Connecting them lets a phone number that texts in become a Mailjet contact on the right list, and lets a new Mailjet subscriber get a text from your Twilio number once the number checks out. The agent builds the flow, tests every scenario and keeps it running.

Yes. The New Message Received trigger in Twilio can feed Create Contact or Add Contact to List in Mailjet, so an inbound text puts the sender on the list you choose. You decide which list and which contact details get stored. ### ### Can we check a number before texting a new Mailjet contact? Yes. On a New Contact or New Contact in List trigger in Mailjet, the agent can run Lookup Phone Number in Twilio to get carrier and line type, and only schedule a message when it is a mobile line. The lookup result can also be written back with Manage Contact Data. ### ### What can start an automation from Twilio? Any of Twilio's 4 triggers in the catalog, including New Incoming Call, New Message Received, New Call and New SMS received. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Mailjet when something happens in Twilio? Any of Mailjet's 16 actions, including Add Contact to List, Get Contact, Send Email and Create Contact. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Mailjet to Twilio? Yes. When something happens in Mailjet, your agent can act in Twilio too. This page covers both directions: Mailjet's triggers and Twilio's actions are listed here as well. ### ### Do I have to build a connector for Twilio or Mailjet? 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 Twilio and Mailjet 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.
