## Library

> Store and manage images and assets your templates reference.

The Library is shared asset storage for your workspace — upload images and files once, then reference them from any template. Hosting assets here (rather than hot-linking from elsewhere) means they stay available and load fast for every recipient.

Assets are referenced by Templates, so deleting an asset that a live template uses will leave a broken image in that mail. Check usage before removing anything you're unsure about.

> **Keep originals reasonable:** Large images slow rendering and can trip spam filters. Upload appropriately sized assets — the Library is for delivery, not as a full-resolution archive.
