Frequently Asked Questions
What is Lightmeter used for?
Lightmeter is used to send sales outreach email through a separate, managed delivery network so messages reach the inbox and the company's regular work email stays protected.
Who is Lightmeter for?
It is built for B2B startups and scale-ups, B2B marketplaces scaling both sides of their market, and GTM agencies that need oversight and reporting across client sending.
How does Lightmeter protect deliverability?
It warms up domains and mailboxes, validates addresses before sending, keeps backup mailboxes warmed in case of problems, and runs daily inbox placement tests for each mailbox.
Does Lightmeter replace Google Workspace for outreach?
Yes. Outreach email is sent through Lightmeter's own servers instead of Google, Microsoft or SendGrid, which isolates sales sending from the rest of the company's email.
