Best Business Email Hosting in 2026
A free Gmail or Outlook address undermines a business before a customer's even opened the email — it reads as unfinished. Proper business email hosting on your own domain fixes that, and for most providers now comes bundled with calendar, cloud storage and video calling rather than sold as email alone.
We compared three providers that solve this at different price points: the two dominant productivity-suite options, and a pure email-only hosting product for businesses that don’t need the full collaboration suite attached. All three run on your own domain and support UK data residency options, but they differ meaningfully on what’s actually included beyond the inbox.

Our Top Picks at a Glance
Best Overall: Google Workspace Business Starter
Google Workspace's Business Starter plan, at £5.90 a user per month on an annual commitment (£7/month with flexible monthly billing), is the default recommendation for most small businesses simply because so many people already know how to use Gmail, Docs and Meet without training. Each user gets 30GB of pooled cloud storage, custom-domain email, and video calling for up to 100 participants — enough for most day-to-day business use.
Step up to Business Standard (£11.80/month annual) if you need more storage per user or want recording capability in Meet. For a small business whose main requirement is professional email plus basic file sharing and video calls, Starter covers the ground without paying for capacity you won't use.
Current price: £5.90/user/month on annual commitment, excl. VAT, via UK Google Workspace reseller pricing (correct at time of publication — always confirm live pricing before buying).
Best for Microsoft Shops: Microsoft 365 Business Basic
If your business already runs on Word, Excel and Teams, Microsoft 365 Business Basic keeps everything in the same ecosystem for a slightly lower price than Google's equivalent — £5.40 a user per month on annual billing, or £6.48/month paid monthly. It includes custom-domain Outlook email, web and mobile versions of the core Office apps, Teams for calls and chat, and 1TB of OneDrive storage per user.
The web-only Office apps are the main limitation at this tier — if your team needs the full desktop versions of Word, Excel and PowerPoint rather than the browser versions, you'll need Business Standard instead, which adds meaningfully to the monthly cost. For email plus lightweight collaboration inside a Microsoft-centric business, though, Basic does the job.
Current price: £5.40/user/month on annual billing, excl. VAT, per microsoft.com/en-gb (correct at time of publication — always confirm live pricing before buying).
Best Budget: IONOS Email
Not every business needs Docs, Drive or Teams — sometimes the requirement really is just "professional email on our own domain, as cheaply as possible." IONOS Email covers that directly: five email accounts with 2GB of storage each, no productivity suite attached, at a regular price of £2.50 a month (IONOS also runs an introductory rate of around £1/month for the first 12 months, which reverts afterward).
That 2GB-per-account limit is worth taking seriously before committing — it's tight if your team regularly emails large attachments, and IONOS does offer higher tiers (its Microsoft 365-based plans) if you outgrow it. But for a small business or sole trader who just wants a working inbox on their own domain without paying for a suite of tools they won't touch, it's the cheapest legitimate option here.
Current price: £2.50/month regular price, for 5 accounts at 2GB each, excl. VAT, per ionos.co.uk — an introductory discount is running at time of publication; always confirm live pricing before buying.

How to choose business email hosting
Google Workspace and Microsoft 365 both bundle document, spreadsheet and video-calling tools into the email subscription. If your business already uses separate tools for those, you may be paying twice.
Email storage limits vary enormously between providers, from 2GB on budget email-only plans to 30GB or more on suite-based plans, and running out disrupts a team quickly.
Budget email hosting providers frequently run steep first-term discounts that revert to a considerably higher renewal price, which catches businesses out at renewal time.
Moving business email to a new provider risks a period of missed or delayed messages if DNS and mail routing aren’t handled carefully.
Common questions about choosing business email hosting
Do I need to already own a domain name before setting up business email?
Yes — all three providers here set up email on a domain you own or register alongside the subscription. If you don’t have one yet, most providers let you register or connect a domain during signup.
Is Google Workspace or Microsoft 365 better for a small business?
Both cover the same core ground at a similar price. The deciding factor is usually which ecosystem your team is already comfortable with — there’s rarely a strong technical reason to switch away from whichever one you already know.
Can I use free Gmail or Outlook with a custom domain instead of paying for business hosting?
Not directly — free consumer email accounts don’t support custom domains natively. You’d need a business-tier plan (or a separate email-forwarding service layered on top of a free account) to get name@yourbusiness.com properly.
How much storage does a typical small business actually need per email account?
For text-heavy email with occasional attachments, 2-5GB is usually enough for a while. Teams that regularly send large files or need to archive years of correspondence should budget for the higher-storage suite plans instead.
Will switching business email providers break my existing email address?
No, as long as you keep the same domain — you can migrate hosting providers while keeping name@yourbusiness.com unchanged. What moves is where the mail is processed and stored, handled through a DNS and mailbox migration.
Which business email host should you actually buy?
- Google Workspace Business Starter suits most small businesses as a default choice
- Microsoft 365 Business Basic suits teams already using Word, Excel and Teams
- IONOS Email is the cheapest option if you don't need a bundled productivity suite
- Always check the regular renewal price, not just an introductory discount
For most small businesses, Google Workspace Business Starter is the safe default — familiar tools, solid storage, and video calling included for a modest per-user cost. If your business already runs on Microsoft’s ecosystem, Business Basic gets you the same ground slightly cheaper. And if all you actually need is a working inbox on your own domain without a productivity suite attached, IONOS Email is the cheapest legitimate way to get there — just budget for the renewal price, not the introductory one.
