So, the standard way Google would like you to setup your business email (example: firstname.lastname@example.org) is to pay G Suite $5 per month or $60 a year per user. This is not a terrible amount of money, especially when compared to other supported business email pricing (often $10 a month and up). However, if you add a few accounts, it starts to add up, especially for startups and small businesses. The landscape in tech is constantly changing, for example, 2 years ago, google apps (now G Suite) used to be free for everyone. I can be easily say that Google offers the best email experience across web and multiple devices... period. So if you can afford it, do. However, as a small business owner, I also do adore free awesome services. So, I set out to find a way to get email@example.com with a free gmail account.
After a bit of research, I found it can be done. But be warned, there is a price... convenience in setup for each account.
