I have over the years hade 3-4 websites and email addresses, blogs. I want to find a way to go one place to access all of them.
Use Gmail to import everything into one account. https://support.google.com/mail/answer/21289?hl=en
It's a good idea to keep accounts separate though if they are for different purposes. You can setup filters in Gmail for important emails. I also find it very helpful to use Google Chrome's User Accounts to easily switch between different Google accounts. Feel free to call me at 812-650-4405 if you want to discuss this more.
