Destinatarium is a service for sending transactional email from applications through a simple API. It is built for OTPs, receipts, password resets and other notifications your users expect to receive.

It is email an application sends automatically after an action or event, such as creating an account, requesting a new password, completing a purchase or receiving a notification. It is part of the product experience rather than a marketing campaign.

Create an account, add and verify the domain you will use as the sender, generate an API key with sending permission and make your first request. The API documentation includes a complete cURL example.

Yes. The domain in your sender address must be verified and active in your account. This proves you are authorized to use it and helps receiving servers authenticate your messages.

To integrate sending into an application, you need to be able to make an HTTP request to the API. Our documentation provides an example ready to adapt; if you work with a technical team, they can usually connect it in a few steps.

You can send account confirmations, login codes or OTPs, password resets, receipts, order updates and other notifications related to your users’ actions.

No. Destinatarium focuses on transactional email rather than bulk marketing campaigns. This specialization lets us keep our infrastructure centered on the operational messages your users need to receive.

Destinatarium processes each accepted request asynchronously and gets it on its way as quickly as possible. Final delivery time also depends on the receiving server, sender reputation and its security filters.

The dashboard shows your sending history and the available status for each message. This lets you follow its journey and investigate an issue without working in the dark.

No provider can guarantee inbox placement 100% of the time. The final destination depends on sender authentication and reputation, message content and recipient filters. Destinatarium processes the send correctly and gives you visibility into its status.
