10 Cheapest Cold Email Software Tools
For Startups & Agencies
Cold email remains one of the most cost-effective growth channels — but only if the tooling makes sense. We tested 25+ platforms to find the best budget-friendly options that actually deliver results.
Finding Tools That Won't Break Your Budget
Paying enterprise-level prices before proving outbound is one of the fastest ways to burn budget without results. That's why many early-stage teams look for the cheapest cold email software that still supports deliverability, personalization, and scale.
Key Insight
Most startups overpay for features they don't use. The right tool should grow with you — not force you into expensive tiers before you're ready.
How We Defined "Cheapest"
This list isn't about tools that are "cheap" but unusable. To qualify, a platform had to meet at least three criteria:
Some tools are fully paid, some are freemium, and some overlap with free email outreach tools for early testing.

Why We Built 360Airo
