How to Send Emails in Spring Boot

Spring Boot provides an easy way to send emails using JavaMailSender and Spring Boot Starter Mail.

Spring Boot simplifies email sending by using the JavaMail API. The key components involved are:

• JavaMailSender: The main interface for sending emails.
• SimpleMailMessage: Used for sending plain text emails.
• MimeMessageHelper: Used for sending rich content emails, including attachments and HTML.

Step 1: Add Dependencies

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

This includes JavaMailSender, which is required for sending emails.

Step 2: Configure SMTP Settings

Configure the mail server settings in application.properties (for Gmail SMT

spring.mail.host=smtp.gmail.com
spring.mail.port=587
[email protected]
spring.mail.password=your-email-password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
