It´s hard to see you go! But we still want to help you with your transition.
Update your contact information on websites that still have your old StartMail address. For example, if your bills are emailed to you, log in to your biller's website and change your contact information to reflect your new email address.
Send an email to all the contacts in your address book to notify them of your new email address.
Export your address book from your StartMail account.
