I’ve used Callbox now for about four months for my internet marketing company. The first two months they did not pay off. However with some additional training on my part, they started to close a higher percentage of my target audience. They’re really smart, nice and are really working hard to keep my business. My dedicated team keeps me up-to-date through frequent communications. My R.O.I is getting stronger and my CPA is starting to drop.
Jonathan Anderson
We have been using Callbox for our sales prospecting for the past six months. We have received numerous appointments from the team, which has produced very worthwhile business opportunities for us. I can always reach out to Cris, Eva or Candice if I have a question or concern, and I receive a prompt reply. We truly feel that they are an extension of our company, and we’re very satisfied with our service from Callbox.

For the past year, Callbox has provided us with satisfactory lead generating and lead nurturing services. They were instrumental in securing attendees for our events, scheduling client appointments and facilitating the sale of one of our benchtop systems. Their professionalism in conveying our product attributes and valued solutions to prospective customers has brought us results.
