Looking for outreach tools for a small startup

We’re a small startup trying to set up a lean outbound system without stacking 5 different tools.

Main goals:
• Find and verify leads
• Run email sequences with follow-ups
• Rotate mailboxes safely
• Track replies + pipeline in one place

Not looking for something overly complex, just something that works without constant micromanagement.

I’ve been exploring tools like oppora.ai that combine sourcing, sequencing, and CRM in one workflow, but I’d love to hear what others are using.

What’s actually working for early-stage teams right now?
