How do I breakline in MATLAB emails?

Hey, just a simple question that I cant find the answer :(

How do I break lines in MATLAB emails??

I tried with <br> and \n.

This is an screenshot of what I'm talking about

And the String is:

alertBody = "El sistema de monitoreo no ha obtenido ningun dato del Arduino en los ultimos 10 minutos.<br> Se recomienda verificar el dispositivo para su correcto funcionamiento.<br><br>\n\n\n1. Verifique que el Arduino esté con corriente<br>2. Verifique que la conexión Ethernet esté correcta y las luces esten encendidas.<br>3. Si ninguna de estas opciones solucionó el problema, presione el botón rojo ubicado en el Arduino<br>Canal de Información: https://thingspeak.com/channels/970650";

I appreciate any help, thanks and have a nice day!

Try using sprintf() with single quotes:

alertBody = sprintf('El sistema de monitoreo no ha obtenido ningun dato del Arduino en los ultimos 10 minutos.<br> Se recomienda verificar el dispositivo para su correcto funcionamiento.<br><br>\n\n\n1. Verifique que el Arduino esté con corriente<br>2. Verifique que la conexión Ethernet esté correcta y las luces esten encendidas.<br>3. Si ninguna de estas opciones solucionó el problema, presione el botón rojo ubicado en el Arduino<br>Canal de Información: https://thingspeak.com/channels/970650');

I don't think the <br> would be needed if the \n work.

Try

alertBody = sprintf('El sistema de monitoreo no ha obtenido ningun dato del Arduino en los ultimos 10 minutos.\r\n Se recomienda verificar el dispositivo para su correcto funcionamiento. \r\n 1. Verifique que el Arduino esté con corriente\r\n 2. Verifique que la conexión Ethernet esté correcta y las luces esten encendidas.\r\n 3. Si ninguna de estas opciones solucionó el problema, presione el botón rojo ubicado en el Arduino\r\n Canal de Información: https://thingspeak.com/channels/970650');

It doesnt work :(

I don't see any \n or <br> in there, so what exactly didn't work? Are there other characters in there you don't want? Or some formatting is not what you desire? Saying "It doesn't work" is virtually useless. What I hear is "It did not work but I don't want to bother to tell you why it didn't work or ask any follow-up question, so I'm just not going to worry about it anymore and will use it as-is."

[Benjamin Cortez]

You don't see any \n or <br> because the program just ignore it. If I do a display of the alertBody String, shows this in the output:

Which tells me that the problem is not the code.

But the email shows the text without breaklines.

Sorry for the poor explanation, and have a nice day!

So are we done here? Can you get the layout you want using \n in the right places?

Update: As of April 2020, the ThingSpeak Alerts API now supports inclusion of tabs, spaces, and newlines in the alert body text.

---------------------------

Old Answer:

ThingSpeak Alerts do not currently support formatting characters like newlines and tabs. The characters are not removed, but do not display as expected in the email. I have created an enhancement request to add this capability.

Thanks for the answer! Have a nice day.

PD: Another thing, Can you ask for HTML support? Like link images with <img src=""> and stuff like that.
