Connect Clust and MailUp
When New Application Closed fires in Clust, your agent runs Create New Email Message in MailUp, or New Email Message in List in MailUp to Create Contact in Clust. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.

Questions
Clust and MailUp, answered
What can start an automation from Clust?
Any of Clust's 8 triggers in the catalog, including New Application Closed, New Application Created, New Application Late and New Application Progress Stage Changed. Describe the moment in plain language and your agent picks the right one.
What can your agent do in MailUp when something happens in Clust?
Any of MailUp's 25 actions, including Create New Email Message, Create New Group, Send Message to Email Address and Send Message to Group. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from MailUp to Clust?
Yes. When something happens in MailUp, your agent can act in Clust too. This page covers both directions: MailUp's triggers and Clust's actions are listed here as well.
Do I have to build a connector for Clust or MailUp?
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 Clust and MailUp 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.
