Cold Email Deliverability Precheck

Verifies email validity, role, and domain risk before cold sends

Problem

SaaS founders report that bounce rates and generic inbox pollution (support@, sales@, disposable domains) damage sender reputation, and they need verification before sending or importing into CRM. Current workflows lack decision-maker filtering and batch validation.

Solution

A microservice or browser extension that batch-verifies email addresses: checks syntax, domain validity, disposable domains, role-based inboxes (e.g., support@), and can keep only decision-maker inboxes; provides API for pre-CRM import filtering to reduce bounces.

Users

SaaS founders doing cold outreach, sales development reps, and growth marketers.

MVP

Batch verify up to 100 emails per call; filter disposable domains and role inboxes; flag high-risk emails with reasons; provide API and CSV export; simple dashboard showing verification history.

Revenue

Pay-per-verification (e.g., $5 per 1,000) or $19/month subscription with API access.

Why now

Cold email remains a key SaaS acquisition channel, but sender reputation management is harder; indie developers can quickly build a lightweight verification layer that plugs into existing tools.
