How do you get early users to talk to you when cold outreach reply rates drop?

I used to rely on personal messages on LinkedIn to get early feedback for new features, but over the last few months the reply rate plummeted.

It feels like automated AI sequences ruined cold messaging for everyone who’s actually trying to have a real conversation.

I'm trying to figure out where people actually engage without filtering you out as spam.

Have you had better luck switching over to Twitter/X DMs, cold email, or just building relationships inside smaller communities?
