Review My Emails

Review My Emails is an email list cleaning and validation service for senders of every kind and every size. It does everything a validator does, checking whether an address exists and can receive mail, then goes further to answer the question that matters: is it safe to send to? Every address comes back with a verdict, keep, monitor or suppress, a plain-English label explaining why, and a recommended action. The labels catch things a syntax check never will. You buy credits, upload your list, and get your validated results back, or use the done-for-you service. Founded in 2020 by Yanna-Torry Aspraki, Bruno S Brasil and Diego Silva, with a team across Europe, the Americas and Asia.

Safilist

Safilist is an email verification service that shows you exactly what was checked and why behind every result — not just a pass/fail grade. Upload a list or check a single address, and Safilist runs full syntax, MX, SMTP, catch-all, role-account and disposable-domain checks, then returns a clear status (Safe, Risky, or Invalid), a confidence score, and a plain-language recommendation for each email. Where other tools discard everything "risky," Safilist surfaces the addresses that are actually deliverable — so you keep leads competitors would throw away. Results export cleanly to CSV or push straight into your email platform. Built for marketers, sales teams, and developers who want cleaner lists, higher inbox placement, and verification they can actually understand. Your data is never sold, shared, or monetized — it's company policy.
