Why SVG Images Fail in Email Clients

Email apps use different rendering engines and security rules. Some clients block, strip, or inconsistently display SVG in HTML email, so an SVG that works in a browser may not appear for every recipient.

For a logo or decorative graphic, provide a PNG fallback at dimensions suited to its display size. If you use a modern image format, include a compatible fallback for the email clients you need to support.

Send test messages to representative clients and devices. Check image loading, transparency against the email background, image dimensions, and the alt text shown when images are disabled.
