Questions
PostStack and Front, answered
What can start an automation from PostStack?
Any of PostStack's 7 triggers in the catalog, including Contact Updated (instant), New Contact (instant), New Inbound Email and New Sent Email (instant). Describe the moment in plain language and your agent picks the right one.
What can your agent do in Front when something happens in PostStack?
Any of Front's 28 actions, including Create Account, Create Contact, Create Draft and Create Draft Reply. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Front to PostStack?
Front has no triggers in the catalog today, so automations start in PostStack. If you need the other direction, ask: your agent reads Front's API documentation and adds it.
Do I have to build a connector for PostStack or Front?
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.
