It just works, fairly easy editor. Lots of customizing options, however it also works without optimizing. Quality of support is great. They helped me perfectly with migration of some signatures

I love that I can easily create different signatures for different teams. I like that I can track interactions with the signatures and that I can add new links with ease. I like the campaign feature where I can add a new item to all signatures for a short time rather than editing each signature type I have! We recently had a great conversation with customer support staff that allowed us to feel like our adoption of the product was leading us on the right path. We do use this all the time, I change the signatures once a quarter and include specific campaign details often, so I would say we see the value in Exclaimer.

I have been using Exclaimer now for years for our M365 clients and it is an excellent service and can never fault their service, template options and ease of managment. integration is a snap and the advanced reporting is wonderful for clients as well.
