Hugo Reviews & Testimonials
B2B Review from Greg Digneo
Best decision we made last year was partnering with this CX team for our customer support, billing, and sales assistance. We were drowning in client emails and chasing invoices late at night instead of focusing on SEO strategy. Results have been incredible: client response times dropped from hours to under an hour, payment collection improved 60%, landing page conversions up 28%, and client retention increased 35%. They integrated seamlessly with our systems and scaled with us as we grew. Now we have more time to focus on delivering SEO results instead of being stuck in support tickets all day. If you're an agency juggling client support with campaign management, this team is a game-changer.
BPO Review from Nimmit Shah
Collaborating with Hugo elevated our property management firm's performance. Their support solutions slashed response times by 40% and boosted tenant satisfaction by 30%. Hugo's seamless integration proved instrumental in propelling our business forward, setting new benchmarks in operational excellence.
Customer Support Review from Jambu Subramanian
Their team quickly integrated into our workflow, demonstrating a deep understanding of our business needs. We were impressed by their professionalism and the ease with which they handled complex customer inquiries. Hugo's technical support team showed exceptional problem-solving skills, significantly reducing resolution times for order issues.

Vserve Ebusiness Solutions Reviews & Testimonials
Customer Support Review from Marie M. Harris
Although we have been struggling before, after expanding our influence into mountain wear and watches, it became evident that we needed some professional help. We were offering many new products, and making matters worse, we were present in different foreign markets, which mean many competitors to keep an eye on. After some consultations with the Vserve team, we had no doubts that they were the solution we had been looking for. Thanks to their proven MAP enforcement strategies, maintaining our market position is now easier. We always have accurate pricing information at our fingerprints. I must say, we are really impressed with Vserve.
Customer Support Review from Danielle W
Our company is grateful to have found a collaborative team in Vserve for our Product Information Management. Initially, we were unsure about the quality of product descriptions and their accessibility to our buyers. However, Vserve’s expertise in programming language and business best practices helped us to manage our complete product information and catalog pretty well. The conversion rate excelled our expectations, and our products shot up on Google rankings!

Everything you need to know before hiring a telemarketing company
How can a B2B telemarketing agency help my business?
B2B telemarketing agencies are commonly sought to maximize cold outreach and deliver qualified leads.
Gartner found that 73% of B2B buyers actively avoid suppliers that send irrelevant outreach, so a professional telemarketing agency can help you avoid wasting interactions and damaging first impressions.
Capacity is another reason to outsource.
Notably, 47% of sales reps say their team lacks the bandwidth to do cold outreach, and a specialized agency can fill that gap.
A telemarketing company also brings trained callers, tested scripts, call quality control, and regular follow-up, allowing you to speed up your sales cycle without stretching your internal team.
Some B2B sales can take months to close, often because leads lose interest before your team can follow up.
In that regard, a specialized agency can deliver the consistency to keep prospects engaged, follow up at the right intervals, answer objections, and keep your brand top of mind.
Can a telemarketing company help me reach decision-makers faster?
Yes, telemarketing companies can help you reach decision-makers faster as they dedicate a team that will fully focus on outreach.
Research shows that phone outreach still works best at senior level.
As 57% of C-level and VP-level buyers prefer the phone to discuss deals, a telemarketing agency has a better chance of getting in touch with leadership than an email-only approach.
Considering it takes an average of 8 interactions to schedule a meeting, agencies can extend the capacity to keep that cadence going without leads going cold between attempts.
How do telemarketing agencies maximize campaign performance?
Telemarketing companies do script revisions and strategy adjustments to optimize campaign performance.
They review call recordings, conversion metrics, and agent feedback to identify what’s working and what needs improvement.
Based on these insights, telemarketing firms update scripts, refine targeting, and adjust follow-up workflows to improve outcomes.
Most agencies revisit strategy on a monthly basis to make sure the campaign resonates with customer responses and market conditions.
How can I find a telemarketing agency on DesignRush that fits my budget?
We compiled a list of telemarketing companies across different price points to help you find a specialist that’s within your budget limitations.
| High budget: $50,000+ |
|
| Low budget: $25,000 to $50,000 |
|
Beyond budget, our directory allows you to filter agencies by hourly rate, service type, location, reviews, team size, and more.
What questions should I ask these specialists during the interview?
You should ask some of the following questions to make sure the candidate is a good fit for the project:
Relevant Background
- Have you worked with companies operating in a similar sector to ours? What results did you achieve?
- Can you share recent examples of successful campaigns?
- How experienced are your callers in speaking with senior decision-makers?
- What kind of training and onboarding do your agents go through before working on a campaign?
Services and Processes
- How do you create and refine call scripts for different campaigns?
- Can you walk me through your lead qualification process?
- How frequently do you do follow-ups and multi-touch outreach sequences?
- How do you monitor call quality and maintain consistency across agents?
- What metrics do you track to measure campaign performance?
Related to Your Project
- How often will we receive reporting and performance updates?
- How would you approach our specific ideal customer profile?
- How quickly can we start the campaign?
- What results should we realistically expect in the first 30 days?
- What challenges do you anticipate with our project?
- What level of involvement will you need from our team during the campaign?
Sources
DesignRush sustains a directory of over 40,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:
- Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
- The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.
Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.

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.
