Instant overview

Of Mail Delivery

Mail matters but getting mail reliably and quickly in the inbox of recipients is hard. Lightmeter shows you where the bottlenecks are so you don't waste time searching for the problem.

100% on premise

And Under Your Control

When a mail does not arrive, you have a problem. Lightmeter's smart algorithms know when a problem is temporary or structural and warns you if you have to take action. Don't wait for users to complain!

Unique depth of insight
