All FAQsCan I run email marketing from inside my SaaS product?
Yes. On an Enterprise account, the tinyEmail REST API lets your product add and update contacts, manage audiences, create, schedule and start campaigns, and pull campaign reports, all from your own code.
Which tinyEmail plan includes the API?
The REST API is available on Enterprise accounts. Each API key can make 60 requests a minute, and support can raise the limit if you need more.
Should password resets and receipts go through tinyEmail campaigns?
No. Send them through tinyRelay, our SMTP relay and transactional email service. It sends one-to-one emails over SMTP or a REST API on the same delivery infrastructure, with signed webhooks for every event.
Can I show email results inside my own product?
Yes. The API returns each campaign's sends, deliveries, opens, clicks, spam reports and unsubscribes by recipient domain, so you can show them in your own dashboards.
Is there an SDK for the tinyEmail API?
No SDK is needed. It's a REST API, so you call it from any language that can make HTTP requests, including Node.js, Python, PHP, Ruby and Go.
What if the API is missing something we need?
Tell us. If you can do something in the tinyEmail dashboard that isn't in the API yet, the team will work to expose it.
