Amazon SES Client

Amazon Simple Email Service (Amazon SES) is a cloud email service for sending and receiving email. This client uses the original SES API (v1), which you still need to manage email receiving, with receipt rules and filters. For sending, AWS recommends the SES API v2, available in the Amazon SES API v2 extension, as new sending features are only added there.

For more information, see the Amazon SES documentation.

The Amazon SES extension is based on AWS Java SDK 2.x. It’s a major rewrite of the 1.x code base that offers two programming models (Blocking & Async).

The Quarkus extension supports two programming models:

  • Blocking access using URL Connection HTTP client (by default), the Apache 5.x HTTP client, the Apache HTTP client (deprecated) or the AWS CRT-based HTTP client

  • Asynchronous programming based on JDK’s CompletableFuture objects and the Netty HTTP client or the AWS CRT-based HTTP client

In this guide, we see how you can get your REST services to use Amazon SES locally and on AWS.

Prerequisites

To complete this guide, you need:

  • JDK 21+ installed with JAVA_HOME configured appropriately

  • an IDE

  • Apache Maven 3.8.1+

  • Docker, to run Amazon SES locally with Dev Services and to run the tests

  • Optionally, GraalVM or Mandrel installed to build a native executable

No AWS account is required: Dev Services and the local Floci container provide everything you need. You only need an AWS account and the AWS Command Line Interface if you want to deploy to AWS.

Start Floci automatically with Dev Services

The easiest way to start working with Amazon SES is to run a local instance using Dev Services. Dev Services starts a Floci container in dev and test modes, and configures the client to use it, so you don’t need an AWS account.

The container listens on a random port, so you never hard-code an endpoint. It is labelled quarkus-dev-service-floci and shared between the Quarkus applications running in dev mode. Refer to Dev Services for Amazon Services for the provider selection, the container configuration and the init scripts.

Start Floci manually

You can also start a Floci container yourself:

docker run --rm --name floci --publish 4566:4566 -d floci/floci:latest-compat

This starts a Floci instance that is accessible on port 4566. Floci exposes all the services it emulates on this single endpoint.

The latest-compat image ships the AWS CLI, already configured to target the local endpoint. Run the provisioning commands of this guide inside the container, with docker exec floci aws …​. You do not need to install or configure the AWS CLI on your host.

You can check the region, the credentials and the endpoint used inside the container:

docker exec floci env | grep AWS_

The CLI uses the region us-east-1, the credentials test / test, and the endpoint http://localhost:4566 seen from inside the container. An application running on the host reaches Floci at http://localhost:4566; an application running in another container must use the container name, for example http://floci:4566, and the containers must share a Docker network.

Solution

The application built here allows sending text emails to the recipients that are verified on AWS SES.

It uses the synchronous client first, then the asynchronous client in Going asynchronous.

We recommend that you follow the instructions in the next sections and create the application step by step. However, you can go right to the completed example.

Clone the Git repository: git clone https://github.com/quarkusio/quarkus-quickstarts.git, or download an archive.

The solution is located in the amazon-ses-quickstart directory.

Walkthrough

Creating the Maven project

First, we need a new project. Create a new project with the following command:

mvn io.quarkus.platform:quarkus-maven-plugin:4.0.0.Beta1:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=amazon-ses-quickstart \
    -DclassName="org.acme.ses.QuarkusSesSyncResource" \
    -Dpath="/sync" \
    -Dextensions="rest-jackson,amazon-ses"
cd amazon-ses-quickstart

This command generates a Maven structure importing the Quarkus REST and Amazon SES Client extensions. After this, the amazon-ses extension has been added to your pom.xml, along with quarkus-rest and quarkus-rest-jackson.

The Amazon SES extensions are a component of the Quarkus platform, and the generated pom.xml already imports their BOM through it, which is the recommended setup.

