Mem0 passwordless sign-in email

Why it works

• Make the login action the central focus with one clearly labeled sign-in button.
• Place the link's expiration and single-use details near the action so recipients know what to expect.
• Include a plain-text fallback and concise security guidance for people who cannot use the button or have concerns.

How it is built

1. Brand header
2. Sign-in prompt
3. Primary button
4. Link expiration note
