In this article we will tell you the various ways you can add a "pop up" window / message to your Infigo storefront. 

You have a couple of different options: 

Within Configuration > Settings > Customer Settings > and under the first tab 'customer settings' and within the first section, you'll see "Show message after login:" which you can enable. This will display a message to the user after login.
 

 
Once you enable this, you can go to the customer account and there will be an additional tab called Login Message. The same option is available for Department.
 
Alternatively you could put a note in the page(s) header in editable content. https://infigosoftware.zendesk.com/hc/en-us/articles/200872838-Editable-Content 
 
We also have a per storefront setting within editable content called Storefront.LoginMessage which you may want to use.
