Some areas of Proofpoint proved to be a bit difficult to customize for our organization.

ICT Infrastructure Manager

Good overall product; sometimes difficult to configure / customize, but surely one of the best in terms of update and protection.

Quarantine interface is bit complex to use and manage.

Easy integration with Outlook 365, friendly management console

information security engineer

They have amazing signatures, GUI is easy to learn which shows how many users received malicious emails and how many of them clicked, which helps in the investigation.

ProofPoint Essentials provides a complete line of email protection tools, such as simple spam protection, phishing protection, URL and attachment sandboxing, encryption, emergency inbox and archival.

Bad customer support, sometimes too many true positives are there which can be dangerous for a firm.

Systems Engineer

We rely on PPF for our org's email protection including TAP/TRAP/ spoofing and spam protection.

Service Manager

Proofpoint Email Protection has allowed us to increase our email marketing reach without the fear of breaches to our data and security

The ability to generate a mask email address is fabulous and the integration with the brilliant suite of other Proton products is seamless.

The snooze function is great, the folders simple to create and the spam folder is intelligent, effective and means you don’t have to go trawling for that email you missed.

The concise, clarity of the layout, it’s unfussy nature yet powerful encryption, filtering and privacy features are all glorious.  

Developer

It has great privacy and does not use your info for advertisements and sells info to other companies.

The UI is not that great, Switch between other mails is annoying when using a lot of emails.

The fact that it is independent of the US based tech beasts, means that you can use it safe in the knowledge that you are not being tracked.

It is great for security ( no questions )  but the UI and integrations with other services still needs a lot of work.

Owner

The layout is clean, the apps are stable, and switching between Mail, Pass, and Drive feels seamless.

We don’t get any spam, which is worth its weight in gold. While Proton is known for its encryption and privacy, that wasn’t our main reason for choosing it.

We’ve been using Proton for our business email, password manager, and file storage, and it’s been a great experience.

Director

I had operated a free ProtonMail account for some time, but since I was also using their VPN and password management products, I decided to pull the trigger and upgrade to "Mail Plus" -- unlimited daily messages instead of the weak 150-message limit for a free account, 15Gb of space on their "Drive" storage utility, etc.

Founder

ProtonMail does a great job of keeping email simple (as much as every other email provider you may have experience with) but at the same time with a lot of powerful tools, likeHTML signatures, SIEVE filters, email aliases, many security options (E2E encryption by default, but also Sentinel and session management), trackers blocking, and a privacy-by-default and privacy-by-design policy (some of these are premium features for paying customers).

I wanted a reliable e-mail service I could use for my freelance work and a few of my personal websites that did not harvest all of my data.

Marketing Specialist

It’s encrypted by default, so I don’t have to flip a switch or check any settings.

MXRoute offers unlimited custom domains (and a lot of other cool things Proton does not) for a lifetime price that is equal to a yearly subscription to Proton, so I went with them.

The email service has enhanced security and encryption with  a schedule send feature very useful for drafting and sending messages later

That’s genuinely difficult to answer.  

ProtonMail prioritizes privacy, has a sleek UI and valuable features like schedule send.

A lot of the problem I'm solving has to do with 19 years of wrangling a Gmail inbox until it became a hot mess of unread emails from lists I didn't remember subscribing to.

This means that all of the addresses I created for custom domains were deleted (luckily I had already migrated them).

Using other clients requires installing and configuring protonmail-bridge (a sort of e-mail proxy).

Postdoc

Has most features of famous email service providers.

My only option is to purchase a significantly more expensive monthly subscription for 5 months (instead of the 9 I had left).

It's not "free" like Gmail and some other offerings, but it's solid, it's simple, it's privacy-centric, and it offers the features I need.

The biggest win for us is how easy it is to use.

I deactivated my subscription with 1 year remaining and instantly lost access to *all* premium features without any warning.

Writer

ProtonMail offers fully encrypted email messaging with all the features you know and love from providers like Google and Microsoft...but without the snooping. If you care at all about privacy and security online, Proton should be your one-stop shop.

Student

My overall experience with ProtonMail was that it is a good option for users that those who seeking for more privacy and security.

Technical Support Specialist

I love the security features, how well all the spam filters works, that my email are devliered without any issues and that it blocks and scans attachments.

I begged support to convert my credit to a SimpleLogin or even a Proton subscription but they refused.

Even Google lets you use the remainder of your subscription when canceling...

Student 

The storage limit can be increased even though we have to upgrade it.

System Administrator

This has proven critical feature that I often use in my daily emailing tasks.

Content Writer

I used it briefly with my domain to get a custom email address, but it didn't have all of the features that I needed to run my freelancing business.

Maybe ProtonMail was at some point customer-oriented. But my experience with them has been the opposite: overpriced, restrictive, unfriendly money-grabbers.

Niche Growth Facilitator

ProtonMail is an encrypted email service that uses end-to-end encryption to protect your data from prying eyes.

ProtonMail offers a free version of its email without ads, a refreshing difference from Gmail scanning emails to show you ads.

clinical investigtaor

Well every great service has its flaws for this is their GUI, messaging limits and some features are only available  for paid and it is some what expensive compared to other service providers.

Unfortunately there is not much feature parity among platforms.

mixer/production

quick and nonintrusive account creation, ability to use temporary accounts, data is not stored and sold.

The features of different platforms doesn't needed to change and can be kept same.

My company decided a few months ago to use Proton as its main email server due to the level of security it offers in terms of message privacy.

I am not yet at the point of upgrading but still i feel this storage should have been bigger.

Eventually, I decided to migrate all business-critical mail away from Proton.

Energy Consultant

I have one for personal the. free version of this is more than enough for any user.

Nail artist

There was a feature that eaily copied my folders and emails over from most recent ones sent (last 3 months)

ProtonMail also has a built-in VPN, which means you can be sure your data is always safe and secure.

The most attractive feature of this product is its user interface which is both attractive and easy to use.
