# Sending email in Javascript and NodeJS (Typescript examples)

Sending email with MailSlurp is easy. Simply create an inbox and use the inbox's ID with sendEmail() methods.

# Basics

The basic sendEmail() method has the following signature:

sendEmail(inboxId: string, sendEmailOptions: SendEmailOptions): Promise<Response>

Notice the inboxId. This is the inbox from which the emails will be sent. The second parameter contains properties describing the email to be sent.

# Options

The only required property of SendEmailOptions is a to field — which is an array of email addresses.

  "to": ["user@mycompany.com"]

Other optional fields include the following:

interface SendEmaiOptions {
  to: Array<string>;
  // email subject
  subject?: string;
  // extra recipient fields
  cc?: Array<string>;
  bcc?: Array<string>;
  // email contents
  body?: string;
  // array of attachment IDs
  attachments?: Array<string>;
  // map of template variables to substitute in body
  templateVariables?: any;
  // optional headers
  charset?: string;
  replyTo?: string;
  from?: string;
  // is contents HTML?
  html?: boolean;

# Example

await mailslurp.sendEmail(inboxId, { to: ["user@test.com"], body: "Hello" });

# HTML and templates

You can flag { "html": true } when sending emails to indicate that HTML content is being sent. This is recommend if you want email providers to render markup correctly.

You can also pass a map of templateVariables when sending an email and MailSlurp will look for and interpret Moustache templates within your email body.

  "body": "Hello {{name}}",
  "templateVariables": {
    "name": "tester"
