How businesses use Mailersend + Lyro

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

  • Explain what happened to a message that was sent

    Lyro pulls the message log for the account, filters recipients by list or search term, and checks the SMS side of the same account, so a missing-email question is answered from the delivery record.

    Get Sent MessagesGet Email RecipientsList SMS Messages
  • Check whether a sending domain is actually verified

    Lyro reads the DKIM, SPF, MX, and tracking status for a domain along with its paused flag, which is usually the real answer when mail from a newly added domain is not arriving.

  • Provision a new sending domain end to end

    Lyro registers the domain, creates the SMTP user that will authenticate against it, and issues a scoped API token for the application that sends through it.

  • Wire delivery events to the system that needs them

    Lyro creates a webhook on a domain for the events you care about - sent, delivered, opened - lists what is already configured, and deletes an endpoint that has been retired.

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

  1. 01

    Connect Mailersend

    Authorize the Mailersend 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 Mailersend 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 Mailersend

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

  • No. This toolkit covers account and infrastructure operations - domains, SMTP users, API tokens, webhooks - plus read access to the message, recipient, and SMS logs. There is no send action in it, so Lyro investigates and configures the sending setup rather than dispatching mail through it.
