Elastic Email Angular SDK

The official Angular client library for the Elastic Email REST API v4, built on Angular's HttpClient and RxJS.

Features

• Transactional and bulk email. Send single messages, bulk campaigns or CSV merge-file sends.
• Contacts, lists and segments. Add, update, import, export and bulk-delete contacts.
• Campaigns and automations. Create, update, pause and trigger automations for a contact.
• Templates, files and attachments. Manage templates and uploaded files.
• Domains. Verify sending domains and check SPF, DKIM, tracking and certificate status.
• Webhooks and inbound routes. Receive delivery events and route incoming mail.
• Statistics, events and suppressions. Track delivery, bounces, complaints and unsubscribes.
• Subaccounts and security. Manage subaccounts and API keys.
• Angular-native. Every API class is an injectable service (providedIn: 'root') built on HttpClient. Methods return RxJS Observables, and every request and response has a TypeScript type.

Requirements

Platform	Version
Angular	19 (@angular/core and @angular/common ^19.0.0)
RxJS	^7.4.0
TypeScript	>=5.5.0 <5.7.0

You'll also need an Elastic Email API key. You can create one in your API settings. Each endpoint's documentation lists the access level it needs.

Installation

Install the @elasticemail/elasticemail-client-ts-angular package from npm:

npm install @elasticemail/elasticemail-client-ts-angular

Or with yarn or pnpm:

yarn add @elasticemail/elasticemail-client-ts-angular
pnpm add @elasticemail/elasticemail-client-ts-angular

Angular and RxJS are peer dependencies, so the SDK uses the versions your app already has. The package is built with ng-packagr in the Angular Package Format, so there's nothing to compile.

Quick start

Important

Elastic Email only sends from verified domains. Before your first send, verify your sending domain and use an address on that domain as the sender.

Important

Never ship your API key to a browser. Anything in your Angular bundle can be read by anyone who loads the page. Use the SDK with a key only in server-side code (for example Angular SSR), or point the browser build at your own backend, which adds the key. See Call through your own backend.

Configure the client

Provide HttpClient and a Configuration with your API key. With Angular SSR, put the key in the server config (app.config.server.ts) so it never reaches the browser bundle:

// app.config.server.ts
import { mergeApplicationConfig, ApplicationConfig } from '@angular/core';
import { provideServerRendering } from '@angular/platform-server';
import { Configuration } from '@elasticemail/elasticemail-client-ts-angular';
import { appConfig } from './app.config';

const serverConfig: ApplicationConfig = {
  providers: [
    provideServerRendering(),
    {
      provide: Configuration,
      useFactory: () => new Configuration({
        credentials: { apikey: () => process.env['ELASTICEMAIL_API_KEY'] },
      }),
    },
  ],
};

export const config = mergeApplicationConfig(appConfig, serverConfig);

// app.config.ts
import { ApplicationConfig } from '@angular/core';
import { provideHttpClient, withFetch } from '@angular/common/http';

export const appConfig: ApplicationConfig = {
  providers: [provideHttpClient(withFetch())],
};

The API services (EmailsService, ContactsService…) are providedIn: 'root', so you inject them directly. You don't need to import ApiModule.

Tip

Keep your API key out of source code. Load it from an environment variable, a .env file that isn't committed, or a secrets manager.

Send a transactional email

import { Injectable, inject } from '@angular/core';
import { HttpErrorResponse } from '@angular/common/http';
import { firstValueFrom } from 'rxjs';
import {
  BodyContentType,
  EmailsService,
  EmailTransactionalMessageData,
} from '@elasticemail/elasticemail-client-ts-angular';

@Injectable({ providedIn: 'root' })
export class WelcomeMailer {
  private readonly emails = inject(EmailsService);

  async sendWelcome(to: string): Promise<void> {
    const message: EmailTransactionalMessageData = {
      Recipients: {
        To: [to],
      },
      Content: {
        From: 'My App <no-reply@yourdomain.com>',
        Subject: 'Welcome aboard!',
        Body: [
          { ContentType: BodyContentType.Html, Content: '<h1>Hello!</h1><p>Thanks for signing up.</p>' },
          { ContentType: BodyContentType.PlainText, Content: 'Hello! Thanks for signing up.' },
        ],
      },
    };

    try {
      const result = await firstValueFrom(this.emails.emailsTransactionalPost(message));
      console.log(`Sent. TransactionID: ${result.TransactionID}, MessageID: ${result.MessageID}`);
    } catch (error) {
      if (error instanceof HttpErrorResponse) {
        console.error(`Elastic Email API error ${error.status}:`, error.error);
      } else {
        throw error;
      }
    }
  }
}

The From address must use a domain you've verified in your Elastic Email account.

Note

Each method returns a cold Observable: nothing is sent until you subscribe (or call firstValueFrom). By default it emits the response body. Pass 'response' as the observe argument to get the full HttpResponse, or 'events' for progress events. Field names match the API's PascalCase names (Recipients, Content, TransactionID…).

Send from a template with merge fields

this.emails.emailsTransactionalPost({
  Recipients: { To: ['john.doe@example.com'] },
  Content: {
    From: 'My App <no-reply@yourdomain.com>',
    TemplateName: 'welcome-template',
    Merge: { firstname: 'John' },
  },
}).subscribe(result => console.log(result.TransactionID));

Call through your own backend

In a browser build, leave the key out and set basePath to an endpoint on your own server that adds the X-ElasticEmail-ApiKey header and forwards the request to https://api.elasticemail.com/v4:

// app.config.ts (browser)
import { Configuration } from '@elasticemail/elasticemail-client-ts-angular';

providers: [
  provideHttpClient(withFetch()),
  { provide: Configuration, useValue: new Configuration({ basePath: '/api/elasticemail' }) },
],

You can also provide the base path on its own with the BASE_PATH injection token: { provide: BASE_PATH, useValue: '/api/elasticemail' }.

Timeouts and headers

Requests go through Angular's HttpClient, so use an interceptor for headers, timeouts or retries on every call:

import { HttpInterceptorFn, provideHttpClient, withFetch, withInterceptors } from '@angular/common/http';
import { timeout } from 'rxjs';

const elasticEmailInterceptor: HttpInterceptorFn = (req, next) =>
  next(req.clone({ setHeaders: { 'X-My-Header': 'x' } })).pipe(timeout(30000)); // ms

providers: [provideHttpClient(withFetch(), withInterceptors([elasticEmailInterceptor]))],

For a single call, pipe RxJS operators onto the returned Observable, e.g. this.emails.emailsTransactionalPost(message).pipe(timeout(30000)).

Using ApiModule in an NgModule app

import { NgModule } from '@angular/core';
import { provideHttpClient } from '@angular/common/http';
import { ApiModule, Configuration } from '@elasticemail/elasticemail-client-ts-angular';

export function apiConfigFactory(): Configuration {
  return new Configuration({ basePath: '/api/elasticemail' });
}

@NgModule({
  imports: [ApiModule.forRoot(apiConfigFactory)],
  providers: [provideHttpClient()],
  declarations: [AppComponent],
  bootstrap: [AppComponent],
})
export class AppModule {}

Import ApiModule once, in your root module only. Importing it a second time throws ApiModule is already loaded.

Customizing path parameter encoding

By default only path parameters of style simple, and dates in date-time format, are encoded. Every Elastic Email path parameter uses the simple style, so most apps don't need to change this. To use your own encoder, pass encodeParam to the Configuration:

import { Configuration, Param } from '@elasticemail/elasticemail-client-ts-angular';

new Configuration({
  encodeParam: (param: Param) => myParamEncoder(param),
});
