Media Library#

The Media Library stores images and other files used in your campaigns and templates. Uploading an image once and reusing it across campaigns is faster than attaching the same file every time — and it lets you update a single asset everywhere it appears.

Uploading#

Upload files from Pulse → Media or directly from the campaign editor when inserting an image.

• Drag and drop, or click to select
• Multiple files can be uploaded at once
• Supported image formats: JPEG, PNG, GIF, WebP, SVG
• Other supported formats: PDF, ZIP
• Maximum file size: 25 MB per file

Uploaded files receive a permanent URL. That URL remains stable even if you rename the file, so links in sent campaigns continue to work.

Organizing#

Files can be organized with:

• Folders — group files by campaign, product, or quarter
• Tags — attach freeform labels for cross-folder search
• Search — match on filename, tag, or alt text

Image Variants#

When you upload an image, Pulse automatically generates responsive variants at multiple widths. The campaign editor uses the smallest variant that fits each recipient’s device, reducing email size and improving load times.

Hotlink Protection#

Files in the Media Library are served from Pulse’s CDN. Hotlinking — embedding these URLs in websites or apps outside Pulse — is allowed but counts toward your workspace’s bandwidth quota.

If hotlink traffic becomes excessive, you can enable domain restrictions so the CDN serves the file only when referred from a configured list of domains.

Storage Limits#

Deletion#

Deleting a file removes it from the library immediately. Campaigns that were already sent keep their copy — recipients will still see the image. Scheduled campaigns that reference the file will break: the editor highlights any missing media when you open the campaign.
