Maail is the email intelligence and delivery layer between the outside world and your product.
As a service of a German company, Maail is governed by European law. Address analysis and spam classification are stateless: we return the result and discard the submitted payload. For sending, inbound email and mailbox migration, only the operational data required to complete the requested task is retained.
Email addresses and message content submitted for analysis are not retained after the result is returned.
Privacy is a core operating principle shaped by European data-protection standards.
Inbound, sending and migration data is handled only for the workflow you explicitly request.
Transient intelligence endpoints stay separate from services that require operational state.
Each capability solves a concrete job. Together they cover the path from the first address entered into a form to the last message your application receives, sends or moves between providers.
Maail looks beyond syntax. It identifies what kind of mailbox you are dealing with and returns a clear recommendation for your signup, lead or account workflow.

Give a workflow its own inbound address. Maail receives the message, normalizes email complexity and delivers a structured event to your application.
invoice-route@inbound.example
email.received → your webhook
Send transactional messages directly or render a reusable template with variables. Your application provides the data; Maail builds and accepts the message.

Send raw RFC 822 or structured message content. Maail uses an LLM to understand the intent and returns a decision your mail gateway or product can act on.

Connect a source and destination mailbox, then let Maail copy the complete history while preserving the structure users expect. Run a final catch-up pass before switching MX records so nothing is missed.

Maail hides transport and parsing details behind predictable resources, events and decisions.
Call the API, send a message or let Maail receive email for a configured route.
Provider data, message structure and model reasoning become a clean response.
Accept the user, reject spam, trigger a workflow or continue with a message ID.
Every request uses Bearer authentication, JSON by default and a stable request ID. Raw email can also be
sent as message/rfc822.

}Maail is a service of a German company and falls under European law. Address analysis and spam classification are stateless and their submitted payloads are not stored. Inbound, outbound and migration data exists only for the configured workflow and only as long as operationally required.
Every plan includes address intelligence, inbound routes, transactional sending, spam classification, and API access. Upgrade when volume grows.
For prototypes and small production workflows.
For products with recurring email workflows.
For higher-volume and business-critical systems.
Additional usage is billed monthly. Mailbox migrations are priced separately by mailbox size and volume.
Validation is one signal, but the product goes further. Maail classifies the mailbox and its context—such as business, education, personal, role-based or disposable—and returns a recommendation your product can use directly.
You create an inbound route and receive an address such as invoice-route@inbound.example. Every message to that route is normalized and delivered as a signed email.received event to your webhook.
Yes. The messages endpoint accepts direct subject, HTML and text content, or a stored template plus variables. Templates are useful for repeated transactional messages but are not mandatory.
It can be used independently, but the strongest mail pipeline combines authentication, reputation, deterministic rules and semantic classification. Maail is the content-aware decision signal in that stack.
Yes. Call the spam endpoint as an additional policy signal and define explicit timeout and fail-open behavior. For deeper analysis without SMTP latency, classify after accepting the message into the queue.
Maail copies messages through IMAP while preserving folder structure, read and flagged states, and internal message dates. Migration jobs are resumable, expose progress and can perform an incremental catch-up pass immediately before the final provider switch.
Analysis and classification are transient by default. Inbound routing and sending retain only what is explicitly required by the configured workflow and delivery process.