Due to differing release schedules, the Quarkus platform may not include the latest Quarkus Amazon Services release. If you need features from a newer release, replace the generated quarkus-amazon-services-bom import with the Quarkus Amazon Services BOM:

<dependency>
    <groupId>io.quarkiverse.amazonservices</groupId>
    <artifactId>quarkus-amazon-services-bom</artifactId>
    <version>4.0.0.Beta3</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

The command also generates a QuarkusSesSyncResourceTest class and a QuarkusSesSyncResourceIT class that call the hello endpoint of the generated resource. The next section replaces that resource: delete these two files, or update them to match the endpoints you create.

Creating the REST resource

First, let’s create the Email bean that represents the email to send:

package org.acme.ses.model;

import io.quarkus.runtime.annotations.RegisterForReflection;

@RegisterForReflection
public class Email {

    private String from;
    private String to;
    private String subject;
    private String body;

    public String getFrom() {
        return from;
    }

    public String getTo() {
        return to;
    }

    public String getSubject() {
        return subject;
    }

    public String getBody() {
        return body;
    }

    public Email setFrom(String from) {
        this.from = from;
        return this;
    }

    public Email setTo(String to) {
        this.to = to;
        return this;
    }

    public Email setSubject(String subject) {
        this.subject = subject;
        return this;
    }

    public Email setBody(String body) {
        this.body = body;
        return this;
    }
}
The @RegisterForReflection annotation instructs Quarkus to keep the class and its members during the native compilation. More details about the @RegisterForReflection annotation can be found on the native application tips page.

Then, create a org.acme.ses.QuarkusSesSyncResource that will provide an API to send emails using the synchronous client.

package org.acme.ses;

import jakarta.inject.Inject;
import jakarta.ws.rs.Consumes;
import jakarta.ws.rs.POST;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;
import org.acme.ses.model.Email;
import software.amazon.awssdk.services.ses.SesClient;

@Path("/sync")
@Produces(MediaType.TEXT_PLAIN)
@Consumes(MediaType.APPLICATION_JSON)
public class QuarkusSesSyncResource {

    @Inject
    SesClient ses;

    @POST
    @Path("/email")
    public String send(Email data) {
        return ses.sendEmail(req -> req
            .source(data.getFrom())
            .destination(d -> d.toAddresses(data.getTo()))
            .message(msg -> msg
                .subject(sub -> sub.data(data.getSubject()))
                .body(b -> b.text(txt -> txt.data(data.getBody()))))).messageId();
    }
}

Configuring Amazon SES clients

Both Amazon SES clients (sync and async) are configurable via the application.properties file that can be provided in the src/main/resources directory. Additionally, you need to add to the classpath a proper implementation of the sync client. By default, the extension uses the URL connection HTTP client, so you need to add a URL connection client dependency to the pom.xml file:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>url-connection-client</artifactId>
</dependency>

If you want to use the Apache 5.x HTTP client instead, configure it as follows:

quarkus.ses.sync-client.type=apache5

And add the following dependency to the application pom.xml:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>apache5-client</artifactId>
</dependency>

If you want to use the Apache HTTP client instead, configure it as follows:

quarkus.ses.sync-client.type=apache

And add the following dependency to the application pom.xml:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>apache-client</artifactId>
</dependency>

The AWS SDK has deprecated the Apache HTTP client in favor of the Apache 5.x HTTP client, which is a drop-in replacement: prefer apache5. The build logs a warning when the Apache HTTP client is used. Set quarkus.aws.sync-client.apache-deprecation-warning=false to disable it, see Deprecated Apache HTTP client.

If you want to use the AWS CRT-based HTTP client instead, configure it as follows:

quarkus.ses.sync-client.type=aws-crt

And add the following dependency to the application pom.xml:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>aws-crt-client</artifactId>
</dependency>

Use Dev Services

With Dev Services, there is nothing to configure: in dev and test modes, Dev Services starts Floci and configures the endpoint, the region and the credentials of the clients.

