Brahmastra Mailer
What this bulk email software actually does
Most “email marketing platforms” host your list in the cloud. Brahmastra is desktop bulk email sending software: each operator opens an isolated Chrome profile, signs into Gmail, Xero, or a document site, and runs a licensed panel. That is the product — high-volume sending from accounts you control.
- Bulk email sender (Gmail): recipient lists, subject, body, attachments, pause and resume.
- Email sending API: G-Api uses Gmail API OAuth for campaigns, contacts, Drive, and calendar.
- Invoice email campaigns: 1 To + 19 BCC per Xero organisation (20 emails), then the next org.
- Document bulk send: WeTransfer, SignNow, SignEasy, and related sites from One Sender.
Bulk email software vs a hosted bulk email service
A bulk email service such as Mailchimp or Brevo stores audiences, templates, and analytics on their servers. Brahmastra is bulk email software you install. Choose a cloud ESP if you need hosted templates, journey builders, and their IP reputation. Choose Brahmastra if your workflow is Gmail, Xero, or file platforms on Windows PCs.
Who this email campaign software is for
Agencies, marketers, ecommerce operators, and startups that already send from Gmail or need Xero invoice volume. It is licensed software — not free bulk email software and not a harvested-list spam tool. See Terms.
