How do I create a sender / from address?

There is no separate "sender" object to create in MailBlastr. Unlike platforms that make you register and verify each individual from address, MailBlastr verifies at the domain level. Once a domain is verified, any address on it can be used as the from of an email or campaign — no extra setup per address.

How it works

1. 1
   Verify your domain once

   Add your domain under Domains and publish its SPF/DKIM/DMARC records. See Managing domains.

2. 2
   Pick any address on it

   After the domain is verified, hello@, receipts@, news@, support@, or any other mailbox on that domain is a valid from. You do not create them anywhere first.

3. 3
   Send

   Put the address in the from field. MailBlastr checks the domain part is one of your verified domains and sends.

The from format

The from field accepts either a bare address or a friendly display name with the address in angle brackets:

Acme <hello@yourdomain.com>   ← display name + address (recommended)
hello@yourdomain.com          ← bare address

MailBlastr extracts the address from inside the <…> and checks that its domain (yourdomain.com) is verified for your account. A subdomain of a verified domain also works.

import { MailBlastr } from 'mailblastr';

const mb = new MailBlastr('mb_xxxxxxxxx');

const { data, error } = await mb.emails.send({
  "from": "Acme Support <support@yourdomain.com>",
  "to": ["customer@example.com"],
  "subject": "We got your message",
  "html": "<p>Our team will reply shortly.</p>"
});
console.log({ data, error });
