Frequently asked questions

Business email is a professional email service that lets you send, receive, and store emails using your own domain name. It provides a secure platform for managing business communications and gives individuals and organisations a professional, branded email address. While both free and paid email services are available, paid business email services often offer benefits such as stronger security, no advertising, more storage, and the ability to use a custom domain name for your email address.


An email domain is the same as a domain name. This is the term most often used when referring to email addresses. The email domain is what follows the ‘@’ symbol in an email address. For example, if your website is example2.com, your email domain would be “@ example2.com.”


Having an email address on your own domain improves your brand image, increases credibility, and builds trust in your company. It also provides more control over your communication, better security features, no ads, and the flexibility to customise your email experience to suit your specific needs.


The number of email addresses you can have depends on the plan you choose. With Email Essential, you can have up to 5 email addresses and 3 GB of storage for each domain. With Email Unlimited, you can have an unlimited amount of email addresses and unlimited storage.


Our email comes with an excellent built-in spam filter to keep your email secure and spam-free. Our spam filter is enabled by default, so you are protected from the day you launch your email with us.


Yes, you can add your email to your phone to check your email from anywhere. Our email hosting services are compatible with popular email clients and apps, allowing you to check and manage your emails conveniently from your mobile device. Our help centre provides step-by-step guides to setting up your custom email on your preferred mobile mail client.
