Gmail always rejects the first email I send to a new gmail account. It does this every time – and has done for years – despite the fact I have sent emails to hundreds of other gmail accounts, and send emails to such accounts every day.

This is the reason I personally will not touch any Google services. And in business, I excise Google services as a priority. If a company cannot handle email in a civil manner, it certainly can't be trusted with anything of importance.
