I am not able to confirm a bulk message send.

In the Settings page, under Messaging options, there is a feature to request confirmation when sending a bulk email that exceeds a specified number of emails.

If a value is added here, when attempting to bulk email a number exceeding the specified limit, the email address associated with the user account will receive a confirmation email for approval.

You might not receive this confirmation email for a couple of reasons:

• If the admin user account you are logged in as is a generic email address such as info@, staffing@ or admin@. Please check the correct inbox to confirm.
• If the email has gone to your spam or junk folder so be sure to check there as well.
