# Customizing Your Workflow Messages

> Personalize your Cal ID workflow reminders with custom sender names, dynamic subject lines, and booking variables so every message feels on-brand.

A custom template gives you full creative control over how your reminders and notifications look. The **Default Template** is great for a quick setup, but switching to a **Custom Template** unlocks personalized sender names, dynamic subject lines, and booking variables so every message feels on-brand.

## Personalize your template

<Steps>
  <Step title="Enable customization">
    Go to the **Message template** field and select **Custom** from the dropdown. This unlocks editing for the Sender Name, Subject, and Email Body.

  </Step>

  <Step title="Set the sender identity">
    With a custom template you aren't stuck with a generic "Cal ID" name. Change the **Sender Name** to your own name, your company's name, or a specific department to build trust with your attendees.

    </Frame>
  </Step>

  <Step title="Craft a dynamic subject line">
    The subject line is the first thing attendees see. Write a catchy, relevant **Custom Subject** from scratch, and use the **Add variable** dropdown to drop in values like the `{EVENT_NAME}` or `{ATTENDEE}` name so it stands out in a crowded inbox.

  <Step title="Use variables in the body">
    To keep every email personal and accurate, use the **Add variable** dropdown in the Subject and Email Body sections. Each token below is replaced with real booking data when the message is sent.
