Emails sent using campaigns

[knsmanish]

Your software
My Mautic version is: 3.3.3
My PHP version is: 7.3.30
My Database type and version is: MariaDB v5.5.68

Your problem
My problem is:
This is how the email queue handling is currently setup in my Mautic instance.

This is the cron job setup on the VPS to send mails.

My understanding (or the intended behavior) is to send 50 emails in one blast, wait for 3 minutes before sending another set of 50. Also for the cron, to check every minute if any email is waiting to be sent, and send it.

Contrary to the expectations, when i setup a campaign to send the emails, it shows it sent to all the 8k+ contacts in one go. Now if have no way to know if the mails were sent in the queue or in a single blast. Also, if all the emails were sent out in one blast, then how exactly to stagger these options for the intended behavior.

These errors are showing in the log:
These are not errors, however from the very beginning of the campaign, this has been showing to have been sent to everybody in one go.

Also, if all the emails got sent in one go, I think many of them would not have gotten sent to the recipients as they would have expired after 5 days. Is there a way to know of such cases so that the mailer could be sent to remaining contacts?

Steps I have tried to fix the problem:
I have tried all in my understanding to get it working as per the expectations, but in vain.

Hourly Limits

use –message-limit XX in your cron and replace the XX with the number of emails you want to send. If you are using queue then swiftmailer:spool:send --message-limit=xx specifies how many emails per cron are sent to your delivery server for processing (actual sending)

@Hourly Limits

swiftmailer:spool:send --message-limit=xx

thank you for your help. I had read this earlier. I have also now applied it to my instance and waiting on to see if it worked. I have another question though, if at all I have to setup a cron with these limits, what is the point of the configuration options in the Mautic email settings panel?

Its my understanding that it controls the speed of queueing and not actual dispatch to your email server.

The confusing part is that the stats show emails have been “Sent” upon queue but not actually sent until the queue is processed.
