Business email vs Gmail for business

People asking this usually mean one of three different things, and it helps to separate them. There's the free Gmail address you already have, there's Google Workspace (which Google sells as Gmail for business), and there's business email from a web host. Two of those put your own domain after the @. That's the bit customers notice.

What is the difference?

Figures are from Google's help pages as of October 2026. Google adjusts plans regularly, so check its pricing page for current UK costs.

Why does your own domain matter more than the inbox?

Because the domain is the part you own. A Gmail address belongs to Google's domain. If a staff member leaves with the password, or the account is locked, there's not much you can do.

With your own domain, the address stays yours whichever provider runs the mailbox. You can move from host email to Workspace, or the other way, by changing your MX records, and your customers never need to update their contacts.

There's a deliverability angle too. You can only set up SPF, DKIM and DMARC on a domain you control. Those records are how receiving servers recognise your emails as genuine.

When is free Gmail good enough?

When you're testing an idea, sending a handful of emails a week, and nobody else needs access. A hobby project or a side hustle in its first month doesn't need a monthly bill.

Move on when any of these happen:

1. You have a website, and the email address doesn't match it.
2. A second person needs to answer customer email.
3. You start sending invoices or quotes, where a free address looks less trustworthy.
4. You want a newsletter, which needs proper authentication on your own domain.

Workspace or host email: which should I pick?

Pick Google Workspace if your team already works in Google Docs, Sheets and Calendar, or wants shared drives and video calls under one admin login. It's a strong product, and you're paying for the whole suite, not just the inbox.

Pick the email included with your hosting if what you need is a reliable inbox on your domain. You can still read it in the Gmail app on your phone using IMAP.
