Resend MCP integration
Sends the confirmation a conversation just promised, reschedules or cancels queued mail, segments contacts, and checks whether a message landed.
62actions available
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.
Send EmailSend Batch EmailsGet TemplateChange 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.
Update EmailCancel EmailRetrieve EmailPut 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.

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.
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.
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.
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.

FAQ
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.
