Best ProtonMail Alternatives for Secure Communications

ProtonMail is one of the most popular email clients on the market. In 2023, ProtonMail had over 100 million active accounts. Many people choose ProtonMail as their primary email client because of its strong focus on email privacy and security, as well as its email management features. 

If you’re reading this article, you’re likely a ProtonMail user looking for a better alternative. Maybe it’s because you want a more modern email client with a strong focus on email productivity or simply because ProtonMail isn’t fulfilling your needs. 

If so, this article will help you find a suitable ProtonMail alternative, as we’ll review the top 8 ProtonMail competitors with their features, pros, and cons. 

Why Do You Need a ProtonMail Alternative? 

(Hint: Productivity 📲)

ProtonMail is a business email provider based in Switzerland, founded in 2013. ProtonMail is known for its strong focus on privacy. Unlike other popular email providers, it uses client-side encryption to protect the content of your emails and your data before it is sent to its servers. 

ProtonMail offers advanced end-to-end and zero-access encryption for your emails and keeps your email communication private and secure. It also provides access to ProtonVPN for an added layer of security. 

Although ProtonMail attracts many privacy-concerned people, some users find its email management functionalities insufficient to support their growing emailing needs. 

Here are a few reasons why you may need an alternative to ProtonMail: 

• ProtonMail offers limited email productivity features: Although ProtonMail offers some email management features like email filters and advanced inbox search, it lacks more advanced email organization features you can find with other email clients. 
• ProtonMail’s interface can be confusing: Some users find ProtonMail’s interface a bit confusing to navigate. What’s more, it can be pretty slow to load.
• ProtonMail offers limited storage: ProtonMail offers only 1GB of storage on the free plan with a limit of 150 messages you can send per day. This can be limiting for users who require more space in their inboxes. The pro version offers more storage, but users complain that its cost is too high. 

🛠️ ProtonMail Features

ProtonMail’s main focus lies on the security and privacy of your emails. But aside from its excellent security features, it also comes with other benefits, such as:

• Intuitive web app
• Inbox customization
• Email organization with labels, filters, and folders
• Create multiple alias email addresses
• Advanced inbox search
• Access to ProtonDrive, ProtonCalendar, and ProtonVPN 

💰 ProtonMail Pricing

ProtonMail offers a free forever plan with limited features. Its pricing plans for individuals start at €3.99 per user/month (billed annually), and the pricing plans for businesses start at €6.99 per user/month (billed annually).
