If you’re managing multiple email accounts, in my opinion, Mozilla Thunderbird is absolutely the best email client you can have.
As an online marketer, I have several email addresses, all but one of them is a Gmail address. I have one I use as a primary, personal account, and the rest are for business.
I also have a Comcast email address that I set up years ago when I started using Comcast as my Internet service provider.
Web-based and Outlook vs. Thunderbird
Now, a lot of people still go on the Web to check their email, but I find it’s a real pain in the butt, seriously inconvenient, especially when you have multiple email accounts you need to manage.
And if you use email clients like Outlook or Outlook Express, you can only manage one account in the program.
