Would you use this to optimize your cold emails?

I'm undecided on an idea I've been sitting on. This is for those of you who send out cold sales emails and marketing outreach emails.

If there were a platform where you can submit your emails/templates and be able to get feedback about them from a) other entrepreneurs like yourself and b) your existing customers or audience, would you use it?

The idea is that you'd submit your template, select several questions (does this come across as spammy? would you open this email? is the request too aggressive? etc.) and people would be able to give you quick feedback (like 2 minutes to do a review). The point is to use feedback to hone your copywriting and persuasiveness.

Would love to hear some enthusiasm or criticism to help me decide whether to make something like this.
