Bank accounts and email addresses with Multiple LLCs

[Sunil Kapoor]

Hi All,

I currently have 3 LLCs managing my properties, and those 3 LLCs roll up into a "holding entity" LLC, taking my LLCs to 4 in total.

I understand that I need 4 separate bank accounts to prevent co-mingling of funds, but in addition each of the LLCs is communicating the property managers/mortgage companies/etc.  

Therefore, should I also have 4 separate email addresses that each LLC uses to communicate to the various property managers/mortage companies/banks/etc?

That seems like overkill, but just want to check
