If you have recently imported data into your database that included email addresses, you were presented a dialog upon completion asking if you would like to send us an email to enable those addresses.  Recently we had to change the password on the account that sends those emails we broke the darn thing.  It provides no indication of success or failure, so you thought you were sending them and we were wondering why weren't getting any of those requests. 

It has been corrected, but it won't be available to use until our next release (TBD).  

In the meantime, if you import any email addresses that you need enabling for mass email, please send an email to support@trailblz.com.
