Sign-in link
Signs a member in without a password, with a code fallback for other devices.
Subject line: Your sign-in link for Linea. Designed for Linea, a fictional saas brand. Swap the logo, colors and images for yours. Replace each {{variable}} with your own value.
Quiet button
No card, no chrome: a left-aligned note with one button, like a message from a teammate.
Code fallback
A card with the sign-in button, a typed code for other devices and the browser, place and time of the request.
Desktop handoff
A dark card under a molten banner that offers the desktop app first and the browser second.
