Joining them means a new signup in Mailjet can be handed to Claude for a draft or a summary, and the result can be written onto the contact record or sent straight out as a Mailjet email.

Yes. Take the reply from Send model a message or Anthropic agent message and write it into a contact property with Manage Contact Data, after Create Contact Property has set that property up once. ### ### Can something in Anthropic start a workflow in Mailjet? No, Anthropic has no triggers, so every run starts in Mailjet from a new contact, a contact newly added to a list, or a new contact list. Anthropic steps then run as actions inside that same run. ### ### What can start an automation from Mailjet? Any of Mailjet's 3 triggers in the catalog, including New Contact, New Contact in List and New Contact List. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Anthropic when something happens in Mailjet? Any of Anthropic's 9 actions, including Anthropic agent message, Count tokens in a message, Create message batch and Send model a message. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Anthropic to Mailjet? Anthropic has no triggers in the catalog today, so automations start in Mailjet. If you need the other direction, ask: your agent reads Anthropic's API documentation and adds it. ### ### Do I have to build a connector for Mailjet or Anthropic? 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 Mailjet and Anthropic 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.
