Questions
Amplemarket and Lettr, answered
What can start an automation from Amplemarket?
Any of Amplemarket's 1 trigger in the catalog, including New Call. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Lettr when something happens in Amplemarket?
Any of Lettr's 26 actions, including Create campaign, Create webhook, Send campaign and Send Email. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Lettr to Amplemarket?
Yes. When something happens in Lettr, your agent can act in Amplemarket too. This page covers both directions: Lettr's triggers and Amplemarket's actions are listed here as well.
Do I have to build a connector for Amplemarket or Lettr?
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 Amplemarket and Lettr 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.
