A/B test: Verify email notification alert

Created by: erzhtor

Motivation

Currently, when signing up with an email, a verify email is sent to the user, but user still can continue using without verification. To encourage email verification, we propose to show a non-dismissable notice banner on top with the information about emails not verified and a link to re-send verify email.

Metric and experimental design

Metric: # of users with non-verified emails who have verified emails Smaller significant change: 10% ? Significance threshold: 5% Duration/size: ?
