1. Mailcatcher
Effortless Email Testing for Your Projects
Mailcatcher is a hosted software that catches emails before they reach your users, so you can test with real emails and real customers without them noticing. It shows you the email how it would have been sent, with the Text Content, rendered HTML Preview, all Headers and Attachments. All of that in a Web Interface that allows for fine grained user control so you can share projects with co-workers and customers alike.
2. Void Relay
The email Api for your own smtp provider
I built Relay Beta for developers who want real control and real scale. You bring your own SMTP server, I provide a fast edge-native Email API with per-server API keys, robust webhooks, and delivery metrics. The goal is simple: lower costs, fewer limits, and zero vendor lock-in. This is the very first, very fast version—we’re in Beta, and every bit of feedback matters. Early adopters will shape features, security refinements, and performance tweaks as we iterate.
3. Datacrecy
Stop paying to verify leads you already paid for
Datacrecy provides access to 2.5 billion pre-verified B2B contacts. It is the world's largest verified B2B2C lead database. Every email is SMTP-validated before download, removing the cost and need for a separate verifier. Scrape LinkedIn accountless with zero ban risk, target buyers with deep enrichment filters, and download clean, ready-to-use contacts at the lowest per-lead cost in the market. Start for free and stop buying leads twice.
