# Personalize Your WhatsApp Session Messages in Marketing Cloud Engagement

Use Content Builder to create session messages to respond to user-initiated conversations. When a user sends a message to your WhatsApp channel, you can respond without using a template. Session messages are free-form messages and don’t need approval.

1. In Content Builder, click **Create**.
2. In the dropdown, select **Chat Messaging**, and then select **WhatsApp Session Message**.
3. Select the message type from the dropdown.
4. Complete the message body using personalization tags.
    
    A session message can be up to 4,096 characters, including personalization and emoji. Facebook rejects messages that exceed these limits.

    Note If you’re using an AMPscript string, define it within the personalization fields.
5. To add media, upload a JPG, PNG, PDF, or MP4 file.
    
    You can attach media as a file or public website. For size restrictions, see [WhatsApp Media Attachments in Marketing Cloud Engagement](https://help.salesforce.com/s/articleView?id=mktg.mc_jb_whatsapp_media_attachments.htm&release=264.0.0&type=5 "To send a media message with WhatsApp, attach a media file in the message header. The recipient can open and save the attachment independently of the WhatsApp message. For all message types, you can include an image, document, or video file. You can include an audio file only with a session message.").
6. Save your changes.
