MailUp and Writer, answered
What can start an automation from MailUp?
Any of MailUp's 4 triggers in the catalog, including New Email Message in List, New Group, New Recipient Subscribed and New Recipient Unsubscribed. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Writer when something happens in MailUp?
Any of Writer's 16 actions, including Send Prompt, Update knowledge graph, Add file and Add file to knowledge graph. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Writer to MailUp?
Writer has no triggers in the catalog today, so automations start in MailUp. If you need the other direction, ask: your agent reads Writer's API documentation and adds it.
Do I have to build a connector for MailUp or Writer?
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.
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.
