"A signature management tool that works faultlessly"

Prior to discovering Exclaimer Cloud, our small business was using homemade templates in Microsoft365 which failed to produce the results we wanted across the range of devices our customers were using. After we made the switch to outsourcing, we have been delighted with the consistent results our customers experience, particularly as our signature includes a compliance statement that needs to be readily visible to all recipients.

"Decent email signature manager with great flexibility"

Our company basically has 4 separate business units that need to appear "somewhat" cohesive while also still remaining separate and free to create their own email signatures. Exclaimer allows for a dedicated set of managers at each business unit to admin the users for that business unit, while also being able to duplicate/copy/modify signatures from other business units to allow for more cohesive brand styling between our business units and the parent company.

"Excellent service, takes all the hassle out of Office 365 Signatures!"

Simple pricing shown on their website rather than having to request a quote. Simple to set up with automated systems to configure your account and Office 365, linking the two together without having to know anything technical! Simple to use, all through an online WYSIWYG editor.

"Auto organisational signatures, bye bye messy signatures"

The integration with Office 365 is excellent. The template editor lets you have different signatures for different users, departments or groups. You can change the email signatures templates for individual members, groups or the entire organisation. The changes take effect immediately. Using Exclaimer means that staff no longer need to worry about setting up individual signatures.

"Professional signatures, very versatile"

The features I most use are the signature tester and troubleshooters, which can help you to determine what signature a particular user will get when sending to certain recipients. You can have separate internal and external signatures or even change your signature details by recipient domain, so if you have a partner organisation that you're happy to share your mobile number with, but wouldn't give that out to the public, you can do that.
