Callbox Client feedback - Terrie Cheung

Under the COVID-19 situation, while our sales team and most of our prospects are forced to work from home in Hong Kong, the Callbox team managed to keep us busy through these turbulent times, by connecting our prospects over phone, set-up online appointments and online demo for our sales team. We are very thankful to have Callbox as our extended marketing team, and helping us to connect with high-quality prospects.

Callbox Client feedback - 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.

Callbox Client feedback - Joel Golub

I have found Callbox to be a relatively inexpensive way to generate leads. I have only been using them for a few months but so far I am getting reach into markets that I would not have the time to develop ourselves. Great for opening up a new vertical.

Callbox Client feedback - 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.

Callbox Client feedback - 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.

Callbox Client feedback - Kevin Ramsey

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.

Callbox Client feedback - Vanessa Errington

I have been using Callbox for 5 months now to help me promote our corporate education program. They have been securing face to face meetings with HR Departments so that I can explain our wellness initiatives and offer complimentary talks and screenings. They are professional and courteous on the telephone and the clients I have visited have only ever been complimentary about the team when I have asked them. I am enjoying working with them.

Callbox Client feedback - Eugene Alfaro

I am very impressed with the business that Callbox has become. Marcus Lemonis, a billionaire entrepreneur in the US who builds up businesses, tells companies that the key to a successful business is to have the right people, a well-defined process, and a quality product. In the case of Callbox, you have very good people that can be successful because of a very well-designed process which results in a quality product for your clients.

Callbox Client feedback - Adam Welchman

Our business has been working with Callbox for over four years. We have an efficient internal team and software which allows us to operate a lean workforce. So, we wear many hats. Callbox has been a good decision for us due to the high return in our industry and the ease of working with them. I’ve had the same representative for at least the last 3 out of 4 years. Ms. Figueroa is always attentive and their technical team has always found ways to address my concerns.

Adam Welchman

Callbox Client feedback - Jon Thompson

Great experience with them. Of course, I only know my team, but the account management has been excellent, and they have exceeded my expectations in terms of # of appointments. Very open to my input on script, changing callers, etc. One of the best service-provider experiences I’ve ever had. This is my 4th attempt at using an appointment setting service, and this is the only one that has succeeded.

I just wanted to take this opportunity to express my great appreciation for the efforts of Melisa Torres, she has always gone above and beyond for my partner John and myself. She is continuously striving to improve our campaign success by offering suggestions and making adjustments to assure that our needs are accommodated in a timely manner. Callbox is very lucky to have not only an employee but an asset of Melisa’s stature and ability. We are also very lucky to have her as our project manager.

Callbox Client feedback - Raymond Britt

We agreed to continue our campaign with Callbox because we are seeing improvement of the calls. We like the contact we have with Melanie, Mae, Aubrey and Caren and we really see that the communication we have works in a positive way. We see that Caren is taking note of all the feedback we give and this causes better appointments. We are looking forward to further improve the next 5 weeks and have all the demo’s attend! Keep up the good work.

Callbox Client feedback - Carolyn Miyazaki

I am pleased to recommend Bernadette and the company Callbox. They have consistently worked with a collaborative attitude to ensure all processes are current and achieve all set key performance indicators. Whenever an issue did arise we worked through the issue in a timely and efficient manner so goals remained on target. They have a positive, easy to work with demeanor and strive to exceed performance expectations. I highly recommend their services.

Callbox Client feedback - Ron Rogers

Callbox has done an excellent job for us, we have closed their leads and have several more in the pipeline. Many of these new leads were some we did not have in our database. So their list is worthwhile too. Expect the first month be used to fine tune the call list. We had trouble with this. We were somewhat inexperienced choosing the correct SIC codes. I also listened to someone else and lowered the minimum revenue number; disaster. They are effective so make sure they are calling the people in your wheelhouse or you will be smothered with leads you don’t want. We gave them a script to capture information important to us so we could determine easily the value of the lead.

Callbox Client feedback - Larry Adler

I just wanted to write to you guys to say what a pleasure it has been working with you on our outbound lead generation campaigns in Singapore. The professionalism in the setup and execution was second to none. You opened up a number of opportunities that we are now capitalizing on. Well done and thanks!

Callbox Client feedback - Geoffrey Wade

I just wanted to write another short thank you note. You are doing good work for us which is building into a healthy new pipeline. Each day I look forward to those e-mails you send which start “New Lead From Callbox” They all put a smile on my dial! Thank you for your efforts on our behalf, and thank you for the results which continue to meet or exceed our targets.

Geoffrey Wade

Callbox Client feedback - Mike Stout

I have been very pleased with your results and Callbox has exceeded my expectations. While 22 appointments to date may not seem a lot, I am happy with these results which have led to follow up in-person meetings by several of our team members.

Callbox Client feedback - Anton Vdovin

I would like to write about our experience with your telemarketing campaign. From the planning and preparation stage, it was obvious that your services were focused on quality, not quantity. Your initial advice in relation to the target market, call list, and the script allowed us to narrow down the range of prospects and generate initial interest in our services from the exact type of business clients that we were looking for. After I attended the initial appointments, you offered a review to sharpen the strategy to better qualify the prospects. As a result, thereafter 100% of appointments were from our desired target group. One of the appointments created 3 opportunities, of which 2 have been converted. I believe your initial advice and ongoing support made it a success. I also found the campaign reporting easy to comprehend and very helpful in evaluating the strategy and results. Thank you for recommending the campaign and I would like to discuss with you using it again later in the year. Also, I will have no hesitation in recommending your telemarketing services to my business contacts and friends.
