What is the best way to host images for email campaigns?

Use the built-in Media store

Pushwoosh includes a Media store — a per-project image library. Upload an image once and reuse it across push notifications, web push, emails, in-app messages and Cloud Pages, either directly in the editor or via a stable URL.

To open it, go to Content → Media store in the Pushwoosh Control Panel.

• Supported formats: JPG, PNG, WebP and GIF. Other file types are ignored.
• Size limits: JPG, PNG and WebP up to 5 MB each; GIF up to 10 MB.
• You can upload up to 5 images at a time.
• You can create resized/cropped variants of an image at different aspect ratios for different placements.

Important: deleting an original image also deletes all of its variants, and any already-sent email that references the URL will stop loading it. Do not delete images that may still be rendered in mail clients.

When to use an external host instead

Uploading an image into an individual email preset and copying the generated link is not a good long-term approach — if the image inside that preset is later replaced, the link may stop working.

If you need full control over retention, versioning or your own CDN domain, host images externally:

1. Choose a host — a CDN such as Cloudflare, cloud storage such as Amazon S3 or Google Cloud Storage, or your own web server.
2. Get the direct public URL of the uploaded image.
3. Insert it into the src attribute of the <img> tag in your email HTML.

Whichever option you pick, use a URL that will stay valid indefinitely — emails already delivered will keep requesting it.
