Hi Matto3436! So sorry the notification emails are looking wonky. 

About email notification customization; since I can’t explain this any better than my co-worker did I’ll refer you to her answer → Email Confirmations

Sorry you can’t get your post meeting email to send. There could be a few different things going on here. If you are using the email follow-up feature, I would start by making sure it is turned on. Go to the Event Type you’ve created and on the left navigation bar is a Communications section. From there hit the three dots under “Email follow-up” and make sure it is turned on. This is also where you can control whether the Reply To address is a do not reply address or your personal email address.

If you are using a custom Workflow, again, I would make sure that is also turned on. That is in the same area. Worth noting that sometimes follow up emails built in Workflows are applied to the wrong event type. From a user perspective it looks like they aren’t functioning at all.

Thanks for the response, I finally was able to get the response emails to send but the next question is are there any tips in formatting?  The response gets a tremendous amount of spacing added to it which makes it pretty unusable.

Email notifications shouldn’t be sending with excessive spacing. It’s a little difficult to diagnose the situation without seeing specifically what is happening. Feel free to attach an image and I can try to troubleshoot. I can say that if you are pressing ‘return’ after each line that will create a new paragraph, an issue we’ve seen in the past. It might, however, be quicker to contact support and let them view your screen remotely. Contact them here → Customer Support
