Saved Blocks

Create reusable, linked content blocks you can drop into any email — edit one and every email that uses it updates automatically.

Saved blocks let you build reusable content sections — a header, a footer, a call-to-action — once and insert them into any email. Unlike a copy-paste snippet, a saved block stays linked: when you edit the block, every email that uses it updates to match. Change your footer in one place and every template and transactional email carrying it re-renders with the new version.

Why use saved blocks

  • Consistency — your brand header and footer look identical across every email.
  • Speed — drop in a polished CTA section in seconds instead of rebuilding it.
  • One-edit maintenance — because inserted blocks are linked, fixing a typo or swapping a logo in a saved block flows out to every email that uses it. No hunting through old templates.

How linked blocks work

When you insert a saved block into an email, the editor doesn't paste a static copy — it inserts a linked instance. Each instance remembers which saved block it came from, and the editor marks it with a Linked block label (carrying the block's name) above the content.

What that means in practice:

When you…What happens
Edit a saved block's contentEvery template and transactional email that uses it is updated and re-rendered to match.
Rename a saved blockThe label shown on every linked instance updates to the new name.
Delete a saved blockIt is detached from every email that uses it — those emails keep the content as a normal, now-independent block.
Detach a linked instanceThat one email gets an independent copy and stops receiving updates from the library.
Edits cascade

Editing a saved block's content changes every email that already uses it. This is the point of saved blocks — but it means a careless edit can alter live templates. If you want a one-off variation, detach the instance first (see below) so your change stays local.

The re-render of consuming emails happens in the background. After you save a content change, the affected templates and transactional emails are marked stale and re-rendered shortly after by a retrying render pool — so it may take a moment for an email's rendered HTML to catch up.

Saving a block

Saved blocks are created and edited from the Mail > Blocks page.

Open the Blocks page

Go to Mail > Blocks and click New Block.

Name it

Give the block a descriptive Name (e.g. "Standard Email Header" or "Product CTA with Image") and an optional Description. The description helps you and your teammates pick the right block later.

Build the content

Click Create Block — this creates the block and opens a dedicated block editor where you add and arrange its content. The saved block can be a single block or a group of several blocks. Your changes are the block's content.

A saved block can hold one block or many. Multi-block groups show a small N blocks badge on the Blocks page so you can tell them apart at a glance.

Inserting a saved block

Insert saved blocks from inside the Email Editor using the slash menu.

Open the slash menu

Type / where you want the block to go.

Find your block

Scroll to the Saved group at the bottom of the menu, or start typing part of the block's name to filter the list.

Insert it

Select the block. It's inserted as a linked instance right after the block you're on (or at the end of the document), marked with its Linked block label.

Detaching a linked instance

To turn a linked instance into an independent copy, click the Detach icon on its Linked block label and confirm. The detached block keeps its current content but stops receiving updates from the saved block library.

Managing saved blocks

Open Mail > Blocks to see every saved block. You can search by name or description, and sort by Most Recent, Most Used, or Name (A-Z). Each block shows its usage count (how many emails currently link to it) and, for multi-block groups, a N blocks badge.

Per block, you can:

  • Edit Content — open the block editor to change what's inside (this is the edit that cascades to every linked email).
  • Settings — rename the block or update its description.
  • Duplicate — create an independent copy (named "… (Copy)") to use as a starting point.
  • Delete — remove the block from the library.
Deleting a block in use

Deleting a saved block that's used by one or more emails will warn you first. On delete, the block is detached from every email that uses it: those emails keep the content as an independent block, but it's no longer linked to anything.

Best practices

  • Save your header and footer early — these are the blocks you'll reuse most, so set them up before building your first campaign. Edit them once and every email updates.
  • Keep blocks focused — a "Header" block should just be the header, not the header plus the first content section. Smaller blocks are more versatile.
  • Name blocks descriptively — "Holiday Sale CTA (Red)" is better than "CTA 2". The name is also what shows on every linked instance in the editor.
  • Detach before customizing — if one email needs a tweaked version of a shared block, detach that instance first so your change doesn't cascade to everyone else.
  • Review periodically — use the Most Used sort and the usage count to spot unused blocks, then delete them to keep the library clean.
