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 had the pleasure of working with Milan and his agency for telemarketing services for my Christmas light installation business, and I couldn't be more satisfied. They were punctual, precise, and incredibly well-organized. Milan was my main point of contact, and he ensured that every request was met with professionalism and efficiency. The quality of leads generated was impressive, and the entire experience was seamless. I highly recommend this agency for anyone looking for reliable and effective telemarketing services.

Johnson Legal PLLC Review from Google
1.0★
Johnson Legal PLLC's Review Sourced from Google
As a small law office, we used AnswerFirst for about a year. We opted not to have calls recorded as their system has an irritating "beep" that sounds in the background while customers are on the phone. We thought things were going well. Several months later we signed up for CallRail, which recorded all incoming calls. We began to see a pattern of poorly handled calls. When we shared this information with management, and offered to provide the recording, they said "no thanks." The probems continued. For instance one caller asked if we did simple Wills. The AnswerFirst agent said, "No, we only do Estate Planning." After sharing these simple issues with management nothing changed. We asked if they could give us an adjustment to our bill based on the poorly handled responses. They said "No." We notified them this week we were switching carriers and they acted like they could care less. DO NOT use them as they cannot handle the simplest of calls.

Outstanding After-Hours Answering Service – Highly Recommend for Service-Based BusinessesWe've transitioned to AnswerFirst about four months ago for our after-hours answering service needs, and they’ve exceeded every expectation. Their live agent support, combined with responsive customer service and advanced technology integration, has provided our team with a seamless and professional solution that far surpasses our previous provider.What sets AnswerFirst apart is their adaptability to our unique workflows, quick response times, and overall attention to detail. As a service business, having a reliable, U.S.-based call center is essential and AnswerFirst delivers with consistency and clarity.Their platform gives us the functionality we need, and the quality of their after-hours call handling has significantly improved both our internal efficiency and our customer experience.If you're a service-based company looking for high-quality live agents, professional support, and a partner who understands urgency and accountability, I highly recommend AnswerFirst. Exceptional value, exceptional team.Demetri KaroutsosDirector, CareMaster

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.
