What's your go-to stack for customer outreach and relationship building?

I've been experimenting with different approaches to customer outreach for my SaaS, and I'm curious what's working for others.

My current challenge: Balancing automation with authentic relationship building. I've tried tools like Waalaxy for LinkedIn outreach (fast but feels spammy, 1% reply rate) versus manual research and personalized messages (time-intensive but doesn't scale).

What I've learned:

• Generic automation kills engagement

• Manual outreach works but isn't sustainable

• Finding the sweet spot between efficiency and authenticity is tough
  

Questions for the community:

• What tools do you use for customer research and outreach?

• How do you maintain authenticity while scaling your efforts?

• Any creative approaches that have surprised you with results?

• Would love to hear what's working (or not working) for other founders here!
