You have decided to change from your current email address to another. How do you inform everyone that you communicate with, your new email address?
The easiest way is to create a list of all your corespondents' email addresses by entering them into a distribution list.
Once the distribution list is created, you can send an email to the distribution list that states that your email address has changed, what it has changed to, a request for your corespondent to update their address book with the changed email address and a cutoff date when your old email address will no longer be valid. Once the email is sent out, you might get messages that one your email is undeliverable. More than likely this is because the email address you tried to send to is out-of-date and is not longer valid.
In conjunction with the email sent to your distribution list, email applications like Outlook allow you to auto-reply to new email messages. The auto-reply would have a similar message to the one you created for your distribution list.
All the websites that require an email address to communicate with you will need to be updated one by one. One way to accomplish this is to make the change when you need to access the website.
