Exclaimer was really easy to setup, and it not only works on Outlook Desktop but also on Mobile, and Web, which made us select exclaimer. Features such as seperate signature for reply is really helpful as well. Customer support is helpful and respoonsive. Easily integrates with Microsoft Entra ID so it was really easy provisioning users. I use it for work daily and has been using since the last 4 years.

Easy to deploy signatures to specific groups

I love the ability to make changes to everyones signature at once without needing employees to lift a finger. I also really love the campaign banner features.
