Nothing undercuts a quotation faster than sending it from a free webmail address. Professional Email gives you mailboxes at your own domain — yourname@yourcompany.com, sales@, accounts@ — so every message you send reinforces your brand instead of someone else's. For SMEs and freelancers competing for trust, especially in markets where customers are wary of impersonation and fraud, a domain-matched address is one of the cheapest credibility upgrades available.
The core product, running on GoDaddy's email infrastructure, covers what a small business actually needs: webmail access from any browser, synchronisation with phone and desktop mail apps, calendars and contacts, and built-in spam and virus filtering. Setup is guided, and because the mailbox is tied to your domain's DNS, it works no matter where your website is hosted — you can keep a site elsewhere and still run email through your ATCOS Domains account.
When a team grows past basic correspondence, the natural step up is a Microsoft 365 plan, which GoDaddy also provisions: the same custom-domain mailbox plus the Office applications — Word, Excel, PowerPoint, Teams — and OneDrive cloud storage. Agencies and consultancies in the UK, Ireland, and the Netherlands in particular tend to standardise on Microsoft 365 early because their clients already live in it.
Ordering email through ATCOS Domains means mailboxes, domains, and DNS live under one roof, so the fiddly part — MX records, autodiscover, verification — is handled inside a single account rather than coordinated across providers.

Frequently asked questions
How much storage does each mailbox include?
Storage quotas differ by plan tier — entry-level Professional Email mailboxes carry a smaller allowance, while higher tiers and Microsoft 365 plans include substantially more, with current figures shown on the storefront at purchase. For context, a typical small business exchanges years of ordinary correspondence within even the entry quota; heavy attachment users should size up or lean on cloud storage links.
Can I move my existing Gmail or Outlook.com history into the new mailbox?
Yes. The usual approach is IMAP migration: connect both accounts in a desktop client or migration tool and copy folders across, preserving your archive. Going forward, set your old address to forward to the new one and update key contacts and account logins gradually. Most small mailboxes migrate in an hour or two of mostly unattended copying.
My website is hosted with another company — can I still use this email?
Absolutely. Email delivery is controlled by your domain's MX records, which are independent of where the website lives. You point the MX records at GoDaddy's mail servers — guided setup handles this if your domain is in the same account — and the website keeps running wherever it is. Split configurations like this are completely routine.
What is the difference between Professional Email and Microsoft 365?
Professional Email is the lighter product: custom-domain mailboxes with webmail, sync, calendars, and filtering. Microsoft 365 includes a custom-domain mailbox too, then adds the Office desktop and web applications, Teams, and OneDrive storage. Choose Professional Email if you only need credible email; choose Microsoft 365 once your team collaborates on documents or holds video meetings.
