Magic link email

A short passwordless sign-in email: clearly states that the link is temporary, private, and leads only to the account.

When the user requests sign-in or registration via magic link.

Owner note

This is the most functional email. Minimal atmosphere, maximum clarity.

{{magic_link}}{{expires_in}}{{support_email}}

Fallback

If the link expires, CTA should lead to /login or recover flow, not support as the first step.

Do this

Say that the link is one-time or temporary.
Warn the user not to forward the email.
Give a support fallback.

Avoid this

Do not add promo blocks before the sign-in button.
Do not repeat the user's email in the body unless needed.
Do not make the email feel like a reading.
