So recently we have been redesigning our login page for our b2b product. You can go to a url, login using an email and password and then you're on the dashboard. Our sales team is pushing that we place a pop-up advertisement for our new products when users open the login page. For me, the problem is that the user would only visit this url if they purchased one of our products already in order to login. Personally, I am against the idea of placing our own advertisements on a page where the user already purchased to gain access to. Additionally, having this pop-up every time the user signs in may cause some user frustration.
We have discussed banners, but the sales team is insisting on a "in your face" kind of advertisement. Our current login page is already very busy. We have the login page on the left and a different line of devices on the right with a link that takes you to a different login screen. Here is a blurred out screenshot with the grey blocks hiding logos or sensitive urls.
I won't post a screenshot of the pop up because its just standard, but just imagine a popup with a button to "View Product" for whatever new product we want to advertise
Is there a way I can meet the requirements of the sales team (placing an advertisement for our newest product) without interrupting the user experience as much? I am considering a loading screen in between the login page and the dashboard kind of like a splash screen, but sometimes the screen would load in 1 second, not giving the user enough time to click "view product" in case they wanted to purchase through the advertisement.