Use a manually started Floci

If you started Floci yourself, configure the client to use it as follows:

quarkus.ses.endpoint-override=http://localhost:4566 (1)

quarkus.ses.aws.region=us-east-1 (2)
quarkus.ses.aws.credentials.type=static (3)
quarkus.ses.aws.credentials.static-provider.access-key-id=test-key
quarkus.ses.aws.credentials.static-provider.secret-access-key=test-secret
1 Override the Amazon SES client to use Floci instead of the actual AWS service. When it is set, Dev Services does not start a local stack for Amazon SES.
2 Floci defaults to us-east-1
3 The static credentials provider lets you set the access-key-id and secret-access-key directly

Use your AWS account

If you want to work with an AWS account, you need an AWS account with access to Amazon SES and the AWS Command Line Interface, then remove or comment out the endpoint-override and the static credentials properties of the previous section. By default, the Amazon SES client extension uses the default credentials provider chain that looks for credentials in this order:

  • Java System Properties - aws.accessKeyId and aws.secretAccessKey

  • Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY

  • Credential profiles file at the default location (~/.aws/credentials) shared by all AWS SDKs and the AWS CLI

  • Credentials delivered through the Amazon ECS if the AWS_CONTAINER_CREDENTIALS_RELATIVE_URI environment variable is set and the security manager has permission to access the variable,

  • Instance profile credentials delivered through the Amazon EC2 metadata service

And the region from your AWS CLI profile will be used.

Without endpoint-override, Dev Services starts a local stack for Amazon SES in dev and test modes, and the client uses it instead of your AWS account. Removing the endpoint-override is therefore not enough to use your AWS account in these modes: also disable Dev Services for Amazon SES:

quarkus.ses.devservices.enabled=false

Dev Services never starts in production mode.

Verify the sender address

Floci rejects a send request when the sender address is not verified, but it does not require the recipient to be verified, and it does not send any email.

With Dev Services

You do not need the AWS CLI: list the sender addresses in application.properties:

quarkus.ses.devservices.verified-emails=from-quarkus@example.com

Dev Services verifies these addresses when it starts the Floci container, and also when it reuses a Floci container already started by another Quarkus application in dev mode.

On a manually started Floci

Verify the sender address with the AWS CLI of the Floci container:

docker exec floci aws ses verify-email-identity --email-address from-quarkus@example.com
On your AWS account

Amazon applies certain restrictions to new Amazon SES accounts, mainly to prevent fraud and abuse. All new accounts are in the Amazon SES sandbox. All the features of the Amazon SES are still available while in sandbox, but the following restrictions apply:

  • You can send mail to verified email addresses and domains or to the Amazon SES mailbox simulator

  • You can only send mail from verified email addresses and domains

  • You can send a maximum of 1 message per second.

Going production, you’d need to get your account out of the sandbox following the Amazon procedure.

We assume you are going to use the AWS SES sandbox for the sake of this guide. Before sending any email, you must verify the sender address, and, while in the sandbox, the recipient address, using the AWS CLI. You can use your personal email or any temporary email service available if you wish.

aws ses verify-email-identity --email-address <sender@email.address>
aws ses verify-email-identity --email-address <recipient@email.address>

Then open the mailboxes of those email addresses to follow the confirmation procedure. Once an email is approved, you can use it in your application.

Run the application in Dev Mode

Run the application in dev mode with:

./mvnw clean quarkus:dev

If you use Dev Services, it starts a Floci container and configures the Amazon SES clients to use it. The Dev Services card of the Dev UI, at http://localhost:8080/q/dev-ui, shows the container and the endpoint it exposes.

  • Send an email with the synchronous client:

curl -XPOST -H"Content-type: application/json" http://localhost:8080/sync/email \
    -d'{"from": "from-quarkus@example.com", "to": "to-quarkus@example.com", "subject": "Hello from Quarkus", "body": "Quarkus is awesome"}'

The response is the message id returned by SES. Remember that the sender address must be verified, even on Floci, and that a local instance does not actually send any email.

Next steps

Packaging

Packaging your application is as simple as ./mvnw clean package. It can then be run with java -jar target/quarkus-app/quarkus-run.jar.

With GraalVM or Mandrel installed, you can also create a native executable binary:

./mvnw clean package -Dnative

Without GraalVM or Mandrel, build the native executable inside a container:

./mvnw clean package -Dnative -Dquarkus.native.container-build=true

Depending on your system, that will take some time. Run the native executable with ./target/amazon-ses-quickstart-1.0.0-SNAPSHOT-runner.

