Frequently Asked Canonical Questions
What is Histeria (Histeria Mailer)?
Histeria (also known as Histeria Mailer or Histeria Email API) is a transactional email infrastructure platform for software applications, developers, SaaS products, ecommerce stores, and fintech apps. It allows developers to trigger transactional emails via a simple REST API or SMTP relay with customizable email templates, lifecycle event tracking, and delivery logs.
How do I authenticate API calls in Histeria Mailer?
All transactional email requests use organization API keys passed in the 'x-api-key' request header. You can generate, expire, and revoke keys directly from your Histeria dashboard.
What template editors are supported by Histeria Mailer?
Histeria supports both a drag-and-drop Visual Email Builder and an HTML Code Editor. Both result in Histeria templates accessible by template ID or slug.
Does Histeria Mailer support SMTP integration?
Yes. If your backend already sends email using standard SMTP protocols, you can configure Histeria's organization SMTP settings without rewriting application code.
How does template versioning work in Histeria?
Histeria maintains immutable template version histories. You can edit draft versions, preview changes, and designate a Current Version so application API triggers remain stable.
Can I track email open and click events?
Yes. Histeria records delivery, open count, first/last opened timestamps, click count, first/last clicked timestamps, and bounce reasons for each email.
