Frequently asked questions

What is Email Hosting?

Email Hosting gives you a custom professional email address on a secure, ad-free platform. Instead of using a generic email address like @hotmail.com or @yahoo.com, you can use an email address that matches your business, e.g., @yourbusiness.com. This makes your business look more professional and trustworthy.

Email Hosting lets you to create the addresses you need for different purposes. For example, you could create ‘enquiries@yourcompanydomain’ for new customer inquiries, and a separate address for existing customers to contact you directly. You can manage all your email accounts from one central dashboard, easily create new addresses, reset passwords, and send and receive emails from anywhere.

123 Reg also gives you plenty of storage space for your emails and easy-to-use tools to help you stay organised and on top of your communications.

What are the advantages of having a custom domain-based email address?

A custom domain email address, like yourname@yourbusiness.com, gives your business a proper professional edge over something generic like Gmail. It helps you look established and trustworthy from the very first email.

Customers tend to feel more confident replying when they see your own domain, as it matches your brand and shows you're serious about what you do. Every message you send reinforces your business name, turning casual emails into a subtle way to build recognition.

Depending on the plan, you'll get extra storage and collaboration tools like shared calendars to keep your team organised. Professional email powered by Titan also comes with AI tools and inbox features to help you stay on top.

How long will it take to set up?

With no software to download and a super easy setup process, your business will be ready to start using email in a matter of minutes.

How many email addresses can I have?

There’s no limit to the number of email addresses you can create on your domain. You can add as many Titan mailboxes as you need, and you manage them all from your 123 Reg account. Each mailbox is purchased separately, and discounts may apply if you buy multiple mailboxes at once.

Do I have to own domain name to buy an email package?

No, you can buy any Professional Email powered by Titan package on its own. However, to use a custom email address, you’ll need a domain name. It’s fine if you don’t have one — you can purchase a domain at the same time as your email package.

Can I check my emails with software like Microsoft Outlook?

Yes. You can connect your Professional Email powered by Titan accounts to any email client that supports IMAP or POP, including:

  • Outlook
  • Apple Mail
  • Gmail
  • Mozilla Thunderbird
  • Mail (Windows)

For help setting up, take a look at our article: How do I add my mailbox to a third-party email client?

For details on server types, see: IMAP vs POP3.

How can I create an email forwarder?

Email forwarding can be set up through your 123 Reg Control Panel. You’ll need one active Titan mailbox on the domain before you can create a forwarder.

Email forwarding is available on Pro Plus, Premium, and Ultra plans.

For more details on email forwarders and how to set one up, see: Email forwarding explained.

Does Professional Email powered by Titan include email authentication?

Yes. All Titan email accounts are set up with SPF, DKIM, and DMARC to help verify legitimate emails and protect against spoofing and phishing.

Can I migrate my business email to 123 Reg?

Yes, you can! Migrating your business email from another provider to 123 Reg is easy. You’ll just need some key details to get started. Make sure you have your current email provider's settings, including your IMAP or POP server information, along with your username and password. This will help when it comes to moving your emails, contacts, and history.

Once you have this info, transferring your domain-based email just takes a few steps. First, let us know which email accounts you want to move. Once that’s sorted, pick an email plan that suits your business and choose the best date for the switch. We'll take it from there, allowing you to watch the migration in real time, with no interruption to your business.

Can I upgrade my package if I need more space for my custom emails?

Yes. You can upgrade to a higher Email powered by Titan plan at any time if you need more storage or extra features. Upgrades can be managed directly from your 123 Reg account.

Is spam protection included?

Yes. Spam filtering is included to help keep junk mail out of your inbox. You can adjust your spam settings to suit your preferences. Titan’s spam protection also helps block viruses, worms, and other malicious emails before they reach you. Even with this added protection, it’s still important to be cautious when opening attachments.
