Can anyone describe me if you can find out if an E-MAIL address belongs to a company?
Answers:
Today, almost every legal company owns a domain label, which it uses for its website and its email.
For example, Microsoft Corporation owns the 'domain moniker' call "microsoft.com" -- This domain dub is used contained by its website address -- www.microsoft.com -- and within its email, such as info(a)microsoft.com and bill.gates(a)microsoft.com --
Therefore, if the company's domain dub is used for its email, afterwards you are assured that the email address belongs to the company.
Conversely, you should not trust that an email address belongs to a company, if the email address does not contain the company's domain first name. For example, you should not trust a personage who claims to work for Microsoft Corporation but who give you an email address close to john.jones(a)aol.com --
Finally, if you want positive proof, find the verified mobile phone number of the company and telephone call its most important switchboard.
Hope this help.
