STOA's Verdict

5.5

Rating

Resend is best for small businesses that have a developer on their team and need a clean, reliable way to send automated emails like receipts, password resets, or newsletters. The free plan covers 3,000 emails per month, and paid plans start at $20/month, which is fair for what you get. The big catch is that this tool requires coding knowledge — if you don't have a developer, you'll struggle to set it up and get value from it.
