If you are considering Proton Mail for a company, small business, or professional email setup, one of the first things you will want to understand is Proton Mail Business pricing.
Proton for Business currently offers three main plans:
- Mail Essentials
- Workspace Standard
- Workspace Premium
For larger organizations, Proton also offers a custom-priced Enterprise plan.
In simple terms, Mail Essentials is best if your main priority is secure custom-domain email, while Workspace Standard is the better fit if you want a broader business workspace similar to Google Workspace or Microsoft 365.
Below, we’ll look at the pricing and features available as of October 2026.
Proton Mail Business Pricing
Proton Mail Business is generally priced per user.
You can choose between annual and monthly billing, with annual billing offering a lower effective monthly price.
| Plan | Annual Billing | Monthly Billing | Annual Cost with Annual Billing |
|---|---|---|---|
| Mail Essentials | $6.99 / user / month | $7.99 / user / month | $83.88 |
| Workspace Standard | $12.99 / user / month | $14.99 / user / month | $155.88 |
| Workspace Premium | $19.99 / user / month | $24.99 / user / month | $239.88 |
| Enterprise | Contact sales | Contact sales | Custom |
With annual billing, Mail Essentials and Workspace Standard are roughly 13% cheaper than monthly billing, while Workspace Premium is about 20% cheaper.
It is also important to understand how the advertised annual price works.
For example, the $6.99/month price for Mail Essentials under annual billing does not mean Proton charges $6.99 every month.
Instead:
$6.99 × 12 months = $83.88
and the annual amount is billed for the 12-month term.
Taxes may also apply depending on your billing location.
Mail Essentials — From $6.99
The most affordable business plan is Mail Essentials.
Pricing
- Annual billing: $6.99 / user / month
- Monthly billing: $7.99 / user / month
- Annual cost with annual billing: $83.88 / user / year
As the name suggests, this plan is primarily designed for businesses that want to use Proton Mail and Proton Calendar.
Main features include:
- 15 GB storage per user
- 10 email addresses per user
- Up to 3 custom email domains
- Custom-domain email
- Unlimited folders, labels, and filters
- Password-protected emails
- Catch-all email
- Automatic forwarding
- SMTP access for external services
- Support for Outlook, Thunderbird, and Apple Mail
- Proton Calendar
- Up to 25 calendars per user
- 1 booking page
- Proton Drive
- Docs and Sheets
- Proton Pass
- 1 VPN connection per user
- Proton Meet
- Limited access to Lumo AI
Despite the name “Mail Essentials,” the plan now includes basic access to several other Proton services, including Drive, Docs, Sheets, Pass, Meet, and VPN.
The main limitation is storage.
At 15 GB per user, Mail Essentials is suitable for email and light file storage, but it may be too limited if you want to use Proton Drive as your primary cloud storage platform.
Who Is Mail Essentials Best For?
Mail Essentials is a good fit if you:
- Want secure custom-domain email
- Do not need the full feature set of a larger business suite
- Already use another cloud storage platform such as Dropbox or Google Drive
- Run a small team or solo business
- Prioritize email privacy
If email is your main reason for using Proton, Mail Essentials is one of the easiest Proton Business plans to adopt at $6.99 per user per month with annual billing.
Workspace Standard — From $12.99
For teams that want to use Proton more broadly across their business, Workspace Standard is arguably the most balanced option.
Pricing
- Annual billing: $12.99 / user / month
- Monthly billing: $14.99 / user / month
- Annual cost with annual billing: $155.88 / user / year
Workspace Standard includes everything in Mail Essentials plus a much more complete set of Proton’s business tools.
Main Differences
- 1 TB storage per user
- 20 email addresses per user
- Up to 15 custom domains
- Custom workspace branding
- Email groups
- Proton Sentinel
- Up to 25 booking pages
- Up to 10 VPN connections per user
- VPN servers in 140 countries
- Team features in Proton Pass
- Proton Meet for up to 100 participants
- Meetings up to 24 hours
- Meeting recording
- Up to 2 simultaneous meetings
- Unlimited meetings per day
The biggest upgrade is storage, which jumps from 15 GB to 1 TB per user.
Because Proton Drive, Docs, and Sheets are also included, Workspace Standard can bring together:
- Calendar
- Cloud storage
- Documents
- Spreadsheets
- VPN
- Password management
- Video meetings
This means Workspace Standard is no longer just a higher-tier email plan.
It is much closer to a complete business workspace, similar in concept to Google Workspace or Microsoft 365.
Who Is Workspace Standard Best For?
Workspace Standard is a good fit if you:
- Want to use Proton across the company
- Are considering moving away from Google Workspace
- Want to move cloud storage to Proton Drive
- Want VPN and password management included in the same subscription
- Need centralized Proton management for multiple users
- Prioritize security across multiple workplace tools
Workspace Premium — From $19.99
The highest publicly listed plan is Workspace Premium.
Pricing
- Annual billing: $19.99 / user / month
- Monthly billing: $24.99 / user / month
- Annual cost with annual billing: $239.88 / user / year
Workspace Premium includes everything in Workspace Standard plus:
- 3 TB storage per user
- Up to 20 custom email domains
- Proton Meet for up to 250 participants
- Proton Scribe email writing assistant
- Lumo AI
- Access to more advanced Lumo models
- Unlimited Lumo prompts
- Expanded AI chat history
- Data retention policies
The biggest differences are AI features and advanced data management.
Mail Essentials and Workspace Standard include limited access to Lumo, while Premium unlocks a more complete AI experience.
Proton Scribe is also included with Premium.
