What is the Block Library?

The Block Library is where you find every block you can add to an email in Instant AI. It holds your own saved blocks (images, HTML, rich text and layouts) and the ready-made Instant blocks that use your Brand Kit.

Why you need it

  • Images you upload are saved here, so you can reuse them in any campaign, flow email or template.
  • Blocks you have used in your emails are saved here, so you do not need to build them again.
  • Without it, you would need to upload the same image again each time you build an email.

How to open the Block Library

You can open the Block Library from campaigns, flow emails and email templates.

  1. Open the campaign, flow email or template you want to edit
  2. In the left panel, find Add blocks
  3. Click View library

The Block Library opens on Images.

Tip: You can also open it from an image. Select an image in your email and click Add image or Replace image. When you open it this way, you choose one image to use.

What’s in the Block Library

The menu on the left has three parts.

  • Your library: blocks you have saved. These are Images, HTML, Rich text and Layout.
  • Instant library: ready-made Instant blocks, for example Header, Hero, Product, Review and Footer. Some categories only show for some flows.
  • Unused Blocks: saved blocks that no email uses.

Each category shows how many blocks it has.

What the label on each card means

Each card has a label at the bottom.

  • Instant generated: a ready-made Instant block.
  • Used on X emails: a saved block, and the number of emails that use it.
  • Unused: a saved block that no email uses.

How to add blocks to your email

  1. Open the Block Library
  2. Select a category in the left menu
  3. Click each block you want to add. You can select more than one.
  4. Click Insert. The button shows how many blocks you selected, for example Insert 3 Blocks.

After you select one block, you can click Select all to select every block in the category. To start again, click Clear.

How to upload images

  1. Open the Block Library
  2. Select Images under Your library
  3. Drag your images onto the upload area at the bottom, or click choose files to select them from your computer

You can upload up to 10 images at a time. Each image can be up to 10MB, in JPEG, PNG, WebP or GIF format.

New uploads show at the top of your images and are selected for you, so you can click Insert to add them straight away.

Note: Large images and GIFs can load slowly in inboxes. For recommended sizes, see What’s the ideal image size for my emails?

How to favourite a block

  1. Open the Block Library
  2. Find the block you want
  3. Click the star in the top right corner of the card

The block moves into a Favourites section at the top of that category. To remove it, click the star again.

You can favourite your own saved blocks and Instant blocks.

How to sort your saved blocks

  1. Open the Block Library
  2. Select a category under Your library
  3. Click the sort option next to the section title
  4. Select Most used, Newest or Oldest

Most used is the default. The Block Library remembers your choice the next time you open it.

How to delete unused blocks

  1. Open the Block Library
  2. Select Unused Blocks at the bottom of the left menu
  3. Click each block you want to delete. After you select one, you can click Select all to select every unused block.
  4. Click Delete. The button shows how many blocks you selected.
  5. Confirm that you want to delete the blocks

Note: You cannot undo a delete. Blocks from campaigns you have already sent can show in Unused Blocks, so check each block before you delete it.

FAQ

Why does the same image show more than once? The Block Library saves blocks, not image files. If you use the same image with a different link, padding or style, it is saved as a separate block. Blocks that look exactly the same show as one card.

Why can I not see my favourites on a different computer? Favourites are saved in your browser. They do not show for your teammates, on a different browser or device, or after you clear your browser data.

Which emails does “Used on X emails” count? It counts flow emails and campaigns that are not sent yet. Campaigns that are already sent are not counted, so a block from a sent campaign can show as Unused.

Can I search my images? No. To find an image, sort by Newest, Oldest or Most used, or add the images you use most to your favourites.

If I edit an image, does the original change? No. When you crop or edit an image from your library, Instant saves the edited version as a new image. The original stays in your library. For more, see How to edit or crop an image in Instant AI.
