**Your software** My Mautic version is: V5.0.0-rc2 My PHP version is: 8.1 My Database type and version is: MariadDB 10.6 When I did the original install, on Step 2 I was asked “How should emails be spooled and delivered?” Options being “Send Immediately” or “Queue”. I had selected “Send Immediately” and proceeded with the install. Now however, after reading some posts on deliverability, I have determined that it’s in my best interest to use the Queue feature to start with. Everything I can find in the documentation and forums say to go to **Configuration → Email Settings → How should email be handled?** and change it to Queue. But I do not have that setting anywhere in M5. How do I change this? ---

Looked at that and I don’t think that’s it either. Not sure as there’s nothing in the docs about that. I did find in the docs this morning that it’s saying to switch to queued sending all you need to do is set a cron job… `bin/console messenger:consume email_transport` If that’s the case, then what is sending them now? the 3 cron jobs I have running are: ```auto bin/console mautic:segments:update bin/console mautic:campaigns:update bin/console mautic:campaigns:trigger ``` Do you know which one of those I would need to remove when adding in the one required for queuing in order to prevent the immediate sending? Thanks. ---

I am also not understanding how that one cron job alone determines the “rate” in which the queued emails are sent out (i.e. say I only want to send 100/hour and the cron job is running every 5 minutes, that would be 8 emails per cron execution). ---

Is there anyone at all in the community that can assist me in getting M5 properly setup to send emails via queue? ---

Thanks for the help @marko008. It’s not working just yet. I’m getting errors from the cron jobs. When I look at the logs, the first error I get is that `The "--batch-limit" option does not exist.` I tried it on both command of `messenger:consume email_transport` and then `messenger:consume email` Also, when I don’t have the --batch-limit= on it, I get the error message that `The receiver "email_transport" does not exist.` ---

Hi guys, I have the same issue. I can’t find a way to limit the number of emails sent every time a cron job runs. Does anyone have an idea ? ---

I found more information. The syntax is not correct. It would be `/bin/console messenger:consume email --limit=20` which would send 20 emails each time a cron job runs. For more options about messenger:consume, you can run : `php /var/www/html/bin/console messenger:consume -- help` I got rid of the errors you mentioned but I still can’t send emails with my campaigns, although Mautic marks the emails as sent. I have the email configured in the “Email Settings”, tested, OK. In “Queue Setting”, Emails are configured to “Doctrine” and “Default” for the host. And I have a cron job that runs every 10 minutes : \*/1 \* \* \* \* php /var/www/html/bin/console messenger:consume email --limit=1 What’s the problem? By checking the log i can see the errors are gone. ---

To debug, I recommend to comment out your cron commands and launch everything directly from terminal. 1. Make sure the particular email is “published” and date is set to a moment in past: ![2024-02-22 at 13.37](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/c/c09700fbafcc26516d81c37a0768ddd7ab5b75d7.jpeg) 1. Make sure your “queue” settings are set to doctrine 2. run emails generator ```auto php -d memory_limit=-1 ./bin/console mautic:broadcasts:send --batch=30 --limit=2000 --id=[YOUR-EMAIL-ID] ``` in terminal, from mautic working dir (note that you need to get your email id from mautic emails list - this arg helps to isolate sending and debugging for 1 particular campaign) This will start feeding your queue with generated emails. If the process exists fast - this means you have a problem with your email generation setup. If it starts working - you will see it, it takes many seconds. 1. Run actual email sending (you can start another terminal instance for this): ```auto php ./bin/console messenger:consume email --memory-limit=8280M -vv ``` ![2024-02-22 at 13.45](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/f/f7b7cd02804da213a61748a6e449bdfad41510ef.png) So, you need _two_ processes running when you want to send queued email campaign: first one is generating emails and putting it into queue; another one is working on the queue. If it works from terminal, you can start moving these commands either into crontab or daemon like supervisorctl [(my preferred method).](https://forum.mautic.org/t/messenger-consume-redis-concurrency-for-better-queued-emails-performance-error-could-not-acknowledge-redis-message/30855/7) ---

Thank you so much! I followed your suggestions and I was finally able to troubleshoot and set my desired limit rate! Emails are now sent properly. Awesome! ---

@jet1 Thank you for that! When running from CLI, everything seems to work. The only thing I’m noticing is that the `php ./bin/console messenger:consume email -vv` doesn’t exit when you run it. This causes a problem when I have it running via cron, as I end up with many many instances of it running until the server bogs down to the point of locking up the server. What do I need to do to get it to exit after each execution? Also, the `-vv` isn’t reporting anything to the console. Is that normal? ---

`messenger:consume` is designed to be a long-lived process so it can be run via `supervisortctl` or `systemd` (restarted from time to time, e.g. via `--memory-limit=1280M`. you can condition it to work inside cron via `--time-limit=360` arg or/and `--limit=10` (amount of emails) as well. to see all available options, run `./bin/console help messenger:consume` ---

I just thought of 1 more question. All this has been done with testing Broadcast emails. What about Campaign emails? Those have been sending out immediately even without the `bin/console mautic:broadcasts:send` and `bin/console messenger:consume email` commands. It’s probably not as critical in my situation as the likelihood of a campaign triggering that many emails at once is fairly rare, but would be nice to understand what would be needed. ---

Mautic brodcast send is processed in batches how often it gets called it depends on your cron config. ---
