Short answer

How can I send emails or broadcasts via my AI?

You can trigger specific emails to individuals or launch broad messages to entire segments using natural language. Your AI handles the execution through Customer.io once you give the command. You'll see how the logic flows below.

Messaging outcomes

What you can trigger

The AI maps your text commands to specific Customer.io actions.

MASS

Group broadcasts

The AI sends a message to an entire segment at once. This is how you handle announcements or updates.

Human oversight

The AI won't just blast your list. You'll review the intended recipient or segment before the final send.

FAQ

How this task behaves

  • 01

    Can the AI write the email content for me?

    No. The AI uses the templates already existing in your Customer.io account to send the messages.

  • 02

    Will it send messages without me seeing them first?

    No. Your AI client will show you what it intends to do, allowing you to confirm the recipient or segment before it executes.

  • 03

    Can I use this to create new segments?

    No. This connector is for sending messages to existing users or segments, not for managing segment logic.

  • 04

    Does the AI have access to my full customer database?

    The AI only accesses the specific user or segment data required to fulfill your command.

  • 05

    Can the AI delete users from Customer.io?
