The SMTPClient library allows you to send emails using an ESP8266 microcontroller. It supports sending plain text emails as well as emails with attachments.
- Connect to an SMTP server
- Authenticate using username and password
- Send plain text emails
- Send emails with attachments
- Download the library and place it in the
librariesfolder of your Arduino IDE. - Include the library in your sketch:
#include <ESP8266_SMTPClient.h>Initialize the Client
SMTPClient smtp;
smtp.begin("smtp.example.com", 587);
smtp.setCredentials("your_username", "your_password");Send a Plain Text Email
bool success = smtp.sendMail("[email protected]", "[email protected]", "Subject", "Email body");
if (success) {
Serial.println("Email sent successfully!");
} else {
Serial.println("Failed to send email.");
}Send an Email with Attachment
bool success = smtp.sendMailWithAttachment("[email protected]", "[email protected]", "Subject", "Email body", "/path/to/attachment.txt");
if (success) {
Serial.println("Email with attachment sent successfully!");
} else {
Serial.println("Failed to send email with attachment.");
}
bool begin(const String& server, uint16_t port)
Initialize the SMTP client with the server address and port.
void setCredentials(const String& username, const String& password)
Set the username and password for SMTP authentication.
bool sendMail(const String& sender, const String& recipient, const String& subject, const String& message)
Send a plain text email.
bool sendMailWithAttachment(const String& sender, const String& recipient, const String& subject, const String& message, const String& filePath)
send a email with attachment.
