E-newsletter Plugin send mail to single person at a time when you click "send newsletter now".

when we click "Send Newsletter Now" and suppose there are 3 persons who needs to send mail then e-newsletter will send newsletter to only first user and all other users are not getting mail.

But if we pause and again play the sending process it will send mail to next single user.

Could you please provide us more information about what is wrong with it? Please provide us your replay as soon as possible.
