Keep it simple
Use clear and direct language to ensure that the purpose of your email is understandable.
Outline how it works
Some people may not be used to passwordless access, so briefly explain how they work and their shelf life.
Log in with one click
Include a button with an authenticated and automatically generated URL, to allow the user to log in with a single click.
Allow feedback to be sent
It is probably not possible to reply to the email sender account, so provide another way they can contact you.
Call them by their name
If you have their name stored in your database, you can include the variable on the email to further personalize it.
Completely customize it
Feel free to edit colors, fonts, the logo... and adapt the look and feel of this email to your brand’s style guide.
