Maskmail vs SimpleLogin

Looking for an email aliasing service and trying to decide between Maskmail and SimpleLogin? Both let you create masked addresses that forward to your real inbox, but they take different approaches. Here is an honest breakdown.

What is SimpleLogin?

SimpleLogin is an open-source email aliasing service acquired by Proton AG in 2022. It generates unique aliases that relay messages to your existing inbox. With browser extensions, mobile apps, and deep integration into the Proton ecosystem, it has become one of the most popular aliasing tools on the market.

What is Maskmail?

Maskmail is an email mask firewall. You create one mask per service, forward what matters to any inbox you already use, and disable any mask the moment it gets abused. It supports custom domains, delivery history, threaded two-way replies that show who sent the email at a glance, and usage-based pricing.

Feature comparison

Pricing

Maskmail charges $0.99/month base plus $0.006 per email sent or received. You pay for what you use, and light users pay very little.

SimpleLogin offers a free tier with 10 aliases and 1 mailbox. Premium costs $4/month (or $36/year) for unlimited aliases, multiple mailboxes, and custom domains. Premium is also included in Proton Unlimited, Proton Duo, and Proton Family plans at no extra cost.

Where SimpleLogin is stronger

• Mature ecosystem. Browser extensions for Chrome, Firefox, and Safari, plus native mobile apps. The alias creation workflow is polished.
• Open source. The entire codebase is auditable, and you can self-host if you prefer full control.
• Proton integration. If you already use Proton Pass or Proton Mail, SimpleLogin aliases are built right in.
• PGP encryption. Forwarded emails can be encrypted with your public key before they reach your inbox.
• Flat pricing. One monthly or yearly fee covers everything with no per-message costs to think about.

Where Maskmail is stronger

• Usage-based pricing. At $0.99/month plus $0.006 per email, light users pay significantly less than SimpleLogin's $4/month flat fee.
• Threaded replies with sender context. Forwarded emails show the original sender's name in your inbox. Hit reply, and the conversation threads naturally for both sides while your real address stays hidden.
• Delivery history. Track every forwarded message at a glance and catch issues before you miss important emails.
• No ecosystem lock-in. Maskmail is a standalone service with no ties to a larger product suite.

Something to consider

Since its acquisition by Proton in 2022, SimpleLogin has become increasingly tied to the Proton ecosystem. That is great if you are already a Proton user, but if you are not, it means your aliasing service now depends on the priorities of a much larger company. Some users have also found that 10 free aliases run out faster than expected. Once you hit the cap, every new signup means choosing between paying $4/month or reusing an old alias, which defeats the purpose of one-alias-per-service isolation.

If you find yourself wanting a standalone aliasing tool that is not attached to a broader product suite, and where you only pay for what you actually use, Maskmail might be a better fit.

Who should pick which?

Choose SimpleLogin if you want a mature, open-source aliasing tool with browser extensions and Proton ecosystem integration, or if you value PGP encryption and self-hosting.

Choose Maskmail if you want lightweight, usage-based pricing, delivery visibility, and a focused aliasing service that stays out of your way.

Bottom line

SimpleLogin is an excellent service with a proven track record. Maskmail takes a different approach with transparent pay-per-use pricing, a delivery history dashboard, and a lean product focused on one job: keeping your real email private. If you are looking for something simple that just works with any inbox, Maskmail is worth a try.
