Any of PostStack's 31 actions, including Send an email, Send broadcast, Send emails in batch and Update a contact. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from PostStack to DNSFilter? Yes. When something happens in PostStack, your agent can act in DNSFilter too. This page covers both directions: PostStack's triggers and DNSFilter's actions are listed here as well. ### ### Do I have to build a connector for DNSFilter or PostStack? 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 DNSFilter and PostStack 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.
