ProtonMail Users: How Many People Use ProtonMail in 2023?


For those who are curious to know how many people use ProtonMail in 2023, the answer is over 70 million.

Such a number is already a 20 million increase from its 50 million user count in 2021. 

The platform’s global user count started its dramatic growth during the pandemic, at a time when companies migrated the majority of their operations to the web.

This is also the period when crypto users started to seek a highly-secured platform where they can trust their personal credentials with little to no fear of online attacks. 

Having been founded in 2013, the Switzerland-based ProtonMail did not reach its first 2 million users until 2017.

This came after the management decided to open its services to the public in 2016, from being an “invite-only” site for three years.

ProtonMail’s User Count Over the Years

As mentioned, ProtonMail only opened to the public in 2016.

Despite being considered a new market entrant in the end-to-end encryption email service, it already recorded a stellar performance so far.

Here is ProtonMail’s annual user count from 2017 to the present.

  • 2017 – after spending its first year accommodating new email accounts from the public, ProtonMail’s user count hit 2 million for the first time
  • 2018 – the following year, the platform added 3 million new users and catered to 5 million users in total. This increase is more than twice the number of its total user count from the previous year.

  • 2019 – ProtonMail doubled its user base from 5 million to 10 million in 2019. It was still relatively small compared to Gmail’s 1.2 billion registered email accounts at that time. In 2019, ProtonMail employed the Elliptic Curve Cryptography which increased emailing speed while providing more security to accounts
  • 2020 – during the early months of 2020, ProtonMail once again recorded a double-digit growth which sent its total user count to 20 million
  • 2021 – by this time, the Swiss emailing service provider is home to 50 million accounts 
  • 2022 – today, ProtonMail services 70 million users in 61 countries worldwide
