Subject & preheader

Subject suggestion
Your Northstar sign-in link
Preheader
Use this link within 15 minutes to sign in.

Set the subject in your sending tool. The preheader is already in the HTML.

Make it yours

  • Replace the sample URL with a short-lived, single-use sign-in URL.
  • Do not put the real sign-in token in the subject or preheader. Set the lifetime to match your server.

All names, products, amounts and dates are examples. Replace the brand, sample copy and every example.com link in both files. Changes in the viewer do not update the separate plain-text file.
