About Mailjar

Mailjar turns inbound email into something a program can read. Point a domain at it, and every message that arrives is captured, parsed, and mined for the bits that matter — the verification code, the magic link, the order number — then handed back over a clean API, an MCP server, or a simple web inbox.

Why it exists

The same problem shows up everywhere: a flow sends an email, and you need what's inside it from code. An end-to-end test signs a user up and waits on a six-digit code. An AI agent needs to confirm an account. An automation wants the receipt total. Historically you'd wire up a throwaway mailbox and scrape it over IMAP, or pay a service that charges per parse and locks each feature behind a higher tier.

Mailjar takes the boring path and makes it a one-liner. You own the addresses, the mail is parsed the moment it lands, and the code is one authenticated request away.

What we believe

• Receive-only, on purpose. Mailjar captures, parses and exposes inbound mail. It never sends — so it can't be turned into a spam cannon, and the security story stays simple.
• Features aren't a tier. Every capability is available to every account. When we charge, we'll charge for volume, never for unlocking a feature. More on pricing →
• Private by default. Addresses are owned and exclusive. No public, guessable inboxes — those leak OTPs, which is the opposite of the point.
• Open standards. A real REST API with OpenAPI, an llms.txt, and a native MCP server — with read-only IMAP and JMAP on the roadmap. No proprietary-only lock-in.
• EU-hosted. Mail is processed and stored in the EU (Google Cloud, europe-west4), which keeps the GDPR story clean for European teams.

Part of a pair

Mailjar has a sibling: Hookjar, which does the same job for inbound HTTP — catch a webhook, inspect it, replay it. Mailjar is the email half. Same conventions, same login, same idea: capture whatever is sent to you and make it easy to work with.

Where it's going

• Deliverability reports (SPF/DKIM/DMARC + spam scoring) on every message
• Attachment OCR and user-defined entity extraction (order #, totals, tracking)
• Read-only IMAP and JMAP, so any mail client or test tool works with zero integration
• A self-hosted edition for teams that can't route mail to a third party
