Purpose: Learn how to use Adobe Journey Optimizer’s AI Assistant to generate subject lines, refine email text, adjust tone, and create on-brand Firefly images directly inside the email designer.

Learning objectives

By the end of this module, you will be able to:

  1. Use the AI Assistant to generate subject lines and pre-headers.
  2. Refine hero text, descriptions, tone, and messaging.
  3. Apply AI-driven rephrasing, summarization, and tone adjustments.
  4. Generate images using Adobe Firefly with reference style and brand settings.
  5. Replace placeholders with generated images inside your email design.

Introduction

The AI Assistant in AJO helps you build smarter, on-brand content.
It can:

  • Generate subject lines
  • Improve existing text
  • Adjust tone and clarity
  • Create branded images using Firefly
  • Ensure everything aligns with Connection 5G guidelines

For this exercise, you improve the email that you created using the AI Assistant.

NOTE
The AI Assistant is non-deterministic, which means it may generate slightly different content each time it is used. What you see during your practice may not exactly match the screenshots or examples in this guide. That’s okay—focus on learning the process and concepts rather than expecting identical results.

Create email subject line using AI Assistant

  1. Go back to the Campaign by clicking the back button, or edit the email you created in the previous module. From the previous step, you can click the Settings tab on the right-hand side.

  2. Click on Email Container > Click on Edit Email button.

  3. Click on the content tab, and then click on Email body

  4. Select the Subject Line field.

  5. Click the AI Assistant icon. (see below)

  9. Review the four variants generated.

  10. Choose the variant with the best alignment score and click Select.

  4. As expected, you notice many errors that violate brand guidelines. Although these could be corrected using AI, in this case you don’t revise the existing materials. Instead, you leave them as they are and create new content from scratch that fully aligns with brand standards.

Add a Firefly-generated image

Until now, we have tested AI Assistant on Subject line and Text. What about images?

Before diving into AI image generation, look at what types of experiences you can build.

We understand that we have the year of birth of the profile. One of the experiences we can do is to create a block with different variants. With Adobe Journey Optimizer, this is possible and one of the biggest advantages of having Adobe Experience Platform as your base. We will cover experimentation in our next module, but first, prepare the block below.

  1. Drag an Image component to the left-hand side column below iphone 17 Family block.

  3. Under Firefly, click Generate and select image.
