Hello , i am trying to build a PM that sends mails to users(81 in total), i put delay between the emails 25 seconds , but after some repetitions (33,42,72) random each time PM stops with the error : Failed to send email

Is there a limit of email that a sigle PM can send ? or something

Feels more like a limitation on the mail server side. I suggest to contact the mail server admins.

Did you check the logs if there are any details of the error? random time failures can be due to memory/server related issues. Can't guess the exact cause here.

A suggestion I can make is instead of using 25 seconds delays, Can you configure a process with just email node in it and pass the users one by one using MNI on a start process smart service. This way the emails will go asynchronously and perform better in general.

There’s no hard limit on emails per process, I suggest you check the system logs for exact errors.

Here are two recommendations to help address the issue:

1) I recommend contacting your mail server administrators to check for any SMTP-related restrictions or issues.

2) Instead of using "Run all instances at the same time" use "Run instances one at a time". This way we can avoid the connection to SMTP server getting exhausted. Or instead of MNI, create your own loop.
