Email Returned Error: Speed Limit Exceeded

If your email keeps getting returned with the message "Speed Limit Exceeded" or a 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, make sure to include a detailed explanation, and we will gladly do our best to accommodate your needs.

For further assistance, you may contact our Chat Support or Phone Support via 888-401-4678. You may also refer to our Knowledge Base articles to help answer common questions and guide you through various setup, configuration, and troubleshooting steps.
