Number of users contactable by email

Morning all

Is there a way that I can find the number of users who I can send an email shot too in Xenforo 1? I can see the option to send a mail but I'm unsure how to count how many would receive the mail. This is for advertising purposes eg email shot to X number of users

Ignore this, figured it out. When you go into email if you tick the option at the very top that says Only generate a list of email addresses, then it spews out a list of all email addresses that you can export to excel to count. Thanks anyway, Jim
