For that same reason, you don’t have the same storage limitations as webmail servers. Basically, you can store as much email as your hard drive can handle. But be warned, your Mac Mail will run slower if the number of emails in your Inbox approaches 100K; at that point, you’ll want to archive your old emails.

For example, let’s say you want to manage your personal Gmail account (janedoe@gmail.com) and your work email (janedoes@mycompany.com) in the same email application.

Mac mail allows you to do this! You can also set up an iCloud email account that easily syncs with other Apple devices. If you’re performing the majority of your email activity from your Mac computer (not on mobile) then Mail is a great choice. You can also set up your mac mail email signature.

Which one of the best email clients is right for you?

Choosing among these various email providers will depend largely on how comfortable you feel with the design and interface.

Each email client offers similar features when it comes to email productivity and security. It really does come down to a matter of personal preference. Most offer a free version of their service, we recommend opening a free account to give the provider a test drive before you commit.

The other thing to consider is how much does your current email address matter to you?

If for example, you are a freelancer who has been doing business from your Gmail address since 2007, you might be best off sticking with it than switching to another webmail provider.

Migrating to a new email address isn’t difficult, but it is a process. You will risk losing contacts if you aren’t meticulous about how you implement it. Inform people about your new address. If, however, you are looking to open a brand new account for your business, now is the time to explore each client to get a feel for the interface.
