Create a default contact property to indicate whether contact's using free email domain

Hey team,
Currently, HubSpot keeps a list of disposable domains here.

It would be really useful if we have a standard property that can effectively track whether a contact is using one of these emails. We can use a list, but list has limited processing size. As such, it will not work well with a filter that include thousands of values.
Thank you!

+1. We setup an active list using the Email CONTAINS and all the values in that HubSpot article. This is so that we can identify all the non-company leads for segmenting in our campaigns, as well as analyze the effectiveness of our enrichment tool (i.e. how many personal emails were able to get enriched with company and job title).

However, we discovered that this list is not processing correctly due to the limited processing size. But there is no error warning to let us know that. I just found out by talking to HubSpot Support (YiRui_Chua).

This feature request would address the problem.
