Built on Real Email Infrastructure

Not an API wrapper. Not shared ESPs.

Inwren runs its own email infrastructure—from MTA and SMTP to bounce handling, analytics, and reputation management—so your emails land in the inbox, not the spam folder.

Dedicated Sending, Done Right

Your domain. Your IP. Your reputation.

  • Custom-built MTA & SMTP stack operated by Inwren
  • Dedicated domains & IP addresses for Pro customers
  • Full control over SPF, DKIM, DMARC, and rDNS
  • Zero reputation leakage from shared senders

Inbox-First Deliverability Engine

Engineered for inbox placement—not bulk volume.

  • Automated IP & domain warm-up
  • Intelligent throttling by mailbox provider
  • Advanced bounce classification
  • Feedback-hover driven suppression

Built-In Email Verification

Know before you send.

  • Invalid and non-existent mailboxes
  • Catch-all / accept-all domains
  • Disposable and role-based addresses
  • Domain and MX misconfigurations

AI-Assisted Confidence Scoring

Each address is evaluated using multiple intelligence signals. You decide who to send, pause, or review before damage happens.
