What are the limits of Email HTML Inliner?
Previews are an approximation, not real Gmail, Outlook or Apple Mail, so send a test before a campaign. Remote images and fonts are not loaded in the preview, and nothing is fetched. Dark mode shows your own dark styles, or a simple inversion if you have none. Your HTML stays on your device.
