Double opt in intros are obsolete and too slow for the pace of modern business.
Just make the intro. The introducer owns making a value judgement, the intro target owns ignoring if they don’t care, and the introducee owns dealing with it if nobody cares.
A good Introducer makes a thoughtful summary of the perceived value to both in connecting. In time, you either build or erode your social credibility as you demonstrate your level of ability to perceive the value of connections.
