Hello, we've contacted Trend Micro, and they have indicated that the s.mmgo.io domain is now classified as "Safe - Business/Economy". Let us know your experience!
Hi Jim,

Currently the API only works with specific end date times as inputs. This can be added to the timer URL as a token (as shown in the example) or as plain text date. This option only works if you have a way to pass an end date time specific to a customer into your email template.

In the future, we'd like to add a way to insert a duration. So for example, you'd be able to indicate a certain date (today's date) + 24 hours as the end date. The embed code would look something like this: <img src="...?endDateTimeToken=cjyCXDJBz73MDKo%2b6vGYlNLrBDfu9miZmshGelMycRs%3d?hours=24" /> Most email marketing services, such as MailChimp, provide a way to insert today's date into your template.

Would such a solution fit your requirements?
Since Outlook 2007 does not support animated GIFs, we fall back to showing only the first frame of the timer which statically displays how much time is left. There's currently no way to set this manually.
Hi, thanks for trying Motion Mail. We see generally very high delivery rates, but since the service is somewhat unique, sometimes providers mistakenly block it.  We have submitted a request to Trend Micro to unblock the image domain. If you see any other problems please let us know.
Hi Jim,

With our API you can add an end date time token to your embed code, which allows you to reuse the same timer with a personalized count down. It depends on the flexibility of the system you're using to send out these emails if it can be integrated with the MotionMail API. For more info on the API and an example check out the last question on our FAQ: https://motionmailapp.com/dashboard#/faq

Feel free to contact me if you have additional questions on how to get this set up!
We've tested the timers accross all popular email clients and most render the countdown timer correctly. Unfortunately, Outlook 2007 does not support animated GIFs, which means that the countdown timer won't work as intended but instead falls back on a static image.

Thank you for the detailed follow-up. We haven't received a response to the message we sent Media Temple yet. I'm testing out an potential alternate solution in case they refuse to white list our domain.
We are also working on developing new timer styles to add to the four existing ones.
Hi ho1ooho,

We introduced a new font a couple of weeks ago to match the digital clock look you suggested. See an example below:

The flip clock design is not possible in our current implementation. We will keep your suggestion in mind for future iterations.
