How are you actually finding decision-maker emails at scale?

Hey everyone, I need your guidance.

I’m currently building a system to automatically find decision-maker contacts (especially emails) for a chosen industry and store everything in Google Sheets. For the next few days, my only focus is getting the right contacts reliably. Outreach, personalization, booking calls, CRM updates, that will come after.

I know many of you here have already built and are running systems like this successfully, and I really want to learn from your experience.

If you’ve done this before, I’d love to hear:

How does your actual workflow look end to end?
Which tools are you using today (and why)?
What fields do you store that actually matter in real usage?
Any templates, references, or existing workflows you’re willing to share?
What mistakes should I avoid early on?

I’m intentionally not over-engineering this yet, I want to understand what works in the real world, not theory.

Your suggestions would be extremely valuable for me and for others trying to build similar systems.If you’ve already cracked this, I’d really appreciate your support 🙏

Best,
