Hi Paul, Thanks for the explanation. Now I understand how the build was intended. FAQ explanation would be helpful to the community :)
Hi Paul, Thank you for being open to suggestions and implementing this one!
Looking forward to this feature being implemented
If somewhere down the track, you decided on a free/paid business model for MotionMail, you could have different options of this suggestion for the varying plans.

Example:
a) Free plan: When clock runs out, MotionMail could display an Advertisement to generate some ad revenue for yourselves or a Static Image to drive more traffic to your own service (Countdown Clock by MotionMail. Click here to get yours Free).

b) Paid Plan: When clock runs out, users can customize the clock to have
- a static image/message as Rick had mentioned, that can direct traffic else where. This would be controllable within the clock setting in advance so when the end date/time is reached, it would click over automatically.
- integration with AdSense to allow us to display ads in it's place when clock runs out.
- or simply just choose to have the clock show 0's indicating to new traffic that the clock/sale has run out.
