Why SVG Isn't Supported
SVG files can contain executable code. Because uploaded images are served from a public web address, allowing SVGs would create a security risk. Export your graphic as PNG instead.
Keeping Images Small
- Most email layouts are around 600px wide — there's rarely a reason to upload anything larger.
- Compress images before uploading. A smaller file loads faster for recipients and lowers the chance of an email being flagged as spam.
- Uploading the same file twice doesn't cost extra storage — duplicates are detected automatically and reuse the existing copy.
See Adding Images to Your Emails for how to upload, and How Score Protects Your Uploaded Images for how images are secured.
