      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.

      Call Centers Review from Eric Martin

      The salesman, Luke?, was very responsive and knowledgeable, a true professional. On boarding with Bailey, was easy and very thorough. Getting on board with an answering service had a lot more detail than I expected and Bailey was very patient and did not rush the process.

      I needed to get two new numbers set up quickly and Marti Ramirez was able to immediately help me out immediately. Also, Marti had some great suggestions for the scripting that was greatly appreciated. He even went above and beyond to check my multiple other accounts to make sure everything was OK with them. Marti is definitely an employee that goes above and beyond. Thanks again Marti!

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.
