Best fit
Who each tool is for
Apollo
Strong ChoiceBest for: Independent consultants testing outbound for the first time — free tier covers real campaigns.
Why pick it: The largest B2B contact database available at this price point, with a genuinely useful free tier. You can go from zero to sending outreach in 30 minutes.
Watch for: If you already have a lead source (referrals, inbound), the database is wasted. Use a lighter outreach tool instead.
C
cold0
ConditionalBest for: Developers who want to learn cold email infrastructure from the ground up.
Why pick it: Truly free, no usage limits. Good if you want to learn how cold email infrastructure works from the ground up.
Watch for: Single-developer project with no support. Not production-ready for serious outbound — use a hosted platform instead.
