I’ve been working with Lulu for over a year now and couldn’t be happier with the Mailbox Power platform that I use for O’Donnell Roofing Co. It allows us to deliver personal direct mail experiences to our customers and employees, while also helping us target certain neighborhoods. It’s so easy to use and gives you a decent amount of options to choose from. I highly recommend this tool for any business who wants to upgrade their customer experience.

I absolutely love Mailbox Power! Having birthday and home anniversary cards on automation saves me so much time! Even thank you cards are made easier - I don’t have to go to the store for cards, buy stamps, or mail them! Automations are really easy to set up for different marketing strategies as well! Thank you Lulu for introducing me to Mailbox Power!
