Questions
MailCheck.ai and User.com, answered
What can start an automation from MailCheck.ai?
Any of MailCheck.ai's 4 triggers in the catalog, including Domain added to blocklist (instant), Domain flagged as relay (instant), Domain flagged as spam (instant) and Domain unflagged as spam (instant). Describe the moment in plain language and your agent picks the right one.
What can your agent do in User.com when something happens in MailCheck.ai?
Any of User.com's 4 actions, including Create Event, Create/Update Company, Find Company and Find User. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from User.com to MailCheck.ai?
Yes. When something happens in User.com, your agent can act in MailCheck.ai too. This page covers both directions: User.com's triggers and MailCheck.ai's actions are listed here as well.
Do I have to build a connector for MailCheck.ai or User.com?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use MailCheck.ai and User.com without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
