Hi surfertim
the smtp2go user is the gmail( hanluu@gmail.com) address or just user name, because i saw my smtp2go account show the user name (hanluu).thanks
I use the email address I registered with, but it must be base64 encoded.
Same with the password. Base64 encoded.
email sent.
thank you very much
i just change my user name ''hanluu'' into email address then BOOM. I GOT MAIL. THANKS AGAIN.
can you show me how to add a float switch to trigger the email? thank you.
I suppose you got the code here.
http://playground.arduino.cc/Code/Email
If so, in the second example at line 37
// replace this
if(inChar == 'e')
// with something like this
if(triggerPin == HIGH)
Hi.
Can you fix this code to send only 1 email when it trigger the sensor,right now when sensor trigger it send alot of mail. thank you.

Take a look at the "BlinkWithoutDelay" example included with the IDE. That should give you a way to prevent multiple sends.
Hello,
Anyone can help me how to data sent to our Gmail account using Arduino and ESP8266(temperature and humidity) could u please send an anyone a sample code.
This is a very useful thread, thanks to all. I got stuck with an error message saying that I wasn't allowed to send messages to SMTP2GO as I didn't have a senders domain. This is apparently a new security feature of SMTP2GO. Here's the steps to take to get it working:
- Create account at https://www.smtp2go.com/
- Add your email address as a user. Note that each user has their own passwords (separate to the admin account created above).
- To get around the recent issue of needing to have your own sender domain, which is a problem if you want to use say a gmail or ISP issued email address: Make contact with SMTP2GO Support and explain your use case, and they will adjust your account appropriately. This way you can keep Sender Domains blank. If you try and enter a sender domain that you don’t own, you’ll receive the error message “The domain you have entered is not allowed. Please note that you must have control of the DNS of any domain that you add.” (To check if this issue is occurring, open the serial monitor before code execution, and after “235 Authentication Succeeded” you will see an error “That user is not allowed to send”).
- Restrict senders to your chosen email addresses – this provides some level of security against spammers.
- Incorporate the code at Arduino - SMTP2GO into your Arduino sketch.
- The username and password must be sent using base64 encoding by the Arduino to SMTP2GO. You can use https://www.base64encode.org/ (amongst other sites) to do the encodes. (To check if you got the password right, open the serial monitor before code execution and look for “Sending Password”. The next line should say “235 Authentication succeeded”. Otherwise, check you've got the right password and done the base64 encoding correctly).
