Cold DMs are why nobody answers their inbox. A meeting request with a purpose, a length and a proposed time gets a reply. Here is the format.
The problem with most outreach is not that it is unwanted. It is that it is unclear. Nobody knows what saying yes commits them to, so they say nothing.
Asking for "a quick chat" with no agenda. Attaching a deck before anyone asked. Sending the same message to fifteen people at once, which most platforms can detect and which KONNOVA rate-limits.
Inside KONNOVA a meeting request has fields for purpose, duration and proposed times, and the recipient can accept, propose a different time, or decline with a reason. Both sides see the status. Nothing lives in a DM thread that nobody can find later.
