Here at Playable (https://playable.video/video-email/) we recommend maximum duration of 10 seconds, we have found this to be the optimum duration when you are seeking to deliver a good video experience for all recipients regardless of their connection type, speed and type of device.
Joining this thread some 3 years in so had the benefit of time for things to evolve in the Video Email space, in a positive way :) As it is now fact that you can reach 95% of your email audience with Autoplay video embedded within your email., the tricky 5% is predictably Outlook desktop.
I have linked to a video tutorial below specifically shows you how to embed short Vimeo video clip within your email and send via any of the popular ESP's, without a hitch. Tutorial is here: https://playable.video/project/how-to-include-a-vimeo-video-in-your-email-campaign/
Hugh Hi, last year we conducted some analysis on the best video media formats for email, the research considers a sample of over 1 million so is pretty robust. The full write up on the analysis can be found here: https://playable.video/project/why-embedding-video-in-email-is-better-than-adding-a-gif/
Peter Hi, Your assumption is partly true, in that yes we do send a Gif to some recipients. The file type received by each recipient is dependent on their device connection type and connection speed, which we detect at the moment the email is opened. Our objective is to deliver the file type which which delivers the very best "video" experience res;alive to the conditions we detect. This report shows what file types we delivered across 1 million sends, clearly indicating we are much more than a GIF generation platform : https://playable.video/project/why-embedding-video-in-email-is-better-than-adding-a-gif/
Victoria Hi, we've developed a SaaS which enables you to embed a YouTube video within your email, which autoplays at the moment the video is opened. We simply grab the video using the YouTube link. Full details on our approach can be found here: https://playable.video/video-email/ hope this helps David
Audio within email is possible, but it does have some limitations, in terms of which email clients you can reach with the audio. We have created a table here to indicate how each of the major email clients treat Audio: https://playable.video/blog/video-email-with-native-audio/
Further more we have outlined how audio and video can be streamed into your email campaigns, with an example you can experience here:
Hope this helps
James Hi, The 95% number comes from analysis of 1 million video email sent during September 2017. Clearly this number may vary depending on the makeup of your list (% of outlook domains being a key determinant), but also bear in mind Video works fine for outlook when viewed on Mobile, where as you'll appreciate an increasing majority view their emails. The study results of the 1 million emails referred to above can be read in full here: https://playable.video/project/why-embedding-video-in-email-is-better-than-adding-a-gif/
Leigh Hi, I concur with Vadim, Video is not supported by Outlook on desktop, only on mobile. Outlook 2003, 2007, 2010, 2013 and 2016 for Windows all do not support Video. The good news is that you can reach 95% of your audience with video which plays at the moment of opening, with the Outlook desktop recipients seeing a static image and appropriate call to action to view the hosted video on line. We've built a platform here at Playable to make the embedding of video in email really simple, the solution works with all video formats and files and your campaigns can be sent using any of the popular ESP's. You can check out how it works and see some sample campaigns here: https://playable.video
