Best Free AI SDR (2026)

AI-powered tools that automate outbound prospecting. From autonomous AI agents that write and send emails to coaching tools that make human reps sharper.

Free tiers are marketing tools. Some are generous. Most are crippled demos designed to make you upgrade. These rankings cut through the marketing and tell you which free plans are worth using long-term.

The Sultan's Pick for Free Tools: Outplay

Outplay's free plan includes multi-channel outreach across email, phone, LinkedIn, and SMS. You get a full engagement platform at $0, covering more ground than Lavender's email-only coaching. For founders testing outbound channels, Outplay lets you experiment across all of them for free.
