1. EmailHosting.com

Best for: Businesses wanting custom-domain email with familiar productivity basics.

EmailHosting.com pairs business email with webmail, calendars, contacts, and spam and virus protection. Its business plans include mailboxes and an admin portal for managing the team’s email setup.

The admin portal is a useful extra if you want to handle email administration alongside everyday tasks. Check the plan details to see which features and mailbox options fit your team.

2. IONOS Email Hosting

Best for: Organizations that need multiple custom-domain mailboxes.

IONOS Email Hosting provides hosted business email with personalized addresses on your own domain. It also offers multiple mailboxes and storage, so mailbox availability and space are worth comparing.

This could work well for a business setting up addresses for several people or functions. Before choosing a plan, confirm how many mailboxes it includes and whether the storage will be enough.

3. Fastmail

Best for: Teams that want business email and calendars under their own domain.

Fastmail supports business email and calendars on an organization’s domain. Teams can also create additional addresses such as sales@ and support@, making it easier to separate customer-facing functions without creating a different address for every role.

Those role-based addresses stand out for teams that want distinct inbox identities. Check how the available address and mailbox options fit the setup you have in mind.

4. mailbox

Best for: Organizations seeking hosted email alongside productivity features.

mailbox offers business email hosting with custom domain names. Its business service is designed for organizations that want email alongside related productivity tools, rather than a standalone mailbox.

That broader offering may suit a team looking for more than email in one platform. Review the current feature list to see which tools are included and whether they fit your work.

5. Hostinger Mail

Best for: Businesses that want email hosting separate from website hosting.

Hostinger Mail provides custom-domain business email separately from Hostinger website hosting. You can connect mailboxes to email apps through Hostinger’s mail connector, so check whether it works with the apps your team already uses.

The connector is worth checking before you choose. Confirm which email apps and setup options are supported on your devices.

6. Porkbun Email Hosting

Best for: Domain owners comparing forwarding and hosted email.

Porkbun Email Hosting offers custom-domain email options, including forwarding and encrypted email through its Proton Mail partnership. The range of options sets it apart, but they work in different ways.

Forwarding sends messages addressed to one address to another inbox. It is not the same as a hosted mailbox for receiving and sending email, so check which option matches your business needs.

7. EtechMail

Best for: Businesses that need email hosting with programmatic access.

EtechMail offers custom-domain business email, webmail, and a REST API. It also supports IMAP, POP3, and SMTP, which teams commonly use to connect mailboxes to email clients and other systems.

This combination may suit teams assessing integrations with existing software or custom workflows. Check the API and protocol documentation against your setup before committing.

8. DeoMail

Best for: Businesses seeking straightforward professional email on a custom domain.

DeoMail provides professional email hosting for custom domains. Its focused offering may suit a business that wants domain-based email without committing to a broader productivity platform.

The listed feature set is concise, so check the details that will matter in daily use. In particular, confirm mailbox capacity, storage, and how administrators manage accounts.

Frequently asked questions

What does email hosting do?

Email hosting runs mailboxes for an email address, usually on a domain your business owns. A custom-domain address uses your business’s domain, while a free personal email account typically uses the provider’s domain.

Is forwarding the same as a mailbox?

No. Forwarding sends incoming messages to another address. A hosted mailbox is an account for receiving and sending email. Before choosing forwarding, make sure it supports your intended sending setup as well as receiving.

What should I check before switching?

Confirm your domain setup, mailbox capacity, storage, email app compatibility, and whether the provider offers migration support. Aliases or shared addresses can help teams manage functions such as sales or support. Calendars may matter for scheduling, and API access can help connect email to software.

The verdict

Fastmail is the strongest overall pick here. It combines business email and calendars on a custom domain with additional addresses for team functions. EmailHosting.com is a runner-up for its webmail, calendar, contacts, protection, and admin portal. EtechMail is worth considering if you need API and protocol access.
