Top 5 Google Workspace Alternatives in 2026

Choosing a Google Workspace alternative means deciding whether you need a full bundle of office software, storage and meetings, or mainly business email with administration tools. Our 2026 ranking separates those options so you can focus on the fit for your team.

How we ranked these alternatives

We put bundled suites first because they match more of the services people may want to replace: email, office software, cloud storage, video meetings, calendars and contacts. Proton Mail Essentials and mailbox.org Standard list all of those. We then considered mail-first plans with controls such as SSO, an admin panel and two-step verification. Storage, user limits, domain support, migration tools and security features help distinguish plans within each group. We rank on listed specs and features rather than lab tests.

1. Proton Mail Essentials

Proton Mail Essentials is the strongest match if you want to replace several parts of Google Workspace together rather than move email alone. Proton lists office software, cloud storage, video meetings, calendar and contacts, alongside business email and an admin panel. It also lists end-to-end and zero-access encryption, making it a notable choice for teams that prioritise privacy.

Each user gets 15 GB of storage, and the plan supports three custom domains, 10 aliases and catch-all email. IMAP, POP3 and SMTP are supported, and Proton lists an import tool for migration. Swiss data location, two-step verification and spam and virus filtering add further security and administration options. Exchange/ActiveSync is not included, so check compatibility if your setup depends on it.

• Strengths: Office software, cloud storage, video meetings, calendar and contacts, an admin panel and mobile apps.
• Strengths: End-to-end and zero-access encryption, three custom domains, 10 aliases and a free trial.

• Limits: Storage is 15 GB per user, with one mailbox per user.
• Limits: Exchange/ActiveSync is not listed.

Choose Proton if you want a privacy-oriented bundle and need more than email. It also suits a small team that needs custom domains and migration support without giving up calendars or video meetings.

2. mailbox.org Standard

mailbox.org Standard is another full-suite option, listing office software, cloud storage, video meetings, calendar and contacts. Its 20 GB per-user storage allocation is higher than Proton Mail Essentials’ 15 GB, and its German data location may suit organisations that prefer that location. The plan also includes backup and recovery.

It supports IMAP, POP3 and SMTP, catch-all addresses and up to 50 aliases. Migration import, mobile apps and two-step verification are listed. Encryption covers data in transit with TLS and data at rest. The plan has no listed free option; support is by email, and 24/7 support is not listed.

• Strengths: Office software, cloud storage, meetings, calendar and contacts in one plan.
• Strengths: 20 GB per user, 50 aliases, backup and recovery, and German data location.

• Limits: No free plan is listed.
• Limits: Support is by email, with no 24/7 support listed.

Pick mailbox.org if you want a broad bundle with more listed storage per user than Proton and value backup and recovery. It is less suitable if you need a free plan or round-the-clock support.

3. Zoho Mail Lite

Zoho Mail Lite is a mail-first choice for teams that want SSO and administration features without requiring office software or file storage in the same plan. Zoho lists SSO, an admin panel, video meetings, calendar and contacts, plus Exchange/ActiveSync. That makes it useful when sign-in management and mail-client compatibility matter more than an all-in-one bundle.

The plan includes 5 GB per user, one mailbox per user, IMAP, POP3 and SMTP, and a migration import tool. It supports two-step verification, desktop and mobile apps, and TLS encryption in transit. Zoho lists a 99.99% uptime guarantee and 24/7 support by live chat, phone and email. Billing is annual; there is no free trial, and cloud storage and office software are not included.

• Strengths: SSO, an admin panel, Exchange/ActiveSync, meetings, calendar and contacts.
• Strengths: Desktop and mobile apps, migration import, and 24/7 support across several channels.

• Limits: Storage is 5 GB per user, with no cloud storage or office software listed.
• Limits: Annual billing is listed, and there is no free trial.

Choose Zoho Mail Lite if you need managed email with SSO, ActiveSync and responsive support, but will source office software and file storage separately. It is also the clearest option here if a listed uptime guarantee matters to your selection.

4. Infomaniak Mail Service

Infomaniak Mail Service suits organisations that want email administration and large mailbox capacity rather than a bundled office and storage suite. It lists SSO, an admin panel, calendar and contacts, video meetings, mobile apps and two-step verification. Its Swiss data location and 99.99% uptime guarantee are further points to consider.

The plan lists unlimited storage per user, support for up to 1,000 mailboxes and up to 1,000 users. IMAP, POP3 and SMTP, migration import, filters and rules, autoresponders, and SPF/DKIM/DMARC are included. The sending limit is 500 emails per day, and the maximum attachment size is 200 MB. Cloud storage is not included, so mailbox storage is not a substitute for a bundled file-storage service.

• Strengths: Unlimited listed mailbox storage, SSO, an admin panel and support for up to 1,000 users.
• Strengths: 200 MB maximum attachments, migration import, Swiss data location and a 99.99% uptime guarantee.

• Limits: Cloud storage is not listed.
• Limits: Sending is limited to 500 emails per day, and 24/7 support is not listed.

Consider Infomaniak when mailbox capacity and central administration matter more than office apps or file storage. Check that the daily sending limit fits your team’s needs before moving.

5. Mailfence Entry

Mailfence Entry sits between a mail-first service and a compact suite. It lists office software, cloud storage, calendar and contacts, an admin panel and Exchange/ActiveSync, but not video meetings. End-to-end encryption, two-step verification and a Belgian data location make it a distinctive option for teams that value those features.

Each user gets 10 GB of storage, with 50 aliases, catch-all support and up to two custom domains. Mailfence supports IMAP, POP3 and SMTP, migration import and mobile apps. It supports up to five users and limits sending to 500 emails per day. Billing is annual, and no money-back guarantee is listed, so check the user limit and billing terms before committing.

• Strengths: Office software, cloud storage, calendar and contacts, an admin panel and Exchange/ActiveSync.
• Strengths: End-to-end encryption, 50 aliases, two custom domains and Belgian data location.

• Limits: Video meetings are not listed.
• Limits: The plan supports up to five users and has a 500-email daily sending limit.

Choose Mailfence if you want a smaller bundled setup with end-to-end encryption and ActiveSync, and do not need built-in video meetings. Its five-user ceiling makes it a poor match for a larger organisation.

Why Microsoft Exchange Online did not make the list

Microsoft Exchange Online (Plan 1) lists SSO, 50 GB per user, an admin panel, backup and recovery, and calendar and contacts. It did not make this ranking because it does not list office software, cloud storage or video meetings, leaving it short of the bundled-suite brief and without the full feature mix of the selected mail-first plans.

How to choose an alternative in 2026

Start by listing which Google Workspace services your team uses. If you rely on office software, shared file storage, video meetings and calendars as well as email, begin with Proton Mail Essentials or mailbox.org Standard. Both list those suite features. Compare storage per user, data location, encryption and support to decide which bundle fits your requirements.

If you already have separate office and file-storage tools, a mail-first option may fit better. Zoho Mail Lite offers SSO, an admin panel and Exchange/ActiveSync; Infomaniak emphasises mailbox capacity and administration. Mailfence adds office software and cloud storage but has no listed video meetings and supports at most five users.

Before migrating, check how many users and custom domains you need, whether your mail clients require Exchange/ActiveSync, and how much storage each person uses. Confirm that your sending volume fits any daily cap, and decide whether monthly billing, migration tools, backup or a particular data location is essential. In 2026, a checklist like this will help you choose a replacement based on your actual workflow, not email alone.
