Three actions you can hand over today

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

  • Send email

    Lyro sends an email using Resend's email delivery service. Support teams can notify customers immediately with transactional messages or marketing communications.

  • Create contact

    Lyro creates a new contact in Resend for email campaigns and communications. Support teams can add customers to the platform without manual admin access, keeping records synchronized.

  • Update contact

    Lyro updates an existing contact in Resend by their ID or email address. Agents can keep customer information current, ensuring future emails reach the right person with correct details.

How businesses use Resend + Lyro

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

  • Send the email the conversation just promised

    Lyro sends the receipt or follow-up an exchange ends on, pulls a stored template so the wording matches everything else you send, and batches up to 100 messages in one call when it is a list.

  • Change your mind before it sends

    Lyro updates a scheduled email when the details change and cancels it outright when the customer resolves the issue another way, so a promised follow-up does not arrive after it stopped being true.

  • Put the contact in the right segment

    Lyro creates the contact if they are new, adds them to the segment their request implies, and checks which topics they are already subscribed to before anything else is queued for them.

  • Get a sending domain live

    Lyro creates the domain in its pending state, runs verification once the DNS records have propagated, and reports which domains on the account are actually cleared to send from.

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 Resend actions it has and picks the ones a request needs.

  1. 01

    Connect Resend

    Authorize the Resend 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 Resend 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 Resend

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

  • The Send Email action is defined to confirm recipients and content before it is invoked, so a send is the closing step of an exchange rather than a silent side effect. If something does go out early, Cancel Email pulls a scheduled message and Update Email rewrites it.
