Signatures are often underestimated but they can have legal implications and impact, they can help marketing wise, they should be informative, etc. Most of the email solutions have very limited functionalities in that respect.
iQ.Suite offers centralized multi-language management of signatures - different units, teams, locations and departments can differentiate but yet be in compliance with the company policies. These can be centrally managed by Marketing. For instance, we can have a customized campaign for employees in New York area on a new product – all customer-facing employees in this location would have a reference to the campaign in their signatures for the duration of the campaign.
