Administrator and owner

Protonmail Bridge often randomly logs out, and then it is a bit of a pain to log back in and sync everything up. The spam filter is sometimes too aggressive and hides legitimate mail.

Artist in Residence

I love that there is no spam and for this reason it is also a good email for children. Messages can be encrypted between users which is helpful and fun aswell.

I am absolutely thrilled with the Proton range of services and can rest easy knowing my clients data is safe.

The free version is very powerful, you have everything you need. However, in the pro version you have more storage space, the mail is faster and the technical support works great.

Principal

But when you run into some difficult, you discover there is NO phone support. When you file a "bug report" you get a response, and usually a tech will response via email in 24 hours.

Owner

My experience has been 100% positive, I integrated my proton account with my custom domain and use it as my business email platform as well as for my personal emails.

After the trial I payes for a subscription and integrated the mail functions with my domain name. I also got ProtonDrive, ProtonVPN and the ProtonCalendar, all secure.

Project Manager

They have paid subscription,however the free version should be enough in itself for most people. You can import your signature or create it on ProtonMail.

They have recently expanded by adding storage to protonmail, which was long needed. Their customer service that used to take ages is getting a bit faster as well.
