Digital Marketing Review from Michael Fratangelo
We had a great experience with Pearl Lemon. Our account manager, Dimple was quick to respond to my enquiry and provide a quote and timeframe for delivery of HTML coded emails. The price was really reasonable and they actually delivered the template ahead of schedule! We also had some feedback on the final product which they rectified promptly and free of charge.
