Why there are multiple activation emails for one user?

What is an activation email?

An activation email is sent whenever a new user logs in with the email login widget in order to confirm that the email address belongs to them.

What if a user does not activate their email address?

In case the button within the activation email is not clicked, the email address will be placed in the Unverified User Data tab in the Dashboard. It will automatically be moved to the User Data tab once the verification is complete. We keep Verified and Unverified user data separate due to the lower average quality of Unverified data.

Using Unverified user data for marketing purposes is disabled by default in the Dashboard, however, if you wish to utilize it, you can follow this guide

How does a user end up with multiple activation emails?

Until the button in the activation email is clicked, the user will have to manually put in the email address on every connection to the network. Every time they do, a new activation email will be sent.

The reason behind it is that otherwise, if they forgot to click or deleted the first activation email, they would not be able to use their email address with Social WiFi login.
