Contact and customer databse with bulk email facility

We facilitate via our website, home dog boarding, so we will have an expanding Boarder, customer and geographic data set. in addition, there will be regulatory authorities (Councils), licenses and all things associated with renewal, application and fees etc. We need a one time database, we can buy and start using in the Microsoft family, that can help filter, remind, task, bulk email, track and follow-up. Think Air BnB for dogs and how that runs and that may help.
