Top 5 Small Business Email Hosts in 2026

Choose an email host for your small business by comparing mailbox capacity, backup and support. This 2026 ranking also highlights storage, migration tools and limits that matter as your team grows.

How we ranked these email hosts

We prioritised mailbox capacity, backup and recovery, and support access because small teams need enough accounts and a practical way to restore messages or get help. We also considered storage, migration tools and domain support, which affect how easily you can move staff across and set up business addresses. Two-step verification, SPF, DKIM and DMARC, and admin controls add useful safeguards. We rank on listed specs and features rather than lab tests.

1. Cloud86 E-mail hosting Start

Cloud86 is our first pick for a small business that wants a compact team package with backup and readily available help. It lists 10 mailboxes, 5 GB of storage per user and support for two custom domains. Backup and recovery are included, and support is available by live chat and phone, with 24/7 availability listed.

The plan also includes webmail, IMAP, POP3 and SMTP, a spam and virus filter, two-step verification, and SPF, DKIM and DMARC. Cloud86 lists a Dutch data location and a 30-day money-back guarantee. There is no import tool, so plan how to move existing mail. Storage is also lower than on several providers below.

• Strengths: 10 mailboxes, two domains, backup, 24/7 phone and live-chat support, and email authentication features.
• Limits: 5 GB per user and no migration import tool.

Pick Cloud86 if your team fits within 10 accounts and backup plus round-the-clock support matter more than an automated migration.

2. Greatmail Standard Edition

Greatmail suits a five-person team moving existing email into a managed setup. It lists five mailboxes and 10 GB per user, plus a migration tool and admin panel. Backup and recovery, webmail, spam and virus filtering, and SPF, DKIM and DMARC are included. Phone and email support are available, and billing can be monthly.

The plan has a five-user minimum, so it will not suit a smaller team that wants fewer accounts. Greatmail lists its data location as the United States and TLS encryption in transit. It does not list calendar and contact tools or Exchange/ActiveSync. Attachments are limited to 50 MB.

• Strengths: 10 GB per user, backup, migration tool, admin panel, phone and email support.
• Limits: Five-user minimum, US data location, and no listed calendar, contacts or Exchange/ActiveSync.

Choose Greatmail if you have five users to move and value a migration tool with backup over bundled calendar features.

3. STRATO Mail Basic

STRATO stands out for a small company that needs many addresses. It lists 25 mailboxes, 250 aliases and one custom domain. Aliases can provide role-based addresses, such as enquiries, without a separate mailbox for each one. A migration tool is included, with support by phone and email.

Each user gets 2 GB of storage, the lowest allowance among these five providers, and backup or recovery is not listed. That is a trade-off if staff keep large attachments or need a safety net for deleted messages. STRATO also includes webmail, IMAP/POP3/SMTP, filters, a catch-all address, an autoresponder, and calendar and contact features. Attachments can be up to 75 MB. Cloud file storage, office software and Exchange/ActiveSync are not listed.

• Strengths: 25 mailboxes, 250 aliases, migration tool, phone and email support, and 75 MB attachments.
• Limits: 2 GB per user, no listed backup or recovery, and one custom domain.

Consider STRATO if mailbox and alias counts matter most and your team can work within the smaller storage allowance.

4. Mailfence Entry

Mailfence suits a small team looking for email alongside collaboration tools and account controls. It supports up to five users, with 10 GB per user, two custom domains and an admin panel. The plan includes end-to-end encryption, two-step verification, SPF, DKIM and DMARC, and a Belgian data location. It also bundles cloud file storage, office software, calendar and contacts, mobile apps, and Exchange/ActiveSync.

A migration tool can help when moving accounts, and attachments can be up to 50 MB. The daily sending limit is 500 emails. Email is the only listed support channel, and billing is annual. Mailfence lists no money-back guarantee for this plan. Its five-user cap also leaves less room for growth than higher-ranked options.

• Strengths: 10 GB per user, end-to-end encryption, migration, office tools, mobile apps and Exchange/ActiveSync.
• Limits: Five-user maximum, email-only support, annual billing and a 500-email daily sending limit.

Choose Mailfence if integrated email and office tools, encryption and Exchange/ActiveSync matter more than phone support or room for a larger team.

5. Infomaniak Mail Service

Infomaniak offers the largest listed capacity in this ranking: up to 1,000 mailboxes and users, with unlimited storage per user. The service includes backup and recovery, a migration tool, an admin panel, two-step verification, SSO, mobile apps, and SPF, DKIM and DMARC. Support is available by live chat, phone and email.

It also lists a 200 MB attachment limit, calendar and contacts, video conferencing, and a Swiss data location. Its uptime guarantee is listed as 99.99%; this is a provider-listed commitment, not a measurement from our tests. Support is not listed as 24/7, and the daily sending limit is 500 emails. Cloud file storage is not included. Its capacity may exceed a very small team’s needs, but backup and several support channels are useful inclusions.

• Strengths: Up to 1,000 mailboxes, unlimited storage, backup, migration, SSO, and phone, chat and email support.
• Limits: Support is not listed as 24/7, sending is limited to 500 emails per day, and cloud file storage is not included.

Pick Infomaniak if you want extensive mailbox capacity and several support channels, and do not require round-the-clock support.

Why name.eu E-Mail Tree missed the list

name.eu lists 20 mailboxes, unlimited aliases and Exchange/ActiveSync, but only 0.5 GB per user. It may suit a team with light storage needs, but we prioritised more room for everyday business email.

How to choose email hosting for your team

Count the people who need separate sign-ins, then decide whether shared addresses should be aliases or separate accounts. A team may need personal inboxes plus role addresses such as sales or support, but not every address needs its own mailbox. Check mailbox and alias limits against your current needs and likely hiring plans.

Estimate how much mail and how many attachments each person will keep. Storage ranges from 2 GB per user with STRATO to unlimited with Infomaniak. If losing messages would disrupt work, look for backup and recovery. When switching providers, check for a migration tool and confirm it covers the accounts you need to move.

Match support to your working hours. Cloud86 lists 24/7 support by phone and live chat; Infomaniak offers several contact channels but does not list 24/7 availability. Check security features, data location, and sending or attachment limits too. For a small business choosing in 2026, these practical details can matter more than mailbox count alone.
