Your application's emails, from your own domain.

Connect mailronix to your software to send confirmations, receipts and notifications. Use templates with variables and check the status of every message.

Start for free Read the API documentation

Up to 500 unique recipients per day. Sign up with a work email and verify your domain to send. No credit card.

One integration for your sends.

Create a brand-linked key from the console and enable the permissions you need. Send HTML and text content, or call a template with its variables.

Reduce duplicates on repeated requests.

The Idempotency-Key header lets you repeat an identical request within 24 hours without starting a new send. A key reused with different content is rejected.

Get the updates.

Check the status of an email through the API, or receive delivery, bounce, complaint, failure and suppression events via webhook.

Opens are not among the events. The email.clicked event exists only for brands that have turned on click tracking, and only for recipients who have consented.

Add attachments when you need them.

Transactional emails support up to five attachments, 7 MB in total. Attachments are not available in marketing emails.

Set up in the console, send from your application.

Brands, domains, templates, keys and webhooks are configured in the console. API keys allow the intended operations on emails and contacts, not full account management.

Start on the Free plan.

3,000 emails per month, shared with the account's other sends, and up to 500 unique recipients per day.

Illustrative example

Example: an order confirmation

Illustrative example: addresses, template and values are invented. The key is read from the environment, never written in code.

curl -X POST https://api.mailronix.com/email/send \
  -H "Authorization: Bearer $MAILRONIX_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: ordine-4821" \
  -d '{
    "from": "[email protected]",
    "to": "[email protected]",
    "template_id": "<template-id>",
    "variables": { "numero_ordine": "4821" }
  }'

Questions about transactional email

Can I send attachments?

Yes, but only in transactional email: up to five attachments, 7 MB in total. Marketing emails do not support attachments.

What happens if I repeat a request by mistake?

With the Idempotency-Key header, an identical request repeated within 24 hours does not start a new send. If you reuse the same key with different content, the request is rejected.

How do I receive send outcomes?

You can check the status of an email through the API or receive events via webhook. Webhook endpoints are configured from the console, not with an API key. Opens are not among the events.
