I went into this thinking I was going to disagree because honestly I hate recruiters and the time-wasting involved but I actually agree.
Here's why: by having a template that he just copy-pastes. This is extremely low effort and will filter out a lot of recruiters. I also agree with working with company recruiters over third-party recruiters.
The first thing many recruiters will want to do is "hop on a call". Resist this urge. In fact, don't even give them your phone number. Force them to use email to contact you. A phone call is a good way of wasting your time. If you actually need to call them on the phone, call them.
There are lots of techniques recruiters will use to waste your time. One common one is if pressed on compensation range you'll get the answer that it's "competitive".
Use a template like this to simply filter out time-wasters. If they want to get on a call, resist giving concrete details or otherwise just give you bad vibes, just stop responding. They can't call you. They don't have your number. Move on.
