Lightmeter

Lightmeter is a sales-focused email deliverability company that helps businesses run scalable, sustainable outreach without putting everyday business email at risk. Independent of Google, Microsoft, and SendGrid, its delivery network runs on Lightmeter’s own mailserver product and separates sales sending from office communications. The company combines managed expertise with proprietary AI and a platform designed to improve inbox placement and support reliable sales performance.

Lightmeter serves B2B startups, digital marketplaces, and go-to-market agencies. Its service includes domain and mailbox warmup, address validation, automated inbox-placement testing, delivery analytics, performance alerts, and expert support. Backup domains and mailboxes can be prepared as replacements to help reduce disruption. The network checks and cleans messages, selects a delivery route, and reports results through its analytics interface, giving teams visibility into where emails land and how campaigns perform.

Lightmeter says customers can begin sending within seven days, with capacity of up to 7,500 emails daily. The company also offers agency-oriented oversight, analytics, and control, helping sales teams scale outreach while protecting their core work email.