On Mail Essentials and Workspace Standard, Scribe is generally offered as an optional add-on with a trial rather than being included by default.
Who Is Workspace Premium Best For?
Workspace Premium is a good fit if you:
- Want to use AI extensively in day-to-day work
- Need significantly more storage
- Run larger online meetings
- Need data retention policies
- Have stricter security or compliance requirements
For many small businesses, Workspace Standard will be sufficient.
Premium is aimed more at organizations that place greater emphasis on security, AI, storage, and data governance.
Enterprise — For Larger Organizations
Above the public plans is Enterprise.
Pricing is not publicly listed and requires contacting Proton.
Enterprise can include:
- Access to Proton services
- Customized plan configurations
- Dedicated account management
- Custom storage and other negotiated requirements
This plan is intended for larger organizations or businesses with specific security, compliance, or deployment requirements.
Annual Billing vs Monthly Billing
If you expect to use Proton Business long term, annual billing is more cost-effective.
Here is the cost for one user over one year.
| Plan | 12 Months of Monthly Billing | Annual Billing | Annual Savings |
|---|---|---|---|
| Mail Essentials | $95.88 | $83.88 | $12 |
| Workspace Standard | $179.88 | $155.88 | $24 |
| Workspace Premium | $299.88 | $239.88 | $60 |
Workspace Premium has the largest difference at $60 per user per year.
The savings become more significant as the number of users increases.
For example, with 10 users on Workspace Premium:
Monthly billing
$24.99 × 10 users × 12 months
= $2,998.80 / year
Annual billing
$19.99 × 10 users × 12 months
= $2,398.80 / year
That is a difference of $600 per year.
How Much Does Proton Business Cost for 5 or 10 Users?
Because Proton Business uses per-user pricing, total cost increases with the size of the team.
With annual billing:
| Team Size | Mail Essentials | Workspace Standard | Workspace Premium |
|---|---|---|---|
| 1 user | $83.88 / year | $155.88 / year | $239.88 / year |
| 5 users | $419.40 / year | $779.40 / year | $1,199.40 / year |
| 10 users | $838.80 / year | $1,558.80 / year | $2,398.80 / year |
For a 10-person company, Workspace Standard costs $1,558.80 per year with annual billing.
However, Workspace Standard also includes VPN, cloud storage, password management, and video meetings, so it is not directly comparable with the cost of a basic email hosting service.
What If You Pay in a Currency Other Than U.S. Dollars?
Proton Business pricing is listed in U.S. dollars.
If your card or bank account uses another currency, the final amount you pay can vary depending on:
- The exchange rate at the time of payment
- Foreign transaction or currency conversion fees charged by your card provider
- Applicable taxes
For that reason, the effective local-currency cost may change over time even if Proton’s U.S. dollar price remains the same.
If exchange-rate fluctuations matter to your budget, it is worth checking the final amount shown at checkout before committing to annual billing.
How Does Proton Business Pricing Compare with Google Workspace?
Many businesses considering Proton Mail Business will naturally compare it with Google Workspace.
As of October 2026, Google Workspace Business Starter is listed at $7 per user per month with an annual commitment.
Mail Essentials is $6.99 per user per month with annual billing.
So at the entry level, there is almost no price difference.
However, the products emphasize different things.
Google Workspace focuses on tools such as:
- Gmail
- Google Drive
- Docs
- Sheets
- Meet
- Gemini
Its main strength is collaboration and integration across Google’s ecosystem.
Proton focuses on:
- End-to-end encryption
- Zero-access encryption
- Proton Mail
- Proton Calendar
- Proton Drive
- Proton VPN
- Proton Pass
Its ecosystem is designed around privacy and security.
The decision is therefore not simply about which service is cheaper.
It is more useful to ask whether your organization values Google’s collaboration ecosystem or Proton’s privacy-first architecture more highly.
What Happened to Mail Professional and Business Suite?
When researching Proton pricing, you may still find older plan names such as:
- Mail Professional
- Proton Business Suite
However, Proton’s business plans have since been reorganized.
Mail Professional is now deprecated.
In 2026, Proton expanded its business product lineup under the Proton Workspace name.
The current structure is easier to think of as:
- Mail Essentials
- Workspace Standard
- Workspace Premium
- Enterprise
Because older articles may still show legacy names and outdated pricing, always check the latest official Proton pricing before subscribing.
Proton Mail Business Includes a 14-Day Free Trial
Proton for Business offers a 14-day free trial.
During the trial, you can test the premium features included with the plan you select.
The trial supports:
- Up to 10 users
- Up to 10 devices
- Premium features from the selected plan
This means you can test not only Mail Essentials, but also Workspace Standard or Workspace Premium before deciding whether they fit your workflow.
A Payment Method Is Required for the Free Trial
One important detail is that a payment method is required when starting the free trial.
After the 14-day trial ends, the subscription automatically converts to a paid plan and Proton charges the selected plan price.
If you do not want to continue, cancel before the free trial ends.
The free trial is generally intended for new Proton for Business customers who have not previously used a paid business subscription or free business trial.
Also note that changing to another business plan during the trial may not be supported.
There Is Also a 30-Day Money-Back Guarantee
Even after the 14-day free trial ends and the account moves to a paid subscription, Proton offers a 30-day money-back guarantee.
This gives businesses a practical evaluation process:
- Test Proton Business free for 14 days
- Move to the paid plan if everything looks suitable
- Continue evaluating the service in real-world use during the refund period
Because migrating business email should be handled carefully, it is usually better to test Proton with a small number of users before moving every mailbox at once.
