Most people already have a free email account. If you use Apple devices, you may already have an iCloud email address ending in @icloud.com – or one of the older .mac or .me versions. That account works nicely across the Mac, iPhone, and iPad.

iCloud Mail has two big appeals for Apple users. First, it integrates into Apple’s ecosystem. It works with iCloud.com, Apple Contacts, Calendars, and the Apple Mail program. Second, it is not part of a massive corporate tracking and advertising system in the same way Gmail and Outlook are.

Proton Mail is different. It is also available as a free email account, but its main appeal is stronger privacy protection, especially for mail stored in your Proton mailbox.

Most people who use email are using Gmail from Google, Outlook from Microsoft, or iCloud Mail from Apple. Gmail and Outlook are convenient, powerful, and widely used. They are good general-purpose email services. But they are not the same as iCloud Mail when it comes to privacy.

Apple / iCloud Mail: Apple does not monetize user data through advertising. iCloud Mail also includes privacy features such as Hide My Email, which lets you create disposable addresses to protect your real email address, and Mail Privacy Protection, which helps block tracking pixels and hides your IP address from email senders. Apple gives users relatively simple tools to avoid common kinds of email tracking.

Google / Gmail: Google scans your email to provide services such as spam filtering, security checks, and smart features. Google says it does not use Gmail content for advertising, but Gmail is still part of Google’s larger data, tracking, and user profiling ecosystem. Google gives you settings to reduce some tracking and user profiling, but they can be difficult to locate. Google also has a weak privacy record: it recently agreed to delete billions of records to settle claims that it tracked people who thought they were browsing privately in Chrome’s Incognito mode.

Microsoft / Outlook: Outlook is tied into Microsoft’s broader cloud, AI, advertising, and productivity ecosystem. Microsoft accounts and Windows include diagnostic and security settings that can be difficult to locate and challenging to adjust for privacy. Outlook is a capable mainstream email service, but it is not designed primarily as a privacy-focused email account.

iCloud Mail, Outlook, and Gmail all use basic security protections, including encryption while messages travel across the internet. But among the major mainstream email providers, Apple has earned the strongest privacy reputation. Proton Mail goes further: Proton says nobody but you can access the messages and attachments stored in your Proton Mail mailbox. Even Proton cannot access them.

Proton’s free plan includes Proton Mail and Proton Drive. It starts with 2 GB of storage and can increase to 5 GB by completing simple actions. That storage is shared across Proton Mail, Proton Calendar, and Proton Drive. Proton Calendar is included, but is limited to three calendars. Proton Pass is also included. It is an end-to-end encrypted password manager, but is limited compared to their paid version.

For Apple users, the natural comparison is not the Apple Mail program. It is an iCloud Mailaccount compared with a Proton Mail account.

The Basic Difference

An iCloud Mail account is built for Apple users.

It integrates smoothly into the Apple ecosystem. It is easy to use on a Mac, iPhone, or iPad, and works with iCloud.com, Apple Contacts, Calendars, and the Apple Mail program.

A free Proton Mail account only works as webmail. You use it in a browser at Proton’s website. It does not work with Apple’s Mail program, Thunderbird, or other regular email applications unless you move to a paid Proton plan.

The important thing to understand is that Proton has two different privacy advantages, and they do not apply equally in every situation.

First, Proton says the messages and attachments stored in your Proton Mail mailbox cannot be accessed by anyone but you. Even Proton cannot access them. This includes messages you receive from outside Proton. Subject lines and email addresses are handled differently, but the body of the message and attachments are protected.

Second, email between two Proton Mail users is end-to-end encrypted while it is being sent. That means a message from one Proton address to another Proton address is protected in a stronger way than ordinary email. But this does not mean every Proton message is protected that way to every recipient.

Let’s compare iCloud Mail and Proton Mail sending to a Gmail account.

If you send a regular message from iCloud Mail to Gmail, it travels through the normal email system. The message is encrypted while it travels between the mail servers, and then Gmail receives it as a normal Gmail message. Google can scan it for spam, security problems, and smart features such as suggesting replies or message sorting.

