OfficialNot API testedRequest tested

ZeptoMail supports recipient objects, CC, BCC, reply-to, and attachments. It intentionally rejects headers, metadata, and tags because the adapter does not map them to the ZeptoMail API.

Before live sends

Create a ZeptoMail API token and verify the sending domain in Zoho ZeptoMail. The adapter accepts tokens with or without the Zoho-enczapikey prefix.

Configure

import { createEmailClient } from "@opencoredev/email-sdk";
import { zeptomail } from "@opencoredev/email-sdk/zeptomail";

const email = createEmailClient({
  adapters: [zeptomail({ token: process.env.ZEPTOMAIL_TOKEN! })],
});

Send

const result = await email.send({
  from: { email: "hello@acme.com", name: "Acme" },
  to: [{ email: "user@example.com", name: "Ada" }],
  cc: "billing@example.com",
  replyTo: "support@example.com",
  subject: "ZeptoMail test",
  html: "<p>It works.</p>",
  attachments: [
    {
      filename: "receipt.txt",
      content: "Thanks for your order.",
      contentType: "text/plain",
    },
  ],
});

console.log(result.provider, result.id);

ZeptoMail supports recipients, reply-to, and attachments. It rejects headers, metadata, and tags before the API call.

Send text only

await email.send({
  from: "Acme <hello@acme.com>",
  to: "user@example.com",
  subject: "Plain update",
  text: "Your account has been updated.",
});

Options

`baseUrl`	`string`	No	Defaults to `https://api.zeptomail.com`.
`fetch`	`typeof fetch`	No	Useful for tests or custom runtimes.

ZeptoMail supports recipients, reply-to, and attachments. Unsupported fields throw before the API call.

Response
