How to know which email addresses in my contacts are inactive?

How do I send the same email to a list of 100 email addresses ?

• I use Yahoo mail to send emails. I want to send the same message to 100 email addresses.If I type in the addresses and send the message, the next time I want to email the same 100 people I will have to re type all the addresses again - How do I enter the addresses so I can save them ? in Add contacts it wants first name,surname,etc etc etc -All I want to save is the email addresses( which are neither friends or contacts) How do I do this do you know ?

• Answer:

  First you must put them in your contacts. If there is no name then just use name1, name2, etc. Now create a category (add category button) and add about 50 names to it. You will need 2 categories. Even through Yahoo allows 100, if more than 50 go to yahoo.com it will not work. Now when you send the email use the category name in the BCC field. You can use TO but they will be hidden if you use BCC. You may have to wait a few hours between each batch or Yahoo may treat it as spam. NOTE: You should use BCC or name1, name2, etc will show up and that may look strange. Also it hides the list of addresses from others. ₪ ʎəɿʞɹɐq ₪
