Speaking from experience, it's a bad idea to allow emails to be sent from your platform to a third party with any form of dynamic text from a text field on a web page. I can't see this lasting long term in its current form.

I had a form readers of my blog could fill out to contact me. It asked for their name and email address. After they submitted the form I sent them a nice automatic reply along the lines of:

  Hello <name>,
  Blah blah blah.
  
  Thanks,

This was integrated with my personal gmail account. One day I woke up to a ton of bounced emails. Checking my sent folder, a ton more didn't bounce. The name field was enough for a spammer to co-opt my contact form into a spam mailer.

Regardless, I think this is needlessly passive aggressive and not a good way to handle something like this in general. For one, I think there is a good chance the recruiter will still know who sent the message. It's a small world. Why burn bridges?

I know how it feels to never get a reply back. Yes it is frustrating. I just don't think this is the solution to the problem. Someone being unprofessional to you is not justification to be unprofessional to them. Reputation is a two way street. Don't let others catch you on the wrong side of the road over something like this.