If you send a regular message from Proton Mail to Gmail, the same thing happens on the Gmail side. The message is encrypted while it travels between the mail servers, and then Gmail receives it as a normal Gmail message. Google can scan and handle it like other received emails.

So, the Gmail side is the same: Gmail receives a normal Gmail message either way.

The difference is the copy in your own mailbox. The copy in iCloud Mail is in a mailbox Apple can technically read under Apple’s standard iCloud mail system. Apple encrypts iCloud Mail while it travels and while it sits on Apple’s servers, but Apple keeps the keys needed to read it. That means Apple could provide readable iCloud Mail if required by a valid legal order.

The copy in Proton Mail is different. Proton says it cannot read the messages and attachments stored in your Proton mailbox.

That is the important practical distinction. Sending from Proton Mail to Gmail does not make Gmail unable to read the message. Proton’s advantage is that Proton cannot read the copy stored in your Proton mailbox.

Proton also has a password-protected option for sending encrypted messages to people who do not use Proton Mail. That is different from ordinary email. The recipient receives a link and opens the message through Proton using a password you provided separately.

Proton Mail Works as Webmail

The free version of Proton Mail should be thought of as webmail.

That means you use it by going to the Proton Mail website in a browser, signing in, and reading or sending mail from there. It is not like an iCloud Mail account that you can easily use in the Apple Mail application as a normal email account.

This is a major practical difference.

If you want an email account that works easily with the Apple Mail program on your Mac and iPhone, iCloud Mail is a better choice. For many Apple users, iCloud Mail offers the best balance of privacy and convenience. If you want a separate privacy-focused webmail account, the free version of Proton Mail is an excellent choice.

Import Your Contacts into Proton Mail

Whenever you send an email to a new address, Proton webmail automatically captures that email address and its associated display name, saving them directly into your Proton Contacts. You can also import your contacts into Proton, and there is an export option as well.

Proton Mail Comes with Proton Drive

One nice extra is that a free Proton account also includes Proton Drive.

Proton Drive is Proton’s encrypted cloud storage service. The free version includes 5 GB for files, photos, and documents. That compares well with the free storage from iCloud Drive and OneDrive, which also start at 5 GB. Google Drive offers more free storage, but Google’s free storage is shared across Google Drive, Gmail, and Google Photos. Proton Drive’s appeal is not just the amount of storage – it is that the files are stored in Proton’s privacy-focused system, where Proton says not even Proton can access your data.

The free version of Proton Mail also includes other services, but they are limited. Proton VPN can be used for free, but the paid version adds more locations and more features. Proton Calendar is included, but is limited to three calendars. The free Proton Pass offers the most generous free limits of any mainstream password manager, has end-to-end encryption, but limits you to two vaults, 10 hide-my-email aliases, and limited sharing.

That means Proton Mail is not just a standalone email account. It is an entry point into Proton’s privacy-focused ecosystem. You can start with Proton Mail and Proton Drive, then decide later whether the paid version is worth it.

What You Get with Paid Proton Mail

The paid version of Proton Mail mainly adds convenience, storage, and flexibility.

Paid Proton Mail plans add more storage, more email addresses, support for a custom domain email address (like support@macplustech.com), more organizational features, and the ability to use Proton Mail with standard email programs.

Will you like using a free Proton Mail account?

That may depend on whether you use webmail as your primary way of interacting with emails. If you like using a browser for your email – Safari, Google Chrome, Firefox, etc., you will probably love Proton Mail. But not everybody likes change. Proton webmail is a clean interface with various options, but it is not Google webmail or Outlook.com.

One option is to keep using email the way you are used to doing it, but try adding a free Proton Mail account. Since it is more secure, you may want to use it for communications that are more sensitive, or require more privacy.

Perhaps the opportunity to increase your security and privacy is so important to you that using Proton webmail will be fine. You might even decide to use a paid Proton account that allows you to use the Apple Mail program. Let me know if you need help setting it up if you decide to go that route.
