About Allegrow

Stop losing valid contacts to "unknown" data. Allegrow is the highest quality B2B email verifier built to help data providers & GTM teams increase data quality, prevent bounces, and unlock pipeline hidden behind enterprise and catch-all servers.
Legacy verification tools rely on outdated smtp pings that fail on modern B2B infrastructure. They mark 30% of your list as "unknown", miss hidden spam traps, and fail to validate secure email gateways (segs).
Allegrow is the enterprise-grade solution to this challenge.

- conclusive 'valid'/'invalid' status responses on catch-all domains to safely expand your tam
- verify enterprise mailboxes hidden behind the world’s toughest spam filters
- distinguish the primary
