Why Migrate from Gmail to ProtonMail?
Pre-Migration Audit
Step-by-Step Migration
- •Step 1: Open a ProtonMail account, Sign up at proton.me with no phone number required for the free tier (you may be asked for a one-time email or captcha verification on signups from suspicious networks). Choose a username carefully, it becomes your address @proton.me.
- •Step 2: Add your custom domain, Optional but recommended for long-term identity. ProtonMail supports custom domains on the paid Mail Plus plan ($3.99/mo) and bundled in Proton Unlimited. Add MX records, SPF, DKIM, DMARC per the in-app instructions, propagation takes 1-24 hours.
- •Step 3: Import historical Gmail, Use the in-app Easy Switch tool to import Gmail messages, contacts, and calendars. Easy Switch uses OAuth: Google asks you to authorize Proton to read your mail. Imports run server-side over days for large mailboxes; you receive a completion email.
- •Step 4: Set up forwarding from Gmail, In Gmail Settings → Forwarding and POP/IMAP, forward all incoming mail to your Proton address. Keep this active for 90-180 days to catch services you forgot to update. After confidence period, you can stop forwarding and delete the Gmail account or leave it as a dormant placeholder.
- •Step 5: Update accounts that mail you, Bank, utilities, social, work-adjacent services, change the email of record to your Proton address one at a time. Most systems require email verification, so plan this in batches. Use a password manager search to find every account tied to your Gmail.
- •Step 6: Configure mobile and desktop clients, ProtonMail mobile apps work over end-to-end encryption out of the box. For desktop IMAP/SMTP access (Apple Mail, Thunderbird), install Proton Mail Bridge, it runs locally and provides standard IMAP/SMTP endpoints that decrypt messages on your machine.
- •Step 7: Decommission Gmail safely, Once you are 90 days clean (no important mail still arriving at Gmail), download a Google Takeout archive for backup, then delete the account. Or leave Gmail as a forwarder if you prefer the safety net, there is no requirement to fully sever.

Frequently Asked Questions
How long does migration from Gmail to ProtonMail take?
Most users complete the active migration in 3-6 hours of focused weekend work. The "tail" of catching stragglers (services you forgot to update, contacts who keep using the old channel) typically lasts 2-4 weeks. After 30 days clean, you can decommission Gmail.
Will I lose access to my Gmail data during the migration?
No. The migration runs in parallel, you keep Gmail fully active until you have verified ProtonMail works for you. The 7-step migration in this article never requires deleting Gmail until you are ready.
What if a service I depend on only supports Gmail?
Maintain a minimal Gmail account for that specific service. Most users find that 90% of their use cases switch cleanly, with 10% requiring continued Gmail for vendor-specific reasons. The 10% is acceptable, perfection is not the goal; meaningful privacy improvement is.
Can I roll back if ProtonMail does not work for me?
Yes. The migration steps are reversible. If ProtonMail does not meet your needs in the 30-day evaluation window, you can resume using Gmail with no permanent loss. Most users do not roll back, but having the option reduces the anxiety that often blocks switching.
How do I make sure I do not regress?
Three habits: (1) Avoid creating new accounts on Gmail or its sister products. (2) Subscribe to ProtonMail's release notes to track feature parity. (3) Run periodic audits with NexusBro to catch creeping Gmail dependencies, a 30-second audit catches most regressions before they compound.
