Can I specify the number of emails

Your software
My Mautic version is: 5.0.4
My PHP version is: 8.1.28
My Database type and version is: 10.6.17-MariaDB-cll-lve-log

My problem is:
How can I specify the number of emails or the time intervals between each email to ensure that the email does not reach spam?

Mautic sends emails via cron command.

It has a limit parameter which controls how many emails mautic sends in one batch.

Via cron you configure how often your script runs. It can run every minute, every 5 minutes or any arbitrary interval you like.
