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.
Your domain. Your IP. Your reputation.
Engineered for inbox placement—not bulk volume.
Know before you send.
Each address is evaluated using multiple intelligence signals. You decide who to send, pause, or review before damage happens.
| Check | Result | Explanation |
|---|---|---|
| Domain Mail Configuration | Healthy | MX, SPF, DKIM, DMARC present |
| Domain Catch-All Classification | Not Catch-All | Domain explicitly rejects random usernames |
| Username Convention Inference | Match | Domain follows first-name only pattern |
| Inbox Deliverability | Valid | Inbox is reachable |
| Verification Method | Probe | No email sent during verification |
