Niche FitBest for: Technically comfortable consultants who want minimal OSS outreach tools.
Why pick it: Lightweight open-source bulk sender. SMTP + CSV, basic tracking. For consultants who prefer building over buying.

Why pick it: Largest app ecosystem (9,000+). The free tier covers 100 tasks/month — enough for most solo consultants. No coding required, and the built-in Copilot can build a workflow from a plain-English description.
