Any of Call Loop 2.0's 2 triggers in the catalog, including Contact Added to List and Contact Created or Updated. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Smtp2Go when something happens in Call Loop 2.0? Any of Smtp2Go's 22 actions, including Update template, Add email, Add sender domain and Add single sender email. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Smtp2Go to Call Loop 2.0? Smtp2Go has no triggers in the catalog today, so automations start in Call Loop 2.0. If you need the other direction, ask: your agent reads Smtp2Go's API documentation and adds it. ### ### Do I have to build a connector for Call Loop 2.0 or Smtp2Go? 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 Call Loop 2.0 and Smtp2Go 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.
