Yes. A custom domain is a hallmark of a business email address. Usually, your domain is also the name of your business (for example, [email protected]). A custom domain signals your professionalism and credibility as a business more than a generic one like “@gmail.com,” and helps promote your business to recipients. Most business email platforms, like Google Workspace and IONOS, already provide a domain in their business email plans, but some require you to have a domain first, like Proton Mail and Zoho Mail.

The overall best business email provider is Google Workspace in terms of productivity tools, usability, storage, and security. Some other good business email providers are IONOS and Hostinger if you don’t have a domain yet. If you already have a domain, Proton Mail and Zoho Mail are also good, secure options.

So far, Google Workspace offers the most email storage: 2TB on the Business Standard plan and 5TB on the Business Plus plan. Its Business Starter plan also offers 30GB of storage for each email account. Proton Mail, meanwhile, has up to 1TB of storage on the Proton Duo plan. IONOS, Zoho Mail, and Bluehost all have up to 50GB of mail storage.
