๐Ÿš€ Stop Wasting Send Credits: Meet TrueMailer

(Email Validation That Actually Ships)

If youโ€™re onboarding users, running campaigns, or fighting fake signups, bad emails quietly burn cash and wreck deliverability.
TrueMailer fixes that โ€” with a fast, privacy-first email validation API your team can plug in within minutes.

โšก Why It Matters

๐Ÿ’Œ Protect Deliverability โ€” Keep your sender reputation clean and your messages out of spam.
๐Ÿงน Cut Fraud and Noise โ€” Catch throwaways and role-based aliases at the gate.
๐Ÿ’ฐ Save Money โ€” Stop paying to send to bad addresses; clean lists before campaigns.
โš™๏ธ Move Faster โ€” Simple REST API, clear JSON, real-time results.

๐Ÿง  What TrueMailer Checks

  • โœ… Syntax Validity: RFC-style formatting checks
  • ๐Ÿšซ Disposable / Temporary Domains: Detects 10MinuteMail, TempMail, GuerrillaMail, etc.
  • ๐Ÿ‘ฅ Role-Based Aliases: Filters admin@, info@, support@ and other non-personal addresses
  • ๐ŸŒ MX Records: Confirms whether a domain can actually receive mail
  • ๐ŸŽฏ Risk Scoring: With confidence levels for decision-making
  • ๐Ÿงพ Allowlist Signals: Recognizes trusted and verified domains
  • ๐Ÿ›ก๏ธ Personal Overrides: Custom allow/block rules per team

๐Ÿ‘ฅ Who Itโ€™s For

Growth, Marketing, Ops Teams:
โ†’ Fewer bounces, better segmentation, cleaner analytics, and happier CRMs.

Product & Platform Teams:
โ†’ Prevent junk signups, improve marketplace trust, and reduce moderation load.

Developers:
โ†’ A single POST request gives you everything you need to decide โ€œlet in or challenge.โ€
