Depending on how many recipients you have and if you want to customize each message, there are alternative methods, such as simply addressing your message to (every contact in) an address book.
(be aware that if you do not use your own mail server, your internet provider may impose limits on the number of messages that you can send out in a session or during a day, or how many people can be on the BCC address line of a message, et cetera.)
