Proton Mail Setup Checklist for 2026

Use this checklist before you move your main inbox. It keeps the setup practical and prevents the two mistakes that cause the most trouble: losing email during a domain migration and assuming every outside recipient will get automatic end-to-end encryption.

Why Set Up Proton Mail

Proton Mail offers end-to-end encryption by default. Emails sent between Proton Mail users are encrypted automatically. The service uses zero-knowledge architecture, meaning Proton cannot read your emails or access your encryption keys.

Swiss privacy laws are one reason many privacy-focused users choose Proton Mail. The service includes open-source apps, encryption-first account design, and independent security reviews.

Proton Mail provides a free tier for testing private email. Paid Mail and Business plans add more addresses, storage, custom domains, Bridge support, and team features. Check current plan details through Proton Mail before moving a business domain.

9. Configure domain settings

Custom domains allow you to use your own domain name with Proton Mail. Use a paid plan for custom domains, then configure DNS records to route email through Proton Mail servers.

Need a custom domain? Compare Proton Mail plans → to use your own domain name while keeping the Proton Mail privacy model.

Configure DNS Records

1. Create every needed mailbox and alias in Proton Mail first.
2. Log in to your domain registrar or DNS provider.
3. Add the MX records shown inside Proton Mail’s domain settings and remove conflicting old MX records.

6. Add a DMARC record so receivers know how to treat spoofed mail.
7. Verify the records inside Proton Mail and wait for DNS propagation.

DNS records tell other email servers how to route emails for your domain. MX records point mail to Proton Mail. SPF, DKIM, and DMARC records help verify email authenticity and reduce spoofing. If your team needs a broader decision path before moving DNS, compare secure email for business and Proton Mail alternatives.

Create Email Addresses

1. In Domain Names settings, click your domain
2. Click “Add New Address”
3. Enter your desired email address
