Cold Email Deliverability Checkup

Catch bounce risk before small businesses send B2B cold email

Problem

Small business owners doing B2B outreach find raw exports full of catch-all and outdated addresses, pushing bounce rates past 5% and damaging domain reputation fast. They manually clean lists down to about 1%, a painful and non-repeatable process.

Solution

A list checkup tool for non-technical small teams: upload a CSV, and it flags syntax errors, disposable domains, catch-all risk and stale signals, returns a bounce-risk score with cleaning suggestions, and warns on domain reputation issues. No giant database, just risk tiering.

Users

1–20 person small businesses doing their own outreach, solo salespeople, agencies

MVP

CSV upload and dedupe; syntax/disposable/role-address detection; catch-all domain risk flags; bounce-risk tiers and export; quick domain blacklist self-check

Revenue

Pay per list size (first 500 rows free, then usage-based) or monthly subscription with a fixed quota

Why now

B2B cold outreach is widespread among small businesses while enterprise data-hygiene tools are too pricey and complex; rules plus a light validation API are enough for an indie MVP
