Each email hosting service in brief

1. Google Workspace Gmail

Google Workspace suits teams that want a written uptime commitment, 24/7 phone and email support and admin sign-in controls, including security keys and enforced two-step verification. It supports IMAP, POP, CalDAV and CardDAV. The catch is price: $35 a month for five people, with no free plan on your own domain. Google also reported that in 2025 a threat actor used compromised tokens of a third-party integration to access email in a very small number of accounts.

Best for: Small teams that want a written 99.9% uptime commitment and detailed sign-in options. Prices, facts and sources

2. Zoho Mail

Zoho Mail suits small teams on a tight budget: $5 a month for five mailboxes on Mail Lite, plus a free plan for up to five users. Mail Lite includes SAML SSO, aliases and 24x7 chat and phone support. The catch: yearly billing only, 5 GB per mailbox, and Zoho's terms contain no uptime credits.

Best for: Small teams that want a low price and are happy to pay a year at a time. Prices, facts and sources

3. Infomaniak Mail Service

Infomaniak suits small teams that want mail hosted in Switzerland, with calendars, IMAP and a free migration service. Storage is unlimited and the company holds ISO 27001. The catches are the lack of a written uptime commitment, prices listed in Swiss francs only, and 2FA that the pages tie to the Infomaniak account rather than to each mailbox.

Best for: Small teams that want Swiss-hosted mail with calendars and a free way to start. Prices, facts and sources

4. Fastmail

Fastmail suits small teams that want a 50 GB mailbox with open protocols on their own domain. Standard includes shared calendars, a shared address book and security-key sign-in. The catch: the terms contain no uptime commitment, and its business and help pages describe no single sign-on or admin-enforced two-step sign-in.

Best for: Small teams that want mail, calendar and contacts that work in any standard app. Prices, facts and sources

5. Rackspace Email

Rackspace Email suits small teams that want to pay month to month and reach support by phone. Its mailboxes hold 25 GB, and admins can require two-step sign-in per domain. The catch is price: $10 per mailbox is high for 5 users, and calendars need a paid add-on.

Best for: Small teams that want month-to-month billing and phone support. Prices, facts and sources

6. Purelymail

Purelymail suits small teams and tinkerers who want the lowest price for many users and domains, and who use standard mail apps. It supports IMAP, POP3, CalDAV and 2FA with security keys. The catches are no written uptime commitment, no listed certifications, no per-mailbox storage figure and no shared address books.

Best for: Small teams and hobbyists who want a very low price and use their own mail apps. Prices, facts and sources

7. IONOS Email

IONOS Email suits small teams that want a big mailbox and phone or chat help at a low introductory price. Two-step sign-in with an authenticator app is available. The catch: the plan is shown only on a 3-year term, the later price is not stated, and the terms give no uptime credit for email.

Best for: Small teams that want a large mailbox at a low introductory price. Prices, facts and sources

8. Hostinger Business Email

Hostinger Business Email suits small teams that want very low per-mailbox prices and accept a 48-month commitment. Mailboxes are small on Starter at 5 GB, and the introductory price rises about fourfold at renewal. Help pages cover IMAP, POP3, authenticator-app sign-in and SPF, DKIM and DMARC setup, but they describe no single sign-on or security keys.

Best for: Small teams that want a low price per mailbox and can commit for years. Prices, facts and sources

9. Migadu

Migadu suits people who want many domains and addresses for a flat price and who use standard mail apps. The Mini plan is $7.50 a month for five mailboxes sharing 30 GB. The catches are no mailbox 2FA, no SLA in the default offer, email and ticket support only and a pooled 30 GB allowance.

Best for: Technical users who run many addresses and domains and use their own mail apps. Prices, facts and sources

Head to head

We read each vendor's own pages, record every fact with its source and date, and score it by the rules on how we score email hosting services. A tie goes to the lower price. Paid or free mailbox hosting on your own domain, for teams of 1 to 50, used in a web browser on Windows or any mail app. All numbers refer to a team of 5 mailboxes on the cheapest paid plan with a custom domain and at least 5 GB per mailbox (a pooled allowance is divided by 5). Encrypted-mail services, desktop mail apps and forwarding-only services are left out. Vendor claims about speed or quality are shown on product pages but never scored. Prices are in US dollars before tax.
