About this Startup

InboxReady is an email deliverability monitoring and warm-up platform for B2B sales teams, marketing agencies, and SaaS companies. It monitors SPF/DKIM/DMARC health, seed-tests campaigns before send, and runs automated inbox warm-up sequences for new sending domains.

About the Product

What is the SaaS?

A deliverability intelligence SaaS that sits between your ESP and your campaign sends — checking infrastructure health, simulating inbox placement across major mail providers, and automating the warm-up of new domains/IPs.

Problems it Solves

Cold outreach domains hitting spam folders; marketing campaigns with mysteriously low open rates caused by deliverability issues rather than content; teams spinning up new domains with no warm-up strategy.

MOAT & Differentiators

Proprietary seed inbox network across 40+ mail providers and ISPs; real-time blacklist monitoring across 90 lists; domain reputation scoring with root-cause diagnostics rather than just alerts; agency multi-client dashboard with white-label reporting.
