Whatever the case, there are a few things to keep in mind when evaluating all email clients: How fast is the setup process? How easy is it to use? Is it secure? What are the sorting options for your inbox? Is it nice to look at? Security could be your top priority if you work with sensitive materials, or you might just need to easily manage multiple accounts. You might be a power user, comfortable with running macros to make the most out of your email experience, or you might just want something that works out of the box without having to fuss with settings.
So what’s the best email app for Mac then? Depends on what you do.
