What does Mailboxlayer actually check?

An address's syntax, its domain, the receiving mail server's SMTP response, and quality meta-flags such as whether it looks disposable - Lyro reports all of it from a single check.

Can Lyro fix a bad email address automatically?

No - it flags what's wrong with the address so the conversation can correct it. Mailboxlayer validates; it doesn't guess the intended correct address.

Does the check confirm the inbox actually exists, or just that the domain is real?

Both are part of the result: the domain check confirms the domain accepts mail, and the SMTP response step goes further to check the receiving server's reply for that specific address.

Can an email check run alongside other data Lyro looks up in the same conversation?

Yes - each integration works independently, so a Mailboxlayer check can be one step in a conversation that also touches other tools Lyro is connected to.

How businesses use Mailboxlayer + Lyro

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

Catch a mistyped email before it bounces
When a customer provides an email address, Lyro checks it against Mailboxlayer's syntax and domain rules and flags anything that looks wrong before it's saved.
Check Email ValidityVerify SMTP Response
Explain why a confirmation email never arrived
If a customer says they never got an email, Lyro can check the address through Mailboxlayer's SMTP response to see whether it was ever deliverable.
Check Email ValidityVerify SMTP Response
Confirm an address before an account update
Before an email address change goes through, Lyro validates the new address so the account isn't updated to something that will bounce.
Check Email ValidityVerify SMTP Response
Flag a disposable or low-quality address
Mailboxlayer's quality meta-flags let Lyro point out when an address looks disposable or otherwise low-quality, not just syntactically valid.

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

01
Connect Mailboxlayer
Authorize the Mailboxlayer 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 Mailboxlayer 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.
