 Good morning people!
 
 I am new in Arduino word and I am using with great success the EmailSender library.
 
 Thanks a lot for your work!
 
 Now I am not success trying to send the value of a variable obtained from the Esp8266 sketch using the simple email sender. (my project do not have SD support).
 
 I need to send a message with a welcome text (like your examples), but including the value of a variable from the sketch routine.
 
 Could someone help me?
 
 Thank you very much and have a nice time.
 
 Greetings.

 Hi Mario,
 
 I put a piece of my Inverter monitor where I send a set of value via mail when there is a problem
 
 EMailSender::EMailMessage message;
 const String sub = F("Inverter error!"); // Here the subject
 message.subject = sub;
 
 const String mp = F("Error on inverter centraline");
 const String ft = (fixedTime)?F("OK"):F("NO");
 const String sd = (sdStarted)?F("OK"):F("NO");
 const String wc = (wifiConnected)?F("OK"):F("NO");
 const String sf = (isFileSaveOK)?F("OK"):F("NO");
 
 // Here the message in html format
 message.message = mp+
 F(" Time fixed: ")+ft+
 F(" SD Initialized: ")+sd+
 F(" Wifi Connecter :P: ")+wc+
 F(" Saving file ok: ")+sf+
 F(" Wrong saving attempts: ")+sdWrongReadNumber;
 
 EMailSender::Response resp = emailSend.send(emailToSend, message);
 The result is
```
Error on inverter centraline
Time fixed: OK
SD Initialized: OK
Wifi Connecter :P: OK
Saving file ok: NO
Wrong saving attempts: 10
```
 Bye Renzo

 Hi Renzo.
 
 Thank you very much for your clear and didactic example.
 It has allowed me to understand in a minute how to solve my problem.
 At the same time, it helps me to see in which area should I focus my study.
 I am very excited.
 Have a nice day.

 Hi Renzo
 
 can you tell me What type of this variable is ( sdWrongReadNumber ) in this code or send to me the code ,
 
 Because I am trying to send, via email, a variable that contains a number, but I was not able, so I tried a byte variable, and also, did it work, because the program considered the code wrong
 
 thank you very much

 Hi Mohammed,
 
 I use this declaration
 
 uint8_t sdWrongReadNumber = 0;
 
 You can find the complete sketch of the Power One aurora Inverter at this link.
 
 GitHub repository of ABB Aurora inverter web interface.
 
 If you need more info, ask.
 
 Bye Renzo
