Can Lyro send a campaign or add a subscriber through Mailercloud?

No. The six actions cover list creation, contact search within a list, and custom property management. There is no send action and no contact-create action, so despite what the connector blurb suggests, campaign sending and contact import stay in Mailercloud.

Is there a ceiling on the custom properties Lyro can create?

Yes, Mailercloud allows a maximum of 100 custom properties per account. Update Contact Property can also only change a property's name and description - the property type is fixed once created, so a wrong type has to be deleted and recreated.

What happens if Lyro tries to delete a property a webform uses?

The delete fails. Delete Contact Property cannot remove a property that is referenced by a webform, so the field stays in place until the form is changed. Lyro reports the refusal rather than silently skipping the request.

How is this different from wiring Mailercloud into Zapier or Make?

Those fire a fixed sequence when a trigger matches. Lyro decides in the conversation whether a list already exists, searches it before creating anything, and checks the plan first - chaining several calls in one exchange rather than following one predefined path.

How businesses use Mailercloud + Lyro

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

Stand up a list for a new segment
Lyro creates the recipient list, adds the custom properties that segment will be filtered on, and confirms the plan can carry it before anyone starts importing contacts.
Create ListCreate Custom PropertyGet Client Plan
Check whether a contact is already on a list
Lyro pages through a known list to find whether the person in the conversation is already subscribed, which stops the same customer being added twice under two spellings.
Search Contacts in ListCreate ListGet Client Plan
Keep custom contact fields from sprawling
Lyro renames the properties whose labels no longer match what they store and deletes the ones nothing references, keeping the field set inside the account's property allowance.
Update Contact PropertyDelete Contact PropertyCreate Custom Property
Confirm the account can take the send
Before a campaign goes out, Lyro reports the current plan and subscription status against the size of the list it would target, so a send is not planned past what the account allows.

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

01
Connect Mailercloud
Authorize the Mailercloud 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 Mailercloud 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.
