Collaboration enables customers to set up encrypted email with custom domain names through streamlined integration.

Porkbun and Proton Mail have formed a partnership to provide secure email hosting with custom domain names.
The integration allows users to set up professional email addresses through an automated API connection.
Proton Mail offers end-to-end encryption for emails, including subject lines, content, and attachments.
Pricing for Porkbun customers starts at $5.99 per month for Proton Mail Essentials or Professional plans.
The service includes access to Proton’s broader security suite including Calendar, Drive, Pass, and VPN.

Porkbun and Proton Mail announced a new partnership on March 12, 2025, combining domain registration with encrypted email services. The collaboration aims to simplify the process of establishing secure, professional email addresses using custom domains while eliminating technical setup barriers.

The partnership addresses growing concerns about email privacy and security while helping businesses and individuals establish more credible online identities. Through an API integration, Porkbun domain owners can now configure Proton Mail hosting directly from their domain management dashboard without manual DNS configuration or technical expertise.

Email encryption has evolved significantly since PGP (Pretty Good Privacy) was introduced in 1991. While early encryption methods required technical knowledge and manual key management, modern services like Proton Mail have made security features more accessible to everyday users.

End-to-end encryption, a technique where messages are encrypted on the sender’s device and only decrypted on the recipient’s device, prevents intermediaries from accessing message content.

Proton Mail implements this security approach across the entire email, including subject lines and attachments—areas often left unprotected by standard email providers. This comprehensive protection appeals particularly to privacy-conscious users and those handling sensitive information.

Beyond email hosting, the partnership gives Porkbun customers access to Proton’s complete security suite. This ecosystem includes Proton Calendar for private scheduling, Proton Drive for secure file storage, Proton Pass for password management, and Proton VPN for protected internet browsing.

The subscription model starts at $5.99 monthly for Proton Mail Essentials or Professional plans when purchased through Porkbun.

Setting up the service requires just a few steps through the Porkbun domain management interface.

Users select their domain, click the email icon, choose Proton Mail, and follow the guided setup process. The companies have emphasized the simplicity of the process, stating that the API handles all technical configuration automatically.

The collaboration targets several user groups including small business owners seeking professional communications, freelancers wanting to enhance their online presence, privacy advocates concerned about data security, and nonprofit organizations protecting sensitive communications.

This partnership represents a growing trend in the domain and hosting industry toward offering integrated security services rather than treating them as separate products. Industry analysts note that bundling these services helps users implement better security practices without increasing technical complexity.
