Email Newsletter deliverability

Hey guys,

Im looking to setup a newsletter(html) with a bunch of video thumbnails embedded in them...Each of this video will also have a text area field below them that allows users to write comments to the videos and hit submit. Would having forms and submit buttons in the email body affect the email deliverability? What would I need to keep an eye on, to make sure that a email newsletter like this doesn't have email deliverability issue.

Thx,

Some email clients will consider forms in email as security risk and therefore they will be removed or disabled. Even if they got displayed, user will get warning about submitting their input information to external source.

When you design email newsletter, you should really code it as people did 15-20 years ago - using tables and with bunch of inline codes.
