Differences in formatting of Email template vs the actual email itself

Hello there. We have a long email that is being sent automatically to every person who registers for our events. We had it carefully formatted so that the spacing would help to clarify all of the many details included. But we found that when the email was actually received by the registrant, the spacing was totally different, and left the email difficult to understand. Can you help me understand what is going on, and/or how to correct this problem? Thank you!

It would be very helpful if you could point us to the Autoresponder that you're referring to since there are many of them in your form.

That way we'll be able to check the right one.

We'll wait for your response.

Thank you!

It is the one called "WELCOME LETTER: GENERIC"

Please note that the spacing in the email currently looks like it is poorly designed, and the reason for this is that we tried to space things out so that the resulting email would be most understandable.

Thanks for your help.

I believe the reason is because emails are sent as HTML. 

So when you edit, you might loose some of the formatting. To be 100% you could make sure the HTML is correct:

I'm sorry, I'm not really understanding your reply. So if emails are sent as HTML, then what are your emails created as? I thought they were also HTML. It would help if I knew which 2 formats we are talking about. Thank you.

The emails are indeed sent as HTML, but some email providers tend to stripe some attributes from HTML tags, so the code that can be included in an email is sometimes very limited due to security limits. 

The other email type just includes the data filled on the form fields, clearing up all the data and format. 

The default format for emails is HTML, you may find more information about the other email type by following this guide: https://www.jotform.com/help/363-How-to-Have-Text-Only-Message-Format-in-Email
