MailsGuard

What it does

MailsGuard verifies email addresses via REST API or bulk CSV upload — checking syntax, DNS/MX records, SMTP, disposable emails, catch-all domains, and role-based addresses. $3 per 1,000 verifications. ZeroBounce charges $15. NeverBounce charges $8. Same accuracy, 80% lower cost. Credits never expire. 100 free verifications, no credit card required. Built for developers and marketers who are tired of overpaying for a commodity service.

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
