JavaMail API は、Java クライアント アプリケーションが包括的な電子メールおよびメッセージング機能を実行できるように設計された、プラットフォームやプロトコルに依存しない堅牢なフレームワークです。この API は、トランザクション電子メール システムで作成されたさまざまなオブジェクトを表す抽象クラスを備えた汎用インターフェイスを提供します。これは、信頼性と広範な機能が最重要であるエンタープライズレベルのアプリケーションに特に役立ちます。
長所:
よく構造化され、広く採用されている:
JavaMail API は、その堅牢な構造と、特にエンタープライズ環境で広く使用されていることで知られています。
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
message.setSubject("This is the email subject");
message.setText("This is the email body");
Multipart multipart = new MimeMultipart();
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText("This is the email body");
multipart.addBodyPart(messageBodyPart);
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource("path/to/attachment.txt");
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName("attachment.txt");
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);

方法 2: 電子メール通知に単純な Java メールを使用する
概要：
Simple Java Mail は、Java で SMTP 電子メールを送信するプロセスを簡素化するように設計された、使いやすいメール ライブラリです。これは JavaMail API のラッパーとして機能し、基礎となる API の複雑さを軽減することで電子メール送信プロセスを合理化します。
HTML コンテンツ、画像、添付ファイルのサポートを提供し、複数の受信者に同時に電子メールを送信できます。
短所:
限定的なコミュニティサポート:
Simple Java Mail のコミュニティ サポートは、JavaMail API に比べて小規模です。
実装手順:
ステップ 1: HTML と添付ファイルを含む電子メール オブジェクトの作成
Email email = EmailBuilder.startingBlank()
.from("From", "from@example.com")
.to("1st Receiver", "rec1@example.com")
.to("2nd Receiver", "rec2@example.com")
.withSubject("Enhanced Email with HTML and Attachments")
.withHTMLText("<html><body><h1>Hello!</h1><p>This is an enhanced email with HTML content.</p></body></html>")
.withAttachment("path/to/attachment.txt")
.buildEmail();
Manages the entire notification lifecycle without heavy reliance on the engineering team. Integrate the JAVA SDK once, and the product team can handle the rest.
Intelligent Routing:
Implements intelligent cross-channel flows across providers without requiring technical dependencies.
In-App SDK:
Provides a developer-ready in-app layer for both web and mobile applications.
Granular Template Management:
Features an intuitive drag & drop editor for designing templates, offering superior control over content.
Powerful Workspace:
Manages multiple projects with distinct integrations, workflows, and templates within each workspace.
Unified Analytics:
Provides a unified view of cross-channel analytics, enabling data-driven decision-making.
Smart Automation:
Automates synchronization, refreshing, and notification triggers to streamline operations.
Scalability:
Automates scalability, ensuring a hassle-free experience.
Cons:
Cost Considerations:
Managing multiple notification channels may incur costs.
*Monthly Notification Limit:*
Though SuprSend provides 10k notifications free every month, which resets every month, you can also buy credits.
Limits:**
There may be restrictions on the number of notifications per month.
Implementation Steps:
Step 1: Integrating the JAVA SDK
Install the SuprSend JAVA SDK:
Add the SDK to your JAVA project via Maven or Gradle.
Step 2: Configuring the API Key and Workspace Secret
Set Up Configuration:
Obtain the API key and workspace secret from your SuprSend account and configure them in your JAVA project.
Step 3: Creating and Sending Notifications
Send Notifications via JAVA SDK:
Use the SDK to send notifications, specifying the required channel (email, SMS, push, etc.) and the content.
import com.suprsend.Notification;
import com.suprsend.NotificationBuilder;
import com.suprsend.SuprSendClient;
public class SendNotification {
public static void main(String[] args) {
// Initialize the SuprSendClient with API key and Workspace Secret
SuprSendClient client = new SuprSendClient("your_api_key", "your_workspace_secret");
// Build the notification
Notification notification = NotificationBuilder.startingBlank()
.withRecipientEmail("recipient@example.com")
.withRecipientSMS("recipient_phone_number")
.withSubject("Notification Subject")
.withHTMLBody("<html><body><h1>Hello!</h1><p>This is a multichannel notification.</p></body></html>")
.build();
// Send the notification
client.sendNotification(notification);
}
}

Complete Code Example with JAVA SDK:
import com.suprsend.Notification;
import com.suprsend.NotificationBuilder;
import com.suprsend.SuprSendClient;
public class SuprSendExample {
public static void main(String[] args) {
// Initialize the SuprSendClient with API key and Workspace Secret
SuprSendClient client = new SuprSendClient("your_api_key", "your_workspace_secret");
// Create the notification
Notification notification = NotificationBuilder.startingBlank()
.withRecipientEmail("receiver@example.com")
.withSubject("Subject of the Notification")
.withHTMLBody("<html><body><h1>Hello!</h1><p>This is a notification from SuprSend.</p></body></html>")
.withAttachment("path/to/attachment.txt")
.build();
// Send the notification
client.sendNotification(notification);
}
}

These methods offer a comprehensive guide to sending email notifications using Java, with varying levels of complexity and integration capabilities to suit different needs and scenarios.
You may want to check out other SuprSend SDKs too. Consider giving us a star after usage. It's free and open.
Following example shows a sample request for triggering a workflow.
It triggers a notification to a user with id: distinct_id,
email: user@example.com & androidpush(fcm-token): __android_push_fcm_token__
using template purchase-made and notification_category system
from suprsend import Workflow

suprsend-node-sdk
Official SuprSend SDK for Node.js
suprsend-node-sdk
This package can be included in a node project to easily integrate with SuprSend platform.
It is a unified API to trigger workflow and doesn't require user creation before hand. If you are using our frontend SDK's to configure notifications and passing events and user properties from third-party data platforms like Segment, then event-based trigger would be a better choice.
