A more fleshed out web interface for sending and opening mail would be much better Review source Non-incentivized review: any software user can leave a review for any product listed on our site.

I believe that Mailock are in regular contact with financial services providers with regards to their software but most are still unable to accept or open emails from Mailock. This doesn't help when we are trying to communicate securely with providers. Pros Mailock was introduced into our firm to improve the security of our communications with our clients and providers. The software is easy to use and I specifically like the prompts to secure emails with key words. Cons We have experienced a huge amount of trouble using the software to send information to providers in the financial services industry. Most providers have reported that they are unable to open encrypted emails from Mailock and we have had to resort to sending information requests by post. Not ideal when the purpose was to send information securely to providers. Review source Non-incentivized review: any software user can leave a review for any product listed on our site.

Our clients tell us all the time how much better our encrypted email is easy to use. Pros It is easy for the recipient to open encrypted emails. On the company side, using the software is intuitive and straightforward. The best encryption email out there and we have tried a lot. Cons No cons only a couple of wish list items - 1. SMS for USA. Only in England so far. 2. Add Signature block for the online version. We do not use the desktop Outlook and use Outlook 365 instead so there is no signature integration.

RE Reviewer Technical support Used the software for: 1-3 years ### "Mailock Review 2023 " 5.0 August 18, 2023 Overall Mailock has been very beneficial to the company in allowing us to send messages and documents securely and relatively simply. Pros The integration of mailock into our business and daily routines was relatively simple. It's very easy to use when sending and receiving messages and the ability to set up an account, which provides free messages each month for client's to send, is a real benefit. Cons It would be beneficial if, once a client has set up an account with one person in the company, the account was linked to all people within the company. It can be difficult/annoying trying to explain to client's why some of us still have to send the client a code, even though they have set up an account. It would also be good if messages didn't expire, as client's like to look back through their messages.
