We are moving towards the World of Internet of Things (IoT). This technology plays a very important role in the Electronics and Embedded system. Sending an Email from any Microcontroller or Embedded system is very basic thing, which is required in IoT. So in this article, we will learn “How to send an Email using Wi-Fi and Arduino”.
For sending Email via Wi-Fi module and Arduino, first of all we need to have an Email account. So user can create email account at smtp2go.com. After signup, remember your new email address and password.
You can also learn How to Call and Message using Arduino.
We can understand the whole process in below Steps:
Step 1: First arrange all the required Components.
- Arduino UNO
- ESP8266 Wi-Fi module
- USB Cable
- Laptop
- 16x2 LCD (optional)
- 10K POT (optional)
- Power supply
- Connecting wires
Wi-Fi Module ESP8266:
Step 2: In this step we will connect ESP8266 Wi-Fi module with Arduino and give it power supply from 3.3v pin of Arduino.
Step 3: In this step, we need to sign-up for Email address and Password (smtp2go.com). smtp2go.com provides the email services, to send the emails using outgoing email server.
Step 4: We will need Username and Password in base64 encoded format with utf-8 character set. For converting the Email and Password in base64 encoded format use below given link. Keep the encoded username and password handy, we need it in our program to login at smtp2go.com.
Step 5: Now start writing code for sending Email. ‘Programming Explanation’ and Code is given at the end.
Circuit Explanation:
Circuit is very simple, for this project we only need Arduino and ESP8266 Wi-Fi module. A 16x2 LCD is also connected for displaying the status messages. This LCD is optional. ESP8266’s Vcc and GND pins are directly connected to 3.3V and GND of Arduino and CH_PD is also connected with 3.3V.
Tx and Rx pins of ESP8266 are directly connected to pin 2 and 3 of Arduino. And Pin 2 of Arduino is also shorted with Tx pin (Pin 1) of Arduino. This pin is shorted for displaying response of ESP8266 directly on Serial monitor of Arduino. Software Serial Library is used to allow serial communication on pin 2 and 3 of Arduino.
Note: For watching the response of ESP8266 on Serial Monitor, don’t initialise the Serial.begin(9600) function.
Programming Explanation:
1. In programming part first we include libraries and define pins for LCD & software serial communication. By default Pin 0 and 1 of Arduino are used for serial communication but by using SoftwareSerial library, we can allow serial communication on other digital pins of the Arduino.
2. void connect_wifi(String cmd, int t) Function is defined to Connect the Wi-Fi module to the Internet.
void connect_wifi(String cmd, int t)
{
int temp=0,i=0;
while(1)
{
Serial1.println(cmd);
while(Serial1.available())
{
if(Serial1.find("OK"))
... .... ....
... .....
3. After it connect module to SMTP server by using given commands:
lcd.print("Configuring Email..");
Serial1.println("AT+CIPSTART=4,\"TCP\",\"mail.smtp2go.com\",2525");
delay(2000);
Serial1.println("AT+CIPSEND=4,20");
delay(2000);
Serial1.println("EHLO 192.168.1.123");
delay(2000);
Serial1.println("AT+CIPSEND=4,12");
Note: Many email servers will not accept email from a non-commercial, dhcp-issued ip address.
4. Now we will try to Login at smtp2go.co, using the base64 encoded User name and password, which we have derived in Step 4 above.
lcd.print("Try To Login.....");
Serial1.println("AUTH LOGIN");
delay(2000);
Serial1.println("AT+CIPSEND=4,30");
delay(2000);
Serial1.println("c2FkZGFtNDIwMUBnbWFpbC5jb20="); //base64 encoded username
delay(2000);
Serial1.println("AT+CIPSEND=4,18");
delay(2000);
Serial1.println("Y2lyY3VpdDQyMDE="); //base64 encoded password
5. After this, enter your main message that user want to send. And send this email by ending line (sending) ‘.’
Serial1.println("Testing Success");
delay(2000);
Serial1.println("AT+CIPSEND=4,3");
delay(2000);
Serial1.println('.');
delay(10000);
Serial1.println("AT+CIPSEND=4,6");
delay(2000);
Serial1.println("QUIT");
... .....
.......
Other functions and Code are self-explanatory and easy to understand.

