Best fit
Who each tool is for
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.
Gumroad
Strong ChoiceBest for: Consultants productizing their expertise into sellable templates, frameworks, and digital downloads.
Why pick it: Zero monthly fee removes the risk of launching a product. 10% per sale means you only pay when you earn. Setup takes minutes, not days.
Watch for: The 10% fee adds up at scale. If you sell more than $5K/month in digital products, a platform with flat monthly pricing (like Teachable or Kajabi) is more cost-effective.
