I have a email marketing system, would I be able to send bulk emails via the email account?
The limit for cPanel account 350 emails per hour. We no longer raise the limit with dedicated IPs as the volume of email being sent was affecting the web server performance.
If you need to send more email your can ratelimit your script so it sends in batches of 350 (or less) /hour. A further option might be a VPS.
