Introduction

Piisend is the email API for developers—transactional and marketing mail over HTTPS with webhooks, domains, and a dashboard.

Piisend helps you send transactional email (OTPs, receipts, password resets) and promotional campaigns from your app using a REST API. No proprietary runtime required—use curl, JavaScript fetch, or Python httpx.

What you get

  • REST API at https://api.piisend.com
  • Dashboard for API keys, domains, templates, logs, and suppressions
  • Webhooks for delivery, bounce, complaint, open, and click events
  • Verified domains for branded from_ addresses

Recommended path

  1. Read the Quickstart and send your first email.
  2. Browse the Sending guides for attachments, scheduling, idempotency, and more.
  3. Set up Domains and Webhooks before production traffic.
