In the middle of app use, Pinterest prompts the users with a slideout modal, asking whether the user is still using the same email address. It also refers to the users by their first name.

Why it’s great:

‍

✅ Personalization - Pinterest uses personalization by referring to users by their first names, which encourages users to interact with the modal.

✅ Friendly feel - The slideout modal’s copy reads as if it’s a text from an old friend; this, too, is an element to make users interact with the onboarding.

✅ Not too intrusive - as it is the nature of a slideout modal, it doesn’t cover the entire screen, and even though it blocks the content, it doesn’t feel as intrusive as a full-screen modal.
