# Personalize Content Using Content Blocks
> Reuse personalized content across multiple MoEngage campaigns with content blocks. Insert blocks by selection or label for consistent messaging.
# Overview
Before starting your journey with content blocks, you must create a content block. For more information, refer to [Content Blocks](/user-guide/content/content-blocks/content-blocks).
Content blocks allow marketers to reuse the same content across multiple campaigns.

# Ways to Use Content Blocks
When you create a personalization condition or logic using the plain text editor, it appears as a chip. To know more about Chip Actions, refer [here](/user-guide/campaigns-and-channels/getting-started/message-personalization/dynamic-content-personalization).
You can use your content blocks in two ways:
* [Select the desired content block](/user-guide/campaigns-and-channels/getting-started/message-personalization/personalize-content-using-content-blocks#select-the-desired-content-block)
* [Insert the block label of your content block directly](/user-guide/campaigns-and-channels/getting-started/message-personalization/personalize-content-using-content-blocks#insert-the-block-label-of-your-content-block-directly)
## Select the Desired Content Block
1. While creating content, type @.
2. On the Personalization pop-up, click the **Content blocks** tab.
3. In the **Select content block** list, click the desired content block.
4. Turn the **Insert only the content of the content block** toggle on to insert only the content of the content block.
This means that only the content will be inserted while detaching itself from the existing content block, and no future updates will be reflected.
5. Click **Done** to insert the content block.
1. While creating content, click **Text personalization**.
2. On the Inform personalization pop-up window, click the **Content block** tab.
3. In the **Select content block** list, click the desired content block.
4. Turn the **Insert only the content of the content block** toggle on to insert only the content of the content block.
This means that only the content will be inserted while detaching itself from the existing content block, and no future updates will be reflected.
5. Click **Copy & Close** to copy the personalized attribute to the clipboard.
6. Paste the copied value in the message editor using keyboard shortcuts.
## Insert the Block Label of Your Content Block Directly
1. Copy the *Block label* from your Content Block page.
2. Paste the *Block label* into the campaign/template/another content block.
