Thank you for reaching out to the Constant Contact Community. It's my pleasure to assist you today. I'm sorry you aren't receiving your test emails. I have done a test and was able to receive your email, so I believe you may be running into a firewall within your server blocking your email from being delivered. This issue can be corrected by whitelisting Constant Contact in your security settings.
In regards to the RSVP block, those results are tallied in the Email Details section of your reporting on the email. Please feel free to reach out should you have other questions. Thank you for choosing Constant Contact. Have a great day!
