If you’re thinking about using Instantly for cold email, this is the review you should watch first—because picking the wrong tool can wreck your deliverability, send you straight to spam, and burn through domains with nothing to show for it. I spent the last few weeks testing Instantly.ai and broke down what it actually does well, what it does poorly, and what you need to watch out for before you scale. The big idea is simple: your cold email platform isn’t “just software”—it’s the foundation of your outbound system. In the video, I walk through Instantly’s core features: unlimited email accounts (their biggest advantage for scaling), built-in warm-up with inbox health scores, Smart Delivery testing to see inbox vs spam placement, and campaign tools like sequences and A/B tests. I also cover the real-world downsides: the UI isn’t intuitive, the lead finder isn’t as strong as dedicated tools like Apollo, and Smart Delivery uses paid credits. My verdict: if you’re doing B2B outbound at scale (roughly 50,000+ emails/month), Instantly is one of the best infrastructure choices in 2026—just don’t ramp too fast and assume the tool can fix bad targeting or copy.
