"john.smith@startup.com <– The founding team is all from Microsoft and can’t shake it if they tried." Alternatively, one or more members of the founding team has a name that doesn't map easily to a name + initial for English speakers. I know that jsmith@foo.com has a first name starting with J and a surname of Smith, but who is balaswaminathan@startup.com? Is that a first name and a last name, a first initial and last name, or just a last name? And where is the demarcation between first and last names? You can argue that it doesn't matter, but then why have a systematic email address at all?
