Email Gateway Compression Software

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!
— Jennifer Mahoney, COO Heffernan Group

Key features

Any SMTP Environment

Optemail is a 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.


Requires no change to users’ workflows and no downtime. It simply runs in the background automatically reducing the size of emails before they hit the server.

Weekly Reports

Receive comprehensive reports of the savings from compressing your users’ email attachments.

“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”
— Andrew Grainger, IT Database Development Officer, The Royal College of Veterinary Sugeons
