as stated here: www.limesurvey.org/manual/Global_settings#Email_settings
smtp email send method is manual.
can i automate it using cron?
found this: www.limesurvey.org/manual/Cron
but i;m not sure how to use it for smtp
in a workcase of 6000 participants in a 300email per hour batch send, can be a problem
thanx

Maybe this script here can help you: www.limesurvey-templates.com/limesurvey-...vv9lasvbhir2lfuekd27

(I am in no way affiliated with the shop and I have not tested it, I just know that it exists)

i'd prefer a hint to write my own crontab entries, but that can also do the trick. thanx!

sorry, can't help there.

Just published this morning www.limesurvey.org/index.php?option=com_...dmailcron&Itemid=729

But in forum since 6 month : www.limesurvey.org/forum/plugins/104454-...reminder-via-php-cli

your script can work with smtp?

Work in any mail system configurated in LimeSurvey, try it.

And it's GPL : then can be fixed/updated/ etc ....

For example : have an option to send X email each time (and not more) can be a good isea.

tried sendMailCron plugin. i set it up amd tries to run the cron command but failed. my output:
php /home/prorataonlinesurveys/public_html/application/commands/console.php plugin cron --interval=20

The following commands are available:

- webapp
- wipe

To see individual command help, use the following:
/home/prorataonlinesurveys/public_html/application/commands/console.php help <command-name>
i'm using version 2.56.1+161118. also, do i put the command in crontab?

It's not the good place for report this bugh.

But here : seems not related with plugin, more with console.php plugin cron
