Key Features

any SMTP environment

Optemail is a versatile software-only solution that works with any email environment. It can be hosted in-house on either a physical or virtual server, or you can choose to let us securely host if for you.



Optemail requires no changes to users' existing workflows and no downtime. Once started it simply runs in the background automatically reducing the size of emails before they hit the server.

We are really happy with the savings Optemail gives us. Our weekly reports show savings of around 35-40% of storage and bandwidth reclaimed from incoming and outgoing mail. 25.2 GB > 15.4 GB . It really takes a weight off our mind

We’ve been running Optemail for the last 6 months, and we’ve realized a 38% reduction in email traffic and storage! As an insurance brokerage with 400+ employees, we couldn’t be happier about the current and future cost savings this means for us. It’s a fantastic tool!
