We are currently working on 64-bit versions of all our products. Apple macOS, Microsoft Windows and Linux are all 64-bits operating systems (note that MS Windows has also a 32-bit version available).
Let me explain a bit what's that about, the terms 32-bit and 64-bit refer to the way a computer's processor handles information. A 64-bit operating system handles large amounts of memory more effectively than a 32-bit system. While 32 bits of information can only access 4 GB of memory, a 64-bit machine can access 17.2 billion gigabytes of system memory! That means that your video card and other devices will not be stealing usable memory space from the operating system any longer. In addition software programs that require lots of calculations can operate faster and more efficiently on 64-bit processors.
I believe that handling more memory is very good for most of our products and they can even work slightly faster however it will be difficult to tell. The memory space available for our programs will be bigger and it will be less problematic in case of memory leak issues. A memory leak is when memory which is no longer needed is not released properly. This is a rare problem that may end with the program crashing.
Currently MaxBulk Mailer 64-bits has been built successfully. Yo can download a beta versions here: macOS | Windows