I don't know why code is showing error in the line connect_wifi("AT+CWJAP=\"1st floor\",\"muda1884\"",7000);
Here my code is connect_wifi("Android AP_2704",kavita123); telling "my password" was not declared in this scope.
Please help me out.

Hi!!! How did you solve this
Hi!!! How did you solve this problem?
how to watch on the serial monitor?
Hi!
Having fun working this through. I don't have an LCD, and you mention "Note: For watching the response of ESP8266 on Serial Monitor, don’t initialise the Serial.begin(9600) function.". Can someone explain how to do that in the code?
MANY thanks!
Means you should not use
Means you should not use default Rx and Tx pins (0 and 1) of Arduino for serial communication, instead use 2 and 3 pin as Rx Tx using SoftwareSerial.h Library and short the Pin 1 and 2 to get the response on Serial Monitor as done in this tutorial.
Hi,
Hi,
thanks for writing this tutorial. But i got a problem.
Im always stuck on "Getting IP Add."
The eps is visible in my router overview and also got an ip adress.
AT+CIFSR
192.168.4.1
192.168.178.48
OK
but it wont stop asking for a ip adress.
What am i doing wrong?
Thank you sir.. I can confirm
Thank you sir.. I can confirm that this is working. Simple and easy..just follow the steps. I set it up to sent me an email when there is an alarm trigger at home.I wrote the commands in an progmem array and used a for function to call them so they dont use ram.The only problem is that the email applications dont refresh/synchronise on smartphones to often.
Problem
Very goog job ......BUT....
if i give the AT command by hand for the '.' (DOT, for terminate the text of the email) in the serial monitor works and send me an email
BUT if i put this in the code doesn't work see below....please help me thanks a lot
Serial1.println("AT+CIPSEND=3");
delay(2000);
Serial1.println('.');
Looping the same output
OK
AT+CIFSR
192.168.4.1
192.168.1.3
OK

Email is not received
Hi,
Thanks for this tutoriel
I made an account in smtp2go and I use AT commands to send an email with my arduino uno and my esp8266 module
All steps are successfully done, but when I check my gmail account, I cannot find any email (even in Spams)
Is this issue related to only gmail or there is another problem ?
hi i have done the connection
hi i have done the connection according to ur circuit only and i have added my base encoded paswword and email id but still when i upload the code the initial commands for 9600 bps is not shown in the serial terminal
SMTP2GO not available
when I try to create an account at the SMTP2GO site it says that it is not available in my country..are there any other alternatives which have a very close functionality to this one?
Hi, nice project.
Hi, nice project.
Well, i've been trying to make this work for a few days, but i got this problem. Everything works fine until this point.

Do you know what it could be?
Thank you a lot
Hi,
Hi,
I am unable to load the code from arduino ide to esp8266
Sketch uses 232,505 bytes (53%) of program storage space. Maximum is 434,160 bytes.
Global variables use 32,504 bytes (39%) of dynamic memory, leaving 49,416 bytes for local variables. Maximum is 81,920 bytes.

hi syukran. i having the same
hi syukran. i having the same problem too.. have you solved the problem? If yes can you share me how to solve it?
Configure Arduino IDE
Guys you have to prepare the Arduino IDE before you can compile the ESP8266 programs on Arduino IDE.

Can I email a photo in this process?
Thank you so much for such a useful project demonstration.Now,using this exact process,can I email a photo stored in my sd card attached to the arduino board?
If yes,please give related information....Thanks a lot....
No, Arduino is not powerful
No, Arduino is not powerful enough to process pictures

What is this IP address ??
IS it network Ip or esp8266 ip?
Hello Saddam,
Thank you for posting this project.
I'm new to the ESP8266 and ARDUINO UNO, Can you please share the step by step procedure followed by you during the project.
Thanks in advance
