Could you please help me, I want to know if you can send more than one email to the same recipient but with a different subjet is for an alarm that senses two variables.

because I tried it but I could not. What should I do?

Have you read the documentation?

It shows how to do this, but also reminds users that there is a limit of 1 email every 15 seconds.



I would say follow @PeteKnight’s guidance, and just send the second one after 15 seconds have passed.

Maybe this will be a bit more help:"", "Subject", "Your message goes here");
timer.setTimeout(16000L, []() {  // Run after 16seconds second
"", "Second Subject", "Your Other message goes here");
           });  // END Timer Function

Thanks for this information, is very useful
