Email Autoresponder: Request to allow voice recording attachments

Creating an auto response email with attached voice recording 

I have a word press.com website. I have created a Jott form contact form that is embedded on my site. I am trying to set up an email auto responder with a attached voice recording file. In settings when I go to advanced, and select attach a file to upload, it is not letting me upload an MP3 or a M4A  file. How do I go about doing that? I have watched many of your online videos and read many of your tutorials and have not been able to find an answer to what types of files can be attached as well as what size files can be attached. Any assistance you could give me would be greatly appreciated.

At this time the 'Attach a File' works for the following formats:

application/pdf
application/doc
application/msword
image/png
image/jpg
image/jpeg
application/vnd.openxmlformats-officedocument.wordprocessingml.document

Unfortunately, the audio and video formats are not supported. I will add a feature request ticket to see if the audio attachments can be allowed at some point.

You may consider uploading your file somewhere, and then including the file download link to the email autoresponder template.