Dev Services does not start in production mode, so you need to make sure that your application.properties file is configured to use your AWS account or a local stack. To use a local Floci instance, pass the endpoint and the credentials on the command line: 
java \
    -Dquarkus.ses.endpoint-override=http://localhost:4566 \
    -Dquarkus.ses.aws.region=us-east-1 \
    -Dquarkus.ses.aws.credentials.type=static \
    -Dquarkus.ses.aws.credentials.static-provider.access-key-id=test-key \
    -Dquarkus.ses.aws.credentials.static-provider.secret-access-key=test-secret \
    -jar target/quarkus-app/quarkus-run.jar

See the Packaging applications guide for more details.

Going asynchronous

Thanks to the AWS SDK v2.x used by the Quarkus extension, you can use the asynchronous programming model out of the box.

Create a org.acme.ses.QuarkusSesAsyncResource REST resource that will be similar to our QuarkusSesSyncResource but using an asynchronous programming model.

package org.acme.ses;

import io.smallrye.mutiny.Uni;
import jakarta.inject.Inject;
import jakarta.ws.rs.Consumes;
import jakarta.ws.rs.POST;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;
import org.acme.ses.model.Email;
import software.amazon.awssdk.services.ses.SesAsyncClient;
import software.amazon.awssdk.services.ses.model.SendEmailResponse;

@Path("/async")
@Produces(MediaType.TEXT_PLAIN)
@Consumes(MediaType.APPLICATION_JSON)
public class QuarkusSesAsyncResource {

    @Inject
    SesAsyncClient ses;

    @POST
    @Path("/email")
    public Uni<String> send(Email data) {
        return Uni.createFrom()
            .completionStage(
                ses.sendEmail(req -> req
                    .source(data.getFrom())
                    .destination(d -> d.toAddresses(data.getTo()))
                    .message(msg -> msg
                        .subject(sub -> sub.data(data.getSubject()))
                        .body(b -> b.text(txt -> txt.data(data.getBody()))))))
            .onItem().transform(SendEmailResponse::messageId);
    }
}

We create Uni instances from the CompletionStage objects returned by the asynchronous SES client, and then transform the emitted item.

To enable the asynchronous client, you also need to add the Netty HTTP client dependency to the pom.xml:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>netty-nio-client</artifactId>
</dependency>

If you want to use the AWS CRT-based HTTP client instead, configure it as follows:

quarkus.ses.async-client.type=aws-crt

And add the following dependency to the application pom.xml:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>aws-crt-client</artifactId>
</dependency>

Quarkus dev mode picks up the new resource, and restarts by itself when pom.xml changes: if the application is still running, wait a few seconds, then call it again. Otherwise, run it again with ./mvnw quarkus:dev.

  • Send an email with the asynchronous client:

curl -XPOST -H"Content-type: application/json" http://localhost:8080/async/email \
    -d'{"from": "from-quarkus@example.com", "to": "to-quarkus@example.com", "subject": "Hello from Quarkus", "body": "Quarkus is awesome"}'

Going further

You have built a Quarkus application that uses Amazon SES, developed locally against Dev Services and ready to run on your AWS account. You are all set to build great applications with Amazon SES, with the fast startup, the low memory footprint and the developer joy of Quarkus.

About the Duration format

To write duration values, use the standard java.time.Duration format. See the Duration#parse() Java API documentation for more information.

You can also use a simplified format, starting with a number:

  • If the value is only a number, it represents time in seconds.

  • If the value is a number followed by ms, it represents time in milliseconds.

In other cases, the simplified format is translated to the java.time.Duration format for parsing:

  • If the value is a number followed by h, m, or s, it is prefixed with PT.

  • If the value is a number followed by d, it is prefixed with P.
About the MemorySize format

A size configuration option recognizes strings in this format (shown as a regular expression): [0-9]+[KkMmGgTtPpEeZzYy]?.

If no suffix is given, assume bytes.
