I like how easy it is for me as an agency owner to manage my team's campaigns (both current & future).
Being in charge of managing all aspects from writing copy/copywriting to designing graphics - we save so much time! The only thing i dislike about this software is its price tag compared to other tools out there which do similar things at lower prices. We've been using Sendero since our inception two years ago now. It has helped us grow tremendously by providing more options than just email blasts or simple content creation platforms.
