Brief Note :
WP Email Timer Plus WordPress Plugin allows you to create countdown timers even INSIDE your emails!
Also, this plugin will help you to increase conversions, sales and also clickthrough rate inside your emails because the moment someone opens your email, they immediately see the timer ticking to zero and urging them to take action right away.
Other than email, you will have the option to add the countdown timer to your blogs/websites as a widget.
