Mails so MCP integration
Validates a single address on the spot, submits lists for bulk checking, and pulls batch results once the job has finished.
3actions available
Three actions you can hand over today
Every action runs live through MCP. Nothing to build, nothing to maintain.
Validate single email
Lyro checks whether a single email address is valid and deliverable. Your agent can verify subscriber email quality before adding them to a campaign.
Validate bulk emails
Lyro validates hundreds of email addresses at once to identify bad addresses in a list. Support can now clean email lists in bulk without manual checking.
Retrieve batch results
Lyro fetches the results of a completed bulk email validation job. Your team can review validation findings without polling or waiting for an email notification.
How businesses use Mails so + Lyro
Each card is one request a support team gets, and the Mails so actions Lyro runs to close it.
Verify an address before it enters your CRM
When someone gives an email in chat, Lyro checks its deliverability and quality first, so a mistyped address gets corrected while the person is still there to fix it.
Validate Single EmailValidate Bulk EmailsClean an imported list in one submission
Lyro submits the whole list for bulk validation rather than checking addresses one at a time, which is the difference between a single job and hundreds of separate lookups.
Validate Bulk EmailsRetrieve Batch ResultsPick a bulk job back up once it finishes
Lyro holds the batch ID and retrieves the results when the job has run, so a long list does not keep the conversation waiting on it.
Retrieve Batch ResultsValidate Bulk EmailsExplain why a campaign is bouncing
Lyro revalidates the segment that bounced and reads the batch results back, turning a bounce rate into the specific addresses that are invalid or risky.

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 Mails so actions it has and picks the ones a request needs.
- 01
Connect Mails so
Authorize the Mails so 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.
- 02
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Lyro maps it to the Mails so actions that close it and chains as many as the request needs.
- 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 Mails so
Setup, permissions, and the limits of what Lyro can do inside Mails so.
No. Validate Bulk Emails submits the list and hands back a batch ID, and Retrieve Batch Results pulls the outcome once the job has run. Lyro can carry on with the rest of the conversation and come back to the results, so list size does not block the exchange.
