Lightmeter
Turn-key outreach infrastructure with managed email deliverability
Lightmeter is a sales-only email delivery network that separates outreach sending from office email, using its own mailserver product rather than Google, Microsoft or SendGrid. It is designed to keep sales campaigns out of spam while protecting work mail from suspension or deliverability problems, and to give teams more control over how outreach is routed and monitored.
The platform includes warmup with GenAI, an outreach delivery network, backup domains and mailboxes for disruption prevention, automated daily inbox placement testing, address validation before delivery, and an analytics platform with trends, alerts, customisation and data export. Delivery routes are checked and cleaned before sending, with results reported in the analytics interface. The service is aimed at B2B startups, marketplaces and GTM agencies, with agency-specific oversight and tooling. Onboarding is described as taking seven days, with express warmup supporting up to 7,500 emails daily.
