  • Team mailboxes, each with its own login and generous storage
  • Powerful webmail with conversation view, search, filters and tags

Questions & answers

Email FAQs

Can I use my own domain name for email?
Yes. Professional email is built around your own domain, so you can run addresses like [email protected] along with role accounts such as sales@ or support@. If your domain is registered elsewhere we will help you point it to us.
How good is the spam and virus filtering?
Our enterprise filter, powered by SpamExperts, averages 99.98% filtering accuracy with close to zero false positives. Every message is also scanned for viruses and malware, and we filter outbound mail to protect your domain reputation.
Will my email work with Outlook, Apple Mail and my phone?
Absolutely. You can connect over IMAP, POP or Microsoft Exchange, so it works with Outlook, Apple Mail, the Gmail app and more. On Zimbra plans, mail, calendar and contacts push to iPhone, iPad and Android and stay in sync automatically.
What is the difference between Professional Email and Zimbra?
Professional Email gives you private, ad-free mailboxes on your domain with powerful anti-spam and webmail. Zimbra adds a full collaboration suite on top: shared calendars, contacts, tasks, document storage and enterprise chat, with full Microsoft Exchange compatibility and a 100% email delivery SLA. See our Zimbra page for details.
Do you scan my email to show me adverts?
Never. We do not read your mail to build advertising profiles, we do not show ads and we do not sell your data. Your email is private, and you can export or move it whenever you wish.
Can you move my existing email across for me?
Yes. Our UK-based support gurus will migrate your mailboxes, folders, contacts and calendars across for free, with zero downtime. Your old inbox stays live until everything is verified. Just get in touch to get started.
Can I share calendars, contacts and tasks with my team?
On our Zimbra plans, yes. Share calendars and book resources like meeting rooms, keep a synced company contact directory, manage tasks and store documents in your Briefcase, all from one place.
What if I am not happy?
You are covered by our 60-day money-back guarantee. If it is not right for you within the first 60 days, we will give you a full refund, no questions asked.
