Top 5 Email Hosting with Calendars in 2026

Use this 2026 ranking to compare email services that include calendars and contacts, with priority given to plans that also bundle office software and video meetings. You can see which option fits your team’s storage, security and administration needs.

How we ranked these email services

Calendar and contact features are the starting point: every service here lists both. We then favoured plans that pair them with office software and video meetings, since those bundles let you handle email, scheduling, documents and calls within a broader work setup. Storage, security controls, data location, mailbox capacity and practical limits also matter. We rank on listed specs and features rather than lab tests, so check that a plan’s specific tools fit your team’s workflow before you choose.

1. Google Workspace Business Starter

Google Workspace Business Starter is the strongest all-round pick here if you want email, calendar, contacts, office software and video meetings in one plan. It lists 30 GB of storage per user, and supports up to 300 users, so it can work for a growing team as well as a solo account. SSO and two-step verification give administrators useful account controls.

For day-to-day email management, the plan includes webmail, IMAP/POP3/SMTP, filters and rules, aliases, catch-all, spam and virus filtering, and an import tool. Google lists TLS in transit and encryption at rest, plus SPF, DKIM and DMARC support. You can choose monthly or annual billing, and there is a free trial. Each user gets one mailbox, with a listed sending limit of 2,000 emails per day and a 25 MB maximum attachment size.

• Strengths: Calendar and contacts, office software and video meetings are bundled; 30 GB per user; SSO, 2FA and migration import are listed.
• Limits: Storage is lower than some specialist mailbox plans, and the 25 MB attachment limit may constrain large-file email. The plan does not list backup and recovery.

Choose it if your priority is a broadly equipped workplace plan rather than email alone, especially if you want common scheduling, document and meeting tools together. Its large maximum user count also makes it a sensible fit for organisations that may add accounts over time.

2. mailbox.org Standard

mailbox.org Standard is a good fit if you want calendar and contacts with office software, cloud storage and video meetings, while keeping a listed German data location. The plan includes 20 GB per user, webmail and mobile apps, and supports standard IMAP/POP3/SMTP access. It also offers aliases, catch-all and a migration import tool for moving existing mail.

For privacy and account protection, mailbox.org lists GDPR compliance, TLS in transit, encryption at rest and two-step verification. Backup and recovery are included, which is a useful distinction when you are planning for accidental loss or a migration. Billing can be monthly or annual, and a free trial is listed. Support is by email; it is not listed as available 24/7.

• Strengths: Calendar and contacts sit alongside office software, video meetings and cloud storage; 20 GB per user; German data location; backup and recovery.
• Limits: Support is email-based and not listed as 24/7. The plan lists one mailbox, and it does not specify a maximum attachment size or a daily sending limit.

Consider it if a Germany-based data location and recovery features matter alongside the bundled work tools. It offers less listed storage per user than the top-ranked plan, but combines email, documents, files and meetings in a compact package.

3. Proton Mail Essentials

Proton Mail Essentials stands out for users who want calendar and contacts with office software and video meetings, while placing strong emphasis on encryption. Proton lists end-to-end and zero-access encryption, plus a Swiss data location, two-step verification and open-source status. Those features make it the privacy-focused choice in this ranking, though you should check how its tools fit with your existing systems.

The plan includes 15 GB per user, cloud storage, an admin panel, webmail and mobile apps. It supports custom domains, with three listed, and offers filters, catch-all, aliases and an import tool. Standard IMAP/POP3/SMTP support is listed, but Exchange/ActiveSync is not. A free plan, free trial and 30-day money-back guarantee are also listed; the paid plan itself is billed per user, with monthly and annual options.

• Strengths: Calendar and contacts, office software, video meetings and cloud storage; end-to-end and zero-access encryption; Swiss data location and open-source status.
• Limits: No Exchange/ActiveSync support is listed. Storage is 15 GB per user, and the maximum attachment size is 25 MB.

Pick Proton if the encryption model and Swiss data location carry more weight for you than compatibility with Exchange/ActiveSync. It still provides a broad set of workplace tools, but teams that depend on ActiveSync should look elsewhere in this ranking.

4. Infomaniak Mail Service

Infomaniak Mail Service pairs calendar and contacts with video meetings, SSO and an admin panel. It does not list office software or cloud storage, so it is less of a complete workplace bundle than the three services above it. Its standout capacity is unlimited storage per user, alongside support for up to 1,000 mailboxes and 1,000 users.

The plan includes webmail, mobile apps, filters and rules, an import tool, SPF/DKIM/DMARC support and two-step verification. Infomaniak lists a Swiss data location, backup and recovery, and a 99.99% uptime guarantee. Support is available by live chat, phone and email, though not 24/7. One operational limit to consider is the listed daily sending cap of 500 emails; the maximum attachment size is 200 MB.

• Strengths: Unlimited storage per user; calendar and contacts with video meetings; 1,000-mailbox capacity; 200 MB attachments; backup and recovery.
• Limits: Office software and cloud storage are not listed. The 500-email daily sending limit may not suit high-volume email workflows.

Choose Infomaniak if storage capacity and a large mailbox allowance are more important than having office software and cloud files bundled in. The large attachment allowance is also useful if people regularly need to send sizeable files by email.

5. Zoho Mail Lite

Zoho Mail Lite includes calendar and contacts, video meetings, Exchange/ActiveSync and SSO. It is the most stripped-back bundle in this top five: office software and cloud storage are not listed, and each user has 5 GB. Still, the combination of ActiveSync support and a desktop app may suit people who want to connect mail and scheduling with their established devices.

The plan provides webmail, mobile apps, an admin panel, a migration import tool, two-step verification and spam and virus filtering. Zoho lists TLS in transit, but does not list encryption at rest. Its support options include live chat, phone and email, with 24/7 availability listed. Billing is annual only, and there is no free trial. The maximum attachment size is 30 MB, and the plan lists a 99.99% uptime guarantee.

• Strengths: Calendar and contacts, video meetings, Exchange/ActiveSync and SSO; 24/7 support; desktop and mobile apps.
• Limits: 5 GB per user; no office software or cloud storage listed; annual billing only and no free trial; TLS in transit is the listed encryption protection.

Consider Zoho if ActiveSync, 24/7 support and a low storage requirement matter more than a full office suite or file storage. Its feature set is narrower than the higher-ranked options, so check whether 5 GB per user is enough for your mail and attachments.

Near misses

Microsoft Exchange Online (Plan 1) has calendar and contacts, 50 GB per user, SSO and a 150 MB attachment limit, but it does not list office software, cloud storage or video meetings. Mailfence Entry includes calendar and contacts, office software, cloud storage and end-to-end encryption, but does not list video meetings.

How to choose

Start by deciding whether you need a bundled workplace or mainly a mailbox with scheduling. If you want documents and meetings alongside calendar and contacts, compare Google Workspace, mailbox.org and Proton first. Then match storage to real use: Zoho lists 5 GB per user, while Infomaniak lists unlimited storage. Factor in attachment limits too, especially if your team emails large files.

For a business account, check the controls as carefully as the apps. SSO, two-step verification, encryption, migration tools and backup or recovery can affect setup and ongoing administration. If you rely on Exchange/ActiveSync, Zoho lists it, while Proton explicitly does not. Finally, verify daily sending limits, billing frequency, support hours and data location against your needs. In 2026, the best choice is the one whose bundled tools and practical limits match how your team actually works.
