or live chat. Include a detailed explanation and we will gladly do our best to accommodate your needs.
