Problem
B2B startups and agencies often struggle to ensure their outreach emails consistently reach the primary inbox, as opposed to spam folders, due to black-box algorithms and deliverability issues with standard email services. Sending outreach emails through the same system as internal communications can negatively impact the domain reputation, leading to important emails being marked as spam.
Solution
Lightmeter provides a managed email delivery network designed to ensure outreach emails reach the intended recipients' inboxes, independent of Google, Microsoft, or SendGrid. The platform isolates sales email traffic from office email accounts, protecting the overall domain reputation and preventing important communications from being flagged as spam. Lightmeter's proprietary mail server technology checks, cleans, and finds the optimal route for each email, providing users with analytics and automated performance testing to monitor deliverability. The system integrates with existing sales tools, such as Apollo, Instantly.ai, and Outreach.io, without requiring changes to established workflows.
Target Audience
Lightmeter primarily targets B2B startups, marketplaces, and GTM agencies that require reliable and scalable email outreach to generate leads and drive sales.
