Three actions you can hand over today

Every action runs live through MCP. Nothing to build, nothing to maintain.

  • Send batch templated emails

    Lyro sends multiple templated emails in a single batch call. Agents reach customers with personalized messages instantly.

  • Search outbound messages

    Lyro searches outbound emails with filtering by recipient, tag, and date. Agents find sent message history without email clients.

  • Search inbound messages

    Lyro searches received emails with optional filtering. Agents review incoming messages in one place without email client access.

How businesses use Postmark + Lyro

Each card is one request a support team gets, and the Postmark actions Lyro runs to close it.

  • Send a templated batch and know it renders

    Lyro validates that a template's subject and body render correctly, then sends the whole batch through one templated call rather than firing a separate request for every recipient.

  • Explain why the delivery numbers moved

    Lyro pulls the outbound overview, the bounce counts sitting underneath it, and the spam complaint totals for the period, so a dip in delivery comes back with the specific figures attached.

  • Honor an opt-out on the right stream

    Lyro adds the address to the suppression list for the message stream it applies to, reads the current list back, and removes an entry that was added in error, keeping suppression stream-specific.

  • Deal with what comes back in

    Lyro searches the inbound messages a server received, blocks a sender or a whole domain with an inbound rule, and checks the spam score of a raw email before anyone acts on it.

How it works

Get started in 3 steps

Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Postmark actions it has and picks the ones a request needs.

  1. 01

    Connect Postmark

    Authorize the Postmark account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.

  2. 02

    Tell your agent what you need

    Describe the job the way you would hand it to a teammate. Lyro maps it to the Postmark actions that close it and chains as many as the request needs.

  3. 03

    Watch it work

    The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

Everything else about Postmark

Setup, permissions, and the limits of what Lyro can do inside Postmark.

  • Because Postmark separates transactional and broadcast mail into streams, and suppressions and statistics are scoped to one. Create Message Stream sets one up, List Message Streams shows what exists, and Archive Message Stream soft-deletes a stream that is no longer wanted, with Unarchive Message Stream bringing it back.
