RAPID SMTP is a bring-your-own-SMTP email platform from RapidHost BD. Send through your own Gmail, SES or Mailgun — we handle the dashboard, contacts, scheduling, deliverability and analytics. You keep the reputation.

The RAPID SMTP envelope-in-motion stands for what we ship every day — email that leaves your SMTP and reaches the inbox without friction. The deep blue is borrowed from our parent company, RapidHost BD, signalling reliability, infrastructure, and the same engineering standard behind tens of thousands of customer workloads.
The big email platforms force you onto their sending infrastructure, charge per recipient forever, and treat your contact list like their asset. If you ever leave, you start from zero — new IP, new reputation, new domain warm-up.
We built RAPID SMTP to flip that. Plug in the SMTP you already own — Gmail, Amazon SES, Mailgun, Postmark, SendGrid or a self-hosted relay — and we provide everything around it: contact management, scheduled campaigns, templates with merge tags, open/click tracking, unsubscribe handling, and a background worker that keeps sending after you close the browser.
The result: flat BDT pricing, no per-email charges, full deliverability control, and a clean exit path if you ever outgrow us.
Your SMTP, your contacts, your sender reputation. We're the cockpit, not the airline.
AES-256-GCM encrypted credentials, RLS-backed isolation, audit logs on every privileged action.
BDT pricing, bKash/Nagad/Rocket support, Bengali documentation, and South-Asia-fast edge infrastructure.
