Maged Daalees (ID: 0000009d0c48dce7) Voted 5 ★ - Updated 10/29/2020 This is an amazing tool, very easy and straight forward encryption for emails and attachments. Easy to use and seamless. The best part is you still control your email after they are sent, so you can revoke access or make it timed from the beginning. This is enterprise functionality for personal users. Great Job Guys.

Tobi Marshall (ID: 000000613acf876d) Voted 5 ★ - Updated 10/26/2020 Ahmed is super useful. We no longer need to put the password on every single pdf before sending the email. It will be great if we can print the email for reference though.

Tererei Aruee (ID: 0000007dadf1582b) Voted 4 ★ - Updated 06/23/2019 It's okay but what about the security of these encrypted emails in the hands of this company. Is there an assurance that these is only private to the users or not? It's better if there's a privacy agreement for this company not to be allowed to tamper their customer's encrypted emails. Thank you regards

James Mulligan (ID: 000000952ed7cb5d) Voted 1 ★ - Updated 04/20/2019 The recipient signed up to Lockmagic with their email address, then tried to view my encrypted message. They put in the password and couldn't view the message, instead got this message: "Processing...Decrypting content locally.... Done! Total bytes processed: 1168" Ok, so if it's done why can't they see the message? there's no option, button or explanation for that. This is such a waste of time
