Why use Proton Mail for team collaboration?
Email is the backbone of business communication, both internally and externally. Strong communication drives customer satisfaction, morale, and efficiency, while poor teamwork carries a high cost. This makes your email the most vital team collaboration tool. Here’s how Proton Mail helps set up your business for success:
Collaborate with peace of mind
Enable your workforce to communicate freely and securely, even outside of the organization. Proton Mail’s powerful end-to-end encryption and zero-access architecture ensure your business data is always protected.
Streamline group communication
Create email groups for different teams and purposes, and instantly contact all members of a group through its dedicated email address.
Boost efficiency with automation
Enjoy granular control over your inbox by configuring automation rules and filters, including setting vacation responders, blocking spam, and sorting messages into specific folders for easy access.
Stay in sync with Proton Calendar
Included with Proton Mail, Proton Calendar lets you view your colleagues’ availability, set up meetings and virtual calls effortlessly, and subscribe to external calendars to track important events and public holidays.
Use across devices and email clients
Keep your team connected seamlessly no matter which device or email client they’re on. Proton Mail has native apps for web, mobile, and desktop, and works with various IMAP/SMTP email clients such as Apple Mail, Outlook, and Thunderbird.
Easily migrate your team to Proton Mail
