Issue with Server Overload When Sending Emails to Large Segments in Mautic 5.0.3

Hello Mautic Community,

I am encountering a problem with my Mautic 5.0.3 setup when trying to send emails to a large segment of 17,000 contacts from the dashboard. The issue is that the server crashes because the messenger_messages table gets filled up too quickly when I click to send the email before the consume command can process and clean up the table.

Is there a way to limit the batch size of messages that can be sent to a segment over a period of time directly from the dashboard? I am looking for a solution to avoid server overload and ensure smooth email sending operations.

I have already configured cron jobs for processing messages, but the problem specifically arises when initiating the email send from the dashboard interface.

Any advice or recommendations on how to handle this would be greatly appreciated.

Thank you!
