## EmailGenerator

<GenerationInfo sourceFile="packages/email-plugin/src/generator/email-generator.ts" sourceLine="15" packageName="@vendure/email-plugin" />

An EmailGenerator generates the subject and body details of an email.

```ts title="Signature"
interface EmailGenerator<T extends string = any, E extends VendureEvent = any> extends InjectableStrategy {
    onInit?(options: EmailPluginOptions): void | Promise<void>;
    generate(
        from: string,
        subject: string,
        body: string,
        templateVars: { [key: string]: any },
    ): EmailGeneratorResult | Promise<EmailGeneratorResult>;
}
```

* Extends: [`InjectableStrategy`](/current/core/reference/typescript-api/common/injectable-strategy#injectablestrategy)

<div className="members-wrapper">

### onInit

\<MemberInfo kind="method" type={`(options: <a href='/current/core/reference/core-plugins/email-plugin/email-plugin-options#emailpluginoptions'>EmailPluginOptions</a>) => void | Promise<void>`}   />

Any necessary setup can be performed here.

### generate

\<MemberInfo kind="method" type={`(from: string, subject: string, body: string, templateVars: { [key: string]: any }) => EmailGeneratorResult | Promise<EmailGeneratorResult>`}   />

Given a subject and body from an email template, this method generates the final
interpolated email text.

## HandlebarsMjmlGenerator

<GenerationInfo sourceFile="packages/email-plugin/src/generator/handlebars-mjml-generator.ts" sourceLine="17" packageName="@vendure/email-plugin" />

Uses Handlebars (https://handlebarsjs.com/) to output MJML (https://mjml.io) which is then
compiled down to responsive email HTML.

```ts title="Signature"
class HandlebarsMjmlGenerator implements EmailGenerator {
    onInit(options: InitializedEmailPluginOptions) => ;
    generate(from: string, subject: string, template: string, templateVars: any) => ;
}
```

* Implements: [`EmailGenerator`](/current/core/reference/core-plugins/email-plugin/email-generator#emailgenerator)

<div className="members-wrapper">

### onInit

\<MemberInfo kind="method" type={`(options: InitializedEmailPluginOptions) => `}   />

### generate

\<MemberInfo kind="method" type={`(from: string, subject: string, template: string, templateVars: any) => `}   />
