Frequently asked questions
Quick answers about setup, sending behavior, and integration.
What is Piisend used for?
Piisend is an email API for transactional mail (OTP, verification, password reset) and marketing or promotional campaigns. You integrate via HTTPS with curl, JavaScript, or Python examples in the docs.
Can I send from my own domain?
Yes. Verify your domain with DNS (SPF, DKIM) and set from_ on API sends. Until verification completes, a shared platform address can be used.
How do I integrate with my app?
Create an API key from the dashboard (API → Keys), then call POST /api/v1/emails. See /docs/getting-started and /docs/api for curl, JavaScript (fetch), and Python (httpx) examples.
Do you support event visibility?
Yes. Delivery-related events appear via webhooks and in message detail. Subscribe to delivery, bounce, complaint, open, and click events.
