Proton Mail Business Pricing India 2026 — Plans, Features & How to Get a Quote

If your business is considering Proton Mail for encrypted business email, understanding the plan structure — what each tier includes, how pricing works, and how to get an INR quote in India — is the first step.

Unlike standard SaaS products where pricing is published on the website, Proton Mail for Business is best purchased through an authorised partner for correct INR billing, GST invoice, and assisted setup. This guide covers everything you need to know before requesting a quote.

What Is Proton Mail for Business?

Proton Mail is not simply an "email provider with better privacy settings." It is architecturally different from Google Workspace and Microsoft 365 at the cryptographic level:

Zero-access encryption: Your email is encrypted on your device before it leaves, using keys only you hold. Proton's servers store only encrypted data. Even Proton cannot read your email — not for ads, not for compliance, not under any legal order under Swiss jurisdiction.

End-to-end encryption: Emails between Proton Mail users are automatically end-to-end encrypted. Emails to non-Proton users can be sent with password protection or standard SMTP (still encrypted in transit via TLS).

Open source and audited: Proton Mail's code is publicly available and regularly audited by independent security firms. The privacy claims are cryptographically verifiable — not a policy promise.

For businesses handling sensitive legal, financial, medical, or client communications, this is categorically more private than any mainstream email provider.

Proton Mail Business Plans — What Each Tier Includes

Mail Essentials

Mail Essentials is Proton's entry-level business plan. It provides all the core encrypted email functionality with a custom domain — the minimum viable configuration for a business.

What you get:

• Custom domain email (yourname@yourbusiness.com)
• 15 GB encrypted storage per user
• End-to-end encryption for all mail
• Proton Calendar (encrypted)
• Proton Contacts (encrypted)
• Admin console for user management
• Priority email support
• Up to 10 email addresses per user

Best for: Small businesses (2–25 users) that primarily need encrypted custom-domain email and are not yet using Proton Drive or Proton VPN.

Proton Business (Recommended)

Proton Business is the full productivity suite. In addition to encrypted email, it includes Proton Drive (encrypted cloud storage) and Proton VPN — creating a comprehensive privacy-first workspace.

What you get (everything in Essentials, plus):

• 500 GB encrypted storage per user (vs. 15 GB in Essentials)
• Proton Drive — encrypted cloud storage, shared drives, file versioning
• Proton VPN Business — encrypted internet access for all users
• Multiple custom domains on one account
• Advanced admin controls — user groups, login policies, audit logs
• Extended support

Why it matters for Indian businesses: The 500 GB per user is competitive with Google Workspace Business Standard. The inclusion of Proton VPN is a significant addition — for businesses with remote or travelling employees, Proton VPN provides encrypted internet access across public WiFi, hotel networks, and shared connections.

Enterprise

Proton Enterprise is for large organisations that need dedicated infrastructure, custom SLAs, and enterprise-grade identity management.

What you get (everything in Business, plus):

• Dedicated infrastructure (data isolated from other customers)
• Unlimited custom domains
• SSO / SAML 2.0 integration (connect to Azure AD, Okta, Google)
• Custom retention and archiving policies
• eDiscovery and compliance tooling
• Custom storage allocation
• Dedicated account manager and SLA

Best for: Enterprises with 100+ users, compliance-driven deployments, or organisations that need Proton integrated into an existing identity provider.

How Proton Mail Pricing Works

Proton Mail for Business is priced per user per month, billed annually. The exact INR price depends on:

1. Plan tier — Mail Essentials, Business, or Enterprise
2. Number of users — volume pricing applies for larger teams
3. Billing tenure — annual billing gives the best per-month rate
4. Exchange rate — Proton's list pricing is in EUR/USD; INR pricing is converted at time of quote

Because INR pricing fluctuates with exchange rates and Proton periodically adjusts plan pricing, we do not publish fixed INR figures here. The correct approach is to:

Request a quote from Cloudfy Systems — we provide an exact INR price with GST breakdown, locked at the time of purchase. You get a GST invoice for ITC claims and the certainty of a firm price.

What to Ask for When You Request a Quote

To get an accurate Proton Mail quote from Cloudfy, have the following ready:

Team size: How many users need Proton Mail? This is the primary pricing driver.

Plan preference:

• Mail Essentials (email + calendar + contacts, 15 GB)
• Proton Business (full suite + Drive + VPN, 500 GB)
• Enterprise (custom scale)

If you are unsure, share your use case and we will recommend the right plan.

Custom domain: Do you already own a domain? (e.g. yourbusiness.com) If yes, we will configure the MX records to point to Proton as part of setup. If not, we can advise on domain registration.

Current email provider: Are you migrating from Gmail, Google Workspace, Microsoft 365, Zoho Mail, or another provider? If yes, we will plan a migration to move your historical email, contacts, and calendar to Proton.

Tenure: Annual billing is standard. Multi-year (2 or 3 year) commitments may be available for Enterprise plans.

Proton Mail vs Alternatives — Value Comparison

Key insight: Proton Business is comparably priced to Google Workspace Business Starter or Microsoft 365 Business Basic — but adds end-to-end encryption, Swiss privacy protection, and Proton VPN that neither Google nor Microsoft offers.

Who Should Buy Which Plan

Mail Essentials is right if:

• You have a small team (2–15 users)
