That bundle only saves money if it replaces tools you would otherwise pay for.

Use privacy-focused email with encrypted mailbox storage and business-domain options. Proton combines mail and calendar with broader workspace bundles for teams that also need storage and other services. Encryption does not remove the need to manage recipients, sharing, and account recovery. Custom-domain business use requires a suitable paid plan. Proton's business email plans combine encrypted mail with different workspace bundles. Mail Essentials is the narrower email choice; larger workspace plans add services such as more storage, VPN and password management. That bundle only saves money if it replaces tools you would otherwise pay for.
