Lead Generation Review from Joachim Fong
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.
Lead Generation Review from Jonathan Anderson
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.
Appointment Setting Review from Ted Calvin
Charted Energy has enjoyed a productive relationship with Callbox. They have done a great job of helping us target prospects within the markets we serve as well as qualify leads and set up appointments with decision-makers. Callbox has generally exceeded the number of leads per week we expected and provides a good value by enabling our inside sales team.

BPO Review from Debbie Shen
Enshored impressed us by really taking the time to understand our business and what our needs are. We don’t have to do hand-holding in terms of training, which is great! It gives us the freedom to do other things.
a's Review Sourced from Google
I was hired this week for a remote position. I was told I would be getting a company card to make purchases of the software and things needed to perform the job. After I turned in my w4 I noticed there was a hard inquiry on my credit. The person hiring me said that was for the company card. I said I was not comfortable with that. She said it was only for the company card. I then said why can’t I just create an expense report like other companies I’ve worked for? She said that was ok and then asked me my credit limit and offered to pay it off so it can be fully used for work. I agreeed and within minutes there was a payment made by quad city bank to my credit. Becoming more skeptical I reached out to capital one to inquire about the hard inquiry and also the payment made. They verified that enshored tried to open a credit card fully in my name, not attached to the company. The person hiring me keeps trying to convince me this isn’t a scam but when I google this situation, all signs point to scam. Nobody answers the phone at this business and the ceo doesn’t respond on linked in. I asked them to destroy my personal information, I have had no response of confirmation. I also noticed they are not accredited on the better business bureau this is a complete hoax.

Enshored truly sets itself apart from the BPO pack with its core commitment to its team - who ultimately become extensions of your team - and to treating them with great humanity, empathy, and respect across its multiple offices worldwide.
