Yes - if you send a PGP encrypted email (from with-in or outside mailfence), your recipient will receive an encrypted (unreadable) email and will require his/her private (decryption) key to decrypt and read that email.
See this 'how to' manual for more details.

> Yes, we do keep our system logs for limited time, as to investigate any related issues that our users may face.
> Suspension of Basic (free) plans after 7 months of inactivity and final deletion after 12 months.
There's no inactivity period for paid plans.

We thank you for your feedback and will remain at your disposal.

7 months inactivity limit for a free account is a very reasonable time :)

I fear that I, as a rookie, would struggle in understanding how to indicate which mails should be sent encrypted and which should be sent unencrypted. A lot of my friends and family use Gmail, Yahoo or Hotmail, and don't have the knowledge how encryption works. So it'd depend on me then, but I too struggle in understanding how to indicate whether an email should be sent unencrypted or encrypted ...

For how long can one see the date(s) of previous sign-in(s)?

This indeed is a common concern, and I would recommend you to have a look at the recent interview of one of Mailfence's founder Mr. Patrick which might help in forming your opinion on that.

We've put an immense level of efforts towards providing an easy-to-use solution without compromising the security over convenience. Our "how-to" manual will further guide you in this regard.

You can see the previous sign-in date on your every account login (after which the previous sign-in date, time.. will be flushed). This is to actually help users in identifying any suspicious activity related to illegal login's/account abuse...etc.

Can we use our own domain with mailfence?

What about aliases? What's the number of aliases in your domains? and in our domains?

I prefer emails whose sign-ups do NOT require you to provide an existing email somewhere else.

Yes you can.

You can have 10 aliases with paid plans on our domain, and this number is negotiable for a custom domain.

We understand your concern, and have planned to make it optional in the future (its only a matter of time now).

Thank you for the reply.

I was going to test your service but unfortunately, you still require an e-mail account in order to create an e-mail account. I'm eagerly awaiting the time when it's optional.. Seems to be an interesting service.

I wonder if you plan to merge the e-mail and documents space in the near future? I prefer when e-mail providers make no destiction between both, in regards to space.

Can I double-check with you about the inactivity limit?

You're saying 7 months, but I'm pretty sure I saw 2 months limit stated on your website. That meager 2 months was a major downside for me.

"Free accounts are therefore suspended after 60 days of inactivity and totally deleted after 90 days."

We'll let you know when it'll become optional. Besides, keep on checking our blog and subscribe to our twitter/reddit for getting all the latest updates.

Both email messages and documents are two separate sections within your mailfence account (in regards to space) and have their own separate data limits (based on the subscription plan).

Thank you for your feedback, and will remain at your disposal.

To re-affirm,
> Suspension of Basic (free) plans after 7 months of inactivity and final deletion after 12 months.
There's no inactivity period for paid plans.

Thanks for notifying that, we'll update the whole FAQ soon.

I had been in touch with the helpdesk of mail.be/ContactOffice (which I'm not sure would be the same staff as the helpdesk for those using MailFence) regarding the inactivity limits. They said there was a mistake about that on the website and that they'd make the change to correct that info.
