Callbox Reviews & Testimonials

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.

Martal Group Reviews & Testimonials

Marketing Review from Nidhi Jaiswal
From the very start, their team was very professional, communicated in a timely manner, and was very familiar with B2B lead generation. We were just surprised at their team culture and their desire to work hand-in-hand with our team. It felt like they were not an external vendor but a true partner in all respects.Throughout our working time together, Martal always produced excellent work while keeping us informed and engaged. They are solution-oriented, proactive, and willing to share ideas that enhance performance. It is not often that you find a team that is so concerned about your success.What we value most is their honesty and commitment to building something that will last. They don't seek quick wins but work to build outcomes that last and can potentially expand. With their experience combined with a well-structured plan, they are a reliable and outcome-driven collaborator.If you need to reach more customers and you would like to have a company that is concerned about your success, you can rely on Martal Group. We highly recommend that you use their services.

Customer Support Review from Maria Maidana
Helpware has been a trusted partner for SquadLocker for several years now for customer success. Our Customer Onboarding Team continues to shine through every administrator that interacts via our Live Chat channel for store help. Anzhelika is my Onboarding Lead and we work hand in hand in making any and all decisions for team enhancements. She delights both DIY and Enterprise administrators across multiple channels here at SquadLocker. I would not be as successful without Anzhelika by my side. I forsee using Helpware for years to come!

mia trigo's Review Sourced from Google
requires a star but actually my rating to this company is negative stars lol. This company is a scam. They act like their interviewing and offer a position then they ask for money in form of a gift card. Be careful this is a scam. No company would ask for you to pay them to work for them. I wasted 3 hours with this company in hopes of a job. All they did was waste my time.

Anjali Nawal's Review Sourced from Google
Starting my internship with Protovo by my first year of engineering and becoming the junior software engineer at Protovo, it was really a great experience and time with a company like this where i got to know about many of the latest technologies and one with great work culture which every person dream for. A great boss is always a one people want in company and here I got three. Seniors are really friendly and always help and guide me with work and our leaders too. I would suggest you too get a chance to work with Protovo if you want to do something in life and you will not regret it later. Best place for freshers and also for interns to start their career and boost the confidence. Go with Protovo #protovian

Briana B's Review Sourced from Google
Spams via email but also somehow got a hold of my phone number. They call every single day and leave a long message that I cannot understand because of the accent. How is annoying your potential clients to death a viable business model? Go away. Ignoring you 40 times CLEARLY means I'm not interested.

They conducted my L1 interview twice, and I attempted all the questions. However, they accused me of using ChatGPT to answer them. I even rotated my camera to show my surroundings and prove that I wasn't getting any assistance. After that, I received no feedback from them."
Prateek S chowdhary's Review Sourced from Google
if there is a possibility of giving minus 5 star i will give that,CHEATERS is the only word for them , they will keep your goods and will ask to pay 3 months extra after that, don't fall into their TRAP. i am taking them to consumer court for the things which they have done.

5 Frequently Asked Questions About Telemarketing Firms
What do telemarketing companies do?
Telemarketing agencies use phone-based direct marketing to sell products, generate leads, or book appointments on behalf of businesses, performing both outbound and inbound calls to grow sales pipelines and client relationships.
As all telemarketing interactions involve direct human contact, the approach allows them to influence potential customers’ opinions, purchasing habits, or perceptions toward a brand.
What services do telemarketing firms provide?
Telemarketing services for businesses can be split into two main categories: inbound and outbound.
- Inbound telemarketing services cover customer support calls, namely technical support, order taking, billing inquiries, upselling, and virtual receptionist service, to name a few. They can support both B2B and B2C companies.
- Outbound telemarketing services, also referred to as proactive outreach, are intended to boost businesses’ bottom line. This category comprises several different service types, including lead qualification, appointment setting, cold calling, customer reactivation, and more.
B2B telemarketing companies are often hired to assist non-profit organizations in soliciting donations or to collect debt and follow up on overdue accounts on behalf of other businesses.
How much do telemarketing agencies charge for their services?
Telemarketing agencies charge between $7 and $75 per hour for their services. The service cost can also vary based on location (offshore vs. onshore), campaign complexity, duration, and agent experience, with B2B telemarketing campaigns often costing more than B2C.
Other common pricing models include:
- Per-lead: $35 to $60 per qualified lead
- Flat-rate: $650+ for a 4-week campaign
- Commission-based: 5% to 20% of each closed sale
How long do telemarketing campaigns take?
Telemarketing campaigns usually take a few months, as lead nurturing takes multiple phone calls for telemarketers to engage with a prospect and close a sale.
Although initial lead generation begins within the first few weeks, for a full, effective cycle, the campaigns are run between 3 and 6 months. The average campaign takes about 14 weeks to reach an optimum level of opportunities per day. The length also depends on the campaign type:
- Pilot and trial campaigns: Usually run for 10 to 12 weeks to test the market, refine the pitch, and validate traction.
- Short campaigns: 4 to 6 weeks for time-sensitive promotions or event registrations.
- Long-term campaigns: 6 months to over a year for slow B2B sales cycles that require more lead nurturing.
What kind of ROI can businesses expect from telemarketing campaigns?
Lucrative telemarketing campaigns often result in a 5:1 to 10:1 return on investment (ROI), meaning $5 to $10 in revenue for every $1 spent. The return rate depends on the quality of the call lists, the persuasion skill of the callers, the product, the offer, and whether it's part of a multi-channel strategy. Notably, ROI grows over time through stronger customer retention and better targeting informed by feedback from calls.
