# Synced blocks

> Save a header, footer or any section once, use it in many templates, and change it in one place.

A **synced block** is a block or section you save once and place in as many email templates as you like. When you edit it, every template that uses it shows the new version the next time it is sent or previewed. Typical uses: a footer with your address and social links, a header with your logo, a legal notice, or a seasonal banner.

A synced block differs from a [snippet](https://docs.instantcampaign.ai/guides/email-and-templates/blocks-and-layout.md). Inserting a snippet copies its blocks into the template, and later changes to the snippet do not reach that template. A synced block stays linked.

## Save a block as a synced block

1. Open a template in the email builder.
2. Select the block or section you want to reuse. Selecting a container or columns block saves everything inside it.
3. In the block toolbar, choose **Save as synced block** and give it a name.

The block on the canvas becomes a synced block. It shows a link badge so you can tell it apart from ordinary blocks.

## Add a synced block to a template

1. In the email builder, open the **Snippets** panel and choose the **Synced** tab.
2. Click a synced block, or its **Insert** button. It is added at the end of the email, and you can move it from there.

Each card shows how many templates use the block. The search box filters by name and description.

**Insert a copy** adds the same content as ordinary blocks that are not linked. Use it when you want to start from a synced block but change it for one template only.

## Edit a synced block

To place a synced block in another email, open that email in the builder and find the **Synced blocks** group in the block panel on the left. Click a block to add it at the end, or drag it to where you want it. The Synced tab of the Snippets Library offers the same blocks, plus **Insert a copy** for an unlinked copy.

Choose **Edit** on the card in the Synced tab, or select the synced block on the canvas and choose **Edit** in the settings panel. The block opens in its own editor. When you save, every template that uses it shows the new content at its next send, preview or test send. Emails already sent do not change.

## Stop syncing in one template

Select the synced block on the canvas and choose **Detach**. The content stays in the template as ordinary blocks, which you can edit freely. Other templates keep the link.

## Delete a synced block

In the Synced tab, choose **Manage**, then **Delete** on the card. You cannot delete a synced block that templates still use: the message names those templates. Detach the block in each of them first, then delete it.

## Things to know

* **One language.** A synced block has no translations. If a template has translated versions, each one shows the synced block in its default language.
* **Email themes.** Applying a theme to a template does not restyle the synced blocks inside it. Edit the synced block to change its colours.
* **Email builder only.** Landing pages do not use synced blocks.
* **Permissions.** Anyone who can view templates can see synced blocks. Saving, inserting, editing and deleting them needs permission to edit content.
* A workspace can hold up to 200 synced blocks.
