      PPC Review from Ahmed Iqbal Khan

      Espial worked for us to deliver quality leads through PPC campaigns. Our challenge was that we hardly had 1% conversion from all the clicks that we were getting through Google Adwords. Within a month our lead to conversion increased from 1% to 5%, that was a remarkable achievement. They know which design and content works best. The level of communication and responsiveness that we receive from them makes them incredibly easy to work with.

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.
