Short answer

How can I use my AI to make personalized emails?

Your AI takes your Handlebars templates and fills them with specific customer details. You get production-ready email text that matches your brand's structure. Here is how the process works.

Where every email lands.

The outcomes of your request.

Depending on how you prompt your agent, you'll get different results.

READY

Final email copy

The AI uses the compiler to produce the full text. You get a finished message ready for your email service provider.

DATA

Merged customer profiles

The AI maps your raw data to the template variables. This ensures names, dates, and preferences land in the right spots.

REVIEW

Human-in-the-loop check

The AI presents the rendered text for you to read. You decide if the tone and data accuracy meet your standards.

LOGS

Template validation

If a variable is missing, the AI flags the error. You get clear feedback on why a template failed to compile.

The workflow

What your AI does when the data arrives.

The AI acts as the bridge between your raw data and your design.

  1. Read templates

    Your agent pulls the Handlebars logic from your files to understand the required variables.

    compile_template

  2. Map customer data

    The AI looks at your customer list and matches the fields to the template placeholders.

    compile_template

  3. Execute merge

    The compiler runs the logic to swap out the curly braces for real customer information.

    compile_template

  4. Verify output

    The AI checks the final string to ensure no empty placeholders or broken logic remain.
