How Assembly Reduced Support Requests with Last-Used Email Displays

A common problem for apps like Photo AI is users forgetting which email address they used to sign up. This leads to frustrated customers and repetitive support tickets.

The Problem: Forgotten Emails Create Unwarranted Support Requests

Users often sign up with multiple email addresses or Google accounts, especially without password managers. For example, Photo AI customers repeatedly reported:

  • “I paid but can’t log in.”

  • “I’m stuck in a loop where login attempts trigger new activation emails.”

In one case, a user’s subscription was active, but they couldn’t access their account. Every login attempt sent a new signup email, creating confusion. The root cause? They were using the wrong email address.

The Fix: Show Users Their Last-Used Email

The solution, inspired by Assembly, involves storing the user’s login details securely:

  1. Save the email after login: When a user logs in successfully, save their email and login method (e.g., Google, email/password) in a cookie.

  2. Set an expiration date: Cookies expire after 60 days for privacy purposes.

  3. Display it clearly: On the login page, show a message like “Last signed in as: [email protected].

Assembly - Last Used Email

For example, after implementing this, Assembly’s login page displays: “Last used: [email protected]

The alternatives are using local storage instead of cookies for longer persistence or showing Stripe receipt instructions (e.g., “Search your inbox for ‘Your receipt from Photo AI’”) using AI ChatBot.
