Gmail: multiple accounts - receiving and replying from default email account

If you use google mail, here's what you can do for free:
►have all emails forwarded to your default (main) email
►have all forwarded emails automatically labeled so you'll know to where they were originally emailed
►reply from your default email as "From:" any other gmail you own without signing in and out!
►get visual and sound notification when you receive email at any other gmail account(s) you own

If you don't have a gmail account, it's easy to set up.
Create a gmail that will be your main email.  The one you give your friends and family, or the one you will use the most. This is your default email.

A new email can be for your business, for your blog or website, or even for your children if you want to be able to see if they have email without signing out of your own account.
►1.  First sign out of your default gmail account.
Sign into your second gmail account, or if you don't have one yet, click Create an Account.  You are allowed to use the same password for multiple gmail accounts.
You may have several that you want to manage from your default account.  These will all be referred to as new email accounts to differentiate from your default account.

►Remember to always scroll down to see if you need to SAVE CHANGES.

IN THE NEW EMAIL ACCOUNT

►2.  Click the gear symbol at the top right, then Settings.  
In the menu that goes across, click Forwarding and POP/IMAP, click Add a forwarding address...
Put in your default email address (that you want mail forwarded to), and click Next.  It will tell you a verification has been sent.

►If you have several to forward to your default mail, sign in to each account, and do all those now before signing back into your default mail.
►Sign out of the new account and back into your default gmail.

IN THE DEFAULT EMAIL ACCOUNT
►3.  In your default email, for each email address you forwarded, you should have an email that says Gmail Forwarding Confirmation.  Open this email and click on the link to confirm request.  Then you may delete this email.
►Under the gear symbol, click Settings, Filters, Create a New Filter.  In the To: box, put in the name of your new email (like Martysahm@gmail.com) that you want forwarded to your default email. Click Next Step.

►4.  Check Apply the label, Choose Label, New Label, type in name of new email (but not the whole email address - like "MartySahm") OR the name of a person if you are managing another email account.  Click Create Filter.

Incoming forwarded emails that are set up to be automatically labeled will look something like this.
This one is labeled "Info Morsels" -- a blog I used to have.
Labels can be any color you choose.

►5.  You're still in the Settings, so click Accounts, click the circle Reply from the same address the message was sent to.   (If you have already set up accounts in this way before now, this circle should already be marked.)
►Click Send mail from another address.
►In the pop-up window, put in your name as you want it to appear to others for this new email, and type in the name of the new address.

►NEW - now there is a setting to Treat as an Alias.  In other words, if you reply as Sam, but your default email is Tom, it will tell the receiver that Sam sent this as Tom.

If you don't want this to happen, uncheck the Treat as an Alias box.  
If you have past accounts you have already set up in this way, you can go change all of them if you want to.  Read more here.
►Click Next Step, Send Verification.
►Close window.

You are still in your default email.
►Again, if you are doing this for multiple accounts, while still in your default email, repeat steps 3-5 for each email address.

IN THE NEW EMAIL ACCOUNT

►6. Then sign out of your default email, and back into the new email.  There should be an email for you to confirm that your default email can send mail "as" your new email.  Confirm by clicking the link in the email.
►Also, click on the gear symbol, and go back to Settings, Forwarding and POP/IMAP, and make sure the circle is ticked beside "Forward a copy."  Save Changes.
Sign into and do this for each email you wanted to send mail as. 

 

Now sign back into your default email.

IN THE DEFAULT EMAIL ACCOUNT

►7.  Click Compose mail.  In the From:  line, click the drop down menu, and click on the new email address.  Now you are sending email from your new email while still in your default email.

All email including replies to your new email address will be sent to that new email address and forwarded to your default email account.
You're done!  =)

►You can also create labels for anything, and apply them to any email after you receive it. Videos, Pictures, Important, etc.  Just checkmark the email you want to label, click on Labels, create new, and type in your label name, then Ok.  Then if you want to Archive (file) an email, you can find it again by clicking on the name of the label in the sidebar of your email account.  This is like a folder.
Do not archive until you have attached a label, or it will be difficult to locate again.
Under Settings, Labels, you can decide which labels (folders) you want to show in your sidebar.

►To get visual and sound notifications of any new mail even if your browser is not open, get Gmail Notifier.  It displays an icon in your system tray that is white when there is no mail, blue when you have mail.  Notification sounds when you get incoming mail.  Now you'll know if you've received email in any gmail account you own!
