Recently, I found something interesting in integrating all email accounts into single account. So, if you have several email accounts like Yahoo, Microsoft, and Google, you can set that those email accounts to redirect incoming message to email account you want. For example you want to set gmail for email account where all accounts are sending to, you must set your gmail account up.
Setting up Gmail:
After signing in, click gear icon at the upper-right corner, then choose “setting” in drop-down menu
Click “Accounts and Imports” tab. On the “send mail as,” add another email address that you own.
What’s great about this feature is that you can replay email from another account that’s sent to gmail account, from gmail account as that another account. 😀
