Alright—Instantly.ai is a beast when it comes to cold email. I used it for high-volume inbox rotation, warmups, tracking—basically a full email machine. But it’s not perfect. No built-in lead database, no deep enrichment, and campaign reporting is a little limited if you’re scaling hard.
So, here’s my list of the best tools to either replace or pair with Instantly, especially if you need a B2B Lead Generation Tool with more features, better data, or just a different workflow.
1. ZoomInfo – Enterprise-Grade B2B Leads Database

How It Works
-
Search by job title, company size, industry, tech used, and more
-
Get verified contact info with email + phone + role
Why I Used It
✅ Wild amount of data
✅ Best for ABM and high-ticket sales teams
Why I Switched
❌ Expensive as hell
❌ No built-in email outreach like Instantly
