Frequently asked questions
What should you know before sending?
Straight answers to the questions teams usually ask before integrating a transactional email API.
View all questionsWhat is Destinatarium and what is it used for?
Destinatarium is a transactional email service for applications. It lets you send OTP codes, account confirmations, password resets, receipts and notifications automatically through a REST API. It is designed for teams that want a quick integration, visibility into each message status, and a single dashboard for keeping domains, senders and projects organized.
How do I start sending transactional email with Destinatarium?
First create an account, add the domain you will use as the sender and verify it with the requested DNS records. Then generate an API key with sending permission and make an HTTPS request using the example in the documentation. You can start on the free plan and test the integration without entering a credit card.
Can I send newsletters or marketing campaigns with Destinatarium?
No. Destinatarium specializes in transactional email: messages triggered by a specific action or event inside your product. That includes login codes, receipts, alerts and account updates. For newsletters, promotions or bulk campaigns, you need an email marketing platform built to manage subscriber lists, consent, audience segmentation and unsubscribe requests.
Do I need to verify my domain before sending email?
Yes. You must verify the domain in your sender address before using it in production. The platform shows which DNS records to add so you can prove authorization and authenticate your email. Correct SPF, DKIM and DMARC configuration helps protect your domain from spoofing and gives receiving mail servers stronger reasons to trust your messages.
How much does Destinatarium cost, and is there a free plan?
Yes. The Free plan includes up to 4,000 emails per month and does not require a credit card. Paid plans start at $5.99 per month and increase email volume, domains, senders, data retention and support. Some plans also allow additional usage; compare the latest limits and terms in the pricing section before choosing one.
Does Destinatarium guarantee that my email reaches the inbox?
No provider can guarantee inbox placement in every case because the final decision depends on the receiving server, domain reputation, authentication and message content. Destinatarium processes the send and exposes its status so you can track it. Using legitimate recipients, configuring your domain correctly and sending expected content improves the likelihood of successful delivery.
