This Java module allows you to quickly and easily send emails through SendGrid using Java.
// SendGridExample.java
import com.sendgrid.*;
public class SendGridExample {
public static void main(String[] args) {
SendGrid sendgrid = new SendGrid("SENDGRID USERNAME", "SENDGRID_PASSWORD");
SendGrid.Email email = new SendGrid.Email();
email.addTo("[email protected]");
email.setFrom("[email protected]");
email.setSubject("Hello World");
email.setText("My first email with SendGrid Java!");
try {
SendGrid.Response response = sendgrid.send(email);
System.out.println(response.getMessage());
}
catch (SendGridException e) {
System.err.println(e);
}
}
}Compile and run this example with
$ javac -classpath sendgrid-1.2.1-jar.jar:. SendGridExample.java && java -classpath sendgrid-1.2.1-jar.jar:. SendGridExampleChoose your installation method - Maven w/ Gradle (recommended) or Jar file.
Add the following to your build.gradle file in the root of your project.
...
dependencies {
...
compile 'com.sendgrid:sendgrid-java:1.2.1'
}
repositories {
mavenCentral()
}
...Then import the library - in the file appropriate to your Java project.
import com.sendgrid.SendGrid;You can just drop the jar file in. It's a fat jar - it has all the dependencies built in.
import com.sendgrid.*;To begin using this library, initialize the SendGrid object with your SendGrid credentials.
import com.sendgrid.SendGrid;
SendGrid sendgrid = new SendGrid("sendgrid_username", "sendgrid_password");Add your message details.
Email email = new Email();
email.addTo("[email protected]");
email.addToName("Example Guy");
email.setFrom("[email protected]");
email.setSubject("Hello World");
email.setText("My first email through SendGrid");Send it.
sendgrid.send(email);email.addTo("[email protected]");
// or
email.setTo(["[email protected]"]);email.setFrom("[email protected]");email.setFromName("Other Dude");email.setReplyTo("[email protected]");email.setSubject("Hello World");email.setText("This is some text of the email.");email.setHtml("<h1>My first email through SendGrid");email.addAttachment("text.txt", "contents");
// or
email.addAttachment("image.png", new File("./image.png"));
// or
email.addAttachment("text.txt", new InputStream(new File("./file.txt")));// First, add an attachment
email.addAttachment("image.png", new File("./image.png"));
// Map the name of the attachment to an ID
email.addContentId("image.png", "ID_IN_HTML")
// Map the ID in the HTML
email.setHtml("<html><body>TEXT BEFORE IMAGE<img src=\"cid:ID_IN_HTML\"></img>AFTER IMAGE</body></html>")SendGrid sendgrid = new SendGrid("SENDGRID USERNAME", "SENDGRID_PASSWORD");
HttpHost proxy = new HttpHost("server", 3128);
CloseableHttpClient http = HttpClientBuilder.create().setProxy(proxy).setUserAgent("sendgrid/" + sendgrid.getVersion() + ";java").build();
sendgrid.setClient(http);The mail object extends the SMTPAPI object which is found in STMAPI-Java.

SendGrid sendgrid = new SendGrid("sendgrid_username", "sendgrid_password");
sendgrid.addTo("[email protected]");
...
sendgrid.addFilter("bcc", "enabled", 1);
sendgrid.addFilter("bcc", "email", "[email protected]");- Fork it
- Create your feature branch (
git checkout -b my-new-feature) - Commit your changes (
git commit -am 'Added some feature') - Push to the branch (
git push origin my-new-feature) - Create new Pull Request
The existing tests in the src/test directory can be run using gradle with the following command:
$ ./gradlew test -i$ ./gradlew buildWe have an example app using this library. This can be helpful to get a grasp on implementing it in your own app.
