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.

Call Centers Review from Benjamin Rose
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!

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.

Justine Karren's Review Sourced from Google
Recently signed up with AnswerFirst and couldn't be happier! We've also received nothing but positive feedback from our clients. We also contacted support for the first time and our request was completed within a half-an-hour of creating the ticket.
Karen Mason's Review Sourced from Google
Extremely disappointed. After assuring me that they could pre-qualify callers, they decided that they really couldn't do that and re-wrote the scripts in such a way that I might as well use AI or even a simple voice activated call routing system. They declined even the simplest request: I wanted them to add callbacks to the first available time slot on my schedule -- NOT to schedule the callback time with the client, just to put the message on MY calendar so I would have time carved out to return the call. For some reason that was too hard for them. They did, however, send me messages that were supposedly for me, even though I had never forwarded my lines to them.The response below says they couldn't schedule a callback without the callers permission, which only proves my point that they didn't listen so they didn't get it: all I wanted them to do was add the message to call back to my calendar rather than just taking a message. How is that doing anything without the caller's consent? It was just meant to block time in MY day. Nothing more.If you couldn't qualify callers in your environment, you should have said so when I asked.

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.
