Outsourced SDR Services: 10 Agencies to Rely On

Many studies illustrate how salespeople spend most of their time struggling with prospecting and research instead of actually doing what they do best: having meetings and closing deals. 

In light of this, any service that can eliminate all the banal work salespeople don’t enjoy or struggle doing, and ensure a repeated number of monthly leads so that sales can close more deals can be of unprecedented value for your business. 

That’s where outsourced SDR services come in.

In this article, we will cover the top 10 best outsourced SRD services and how each of them can help your business grow.

What is an outsourced SDR service, and why is it important for lead generation? 

An outsourced SDR (Sales Development Representatives) service is a professional service that specializes in generating and qualifying leads for businesses. 

It involves a dedicated team of sales and lead generation experts who reach out to potential customers on behalf of a company, using various communication channels and outbound lead generation strategies such as cold calling, cold emailing, and social media outreach. 

Outsourcing SDR services can be beneficial for your business as it allows you to leverage the expertise and resources of a specialized team without the overhead costs of hiring and training an in-house team. 

In fact, it is widely regarded as a cost-effective option for companies who need to boost their sales activities but do not have enough resources to pay for the high costs associated with establishing an in-house team of SDRs.

Outsourcing SDR services guarantees you a steady stream of leads and customers while you focus on your core operations. It allows you to leave the lead generation and qualification tasks to the experts. 

As a result, you save time, effort, and resources, and it can result in more effective and efficient lead generation efforts. 

Outsourced SDR services Vs In-house SDR services 

Although there is no right or wrong decision, some circumstances can prompt you to outsource your sales process or lead generation to an SDR outsourcing company. Here are the main reasons it could be a better idea to consider an outsourced SDR company.

1. Experience, expertise, and industry insights

When you outsource your SDRs, you partner with people with a wealth of expertise in lead generation and sales. These are professionals who understand the process and have solved similar pain points for other clients. 

SDR outsourcing companies already know how to acquire leads, the tools to use, find data and understand the sales techniques that work best for your prospects.

Their team of sales reps and lead gen experts can bring industry-specific knowledge and insights, which can be valuable in understanding the target market and creating tailored lead generation and sales strategies.

On the other hand, hiring in-house may not give you these expected results. Since you may have to train them, give them time to learn about the company, and go through a series of trials and errors that could eventually waste your time. In worse situations, they could leave the company, leaving you to start all over again.

But with an outsourced SDR, you don’t have to pay for some repeated processes before you get the expected results. 

2. Cost

Hiring and training an in-house SDR team can be expensive. If your business is new and you don’t know how to generate B2B leads, you may not have enough budget to cater for an in-house SDR yet. 

Or you only have one salesperson and need to bring new employees on board, but you don’t have the budget as well. Before you hire new employees, you need to understand the full cost. 

According to Glassdoor, the average salary for an SDR in the US is $69, 551 per year. Not only do you need to consider the salary, but also the office where they will work, the tools (software and equipment) needed to do their jobs, onboarding and training costs, pensions, holidays, and other benefits. 

Aside from the cost, you also need to consider the time. As mentioned earlier, the time you will spend training the new employees is enough risk to take.

You are not only taking a risk to hire and train alone, but you are also taking the risk of employing someone who may not stay with your company long enough to generate qualified leads. 

Outsourced sales development representatives hit the ground running from day one. They are cost-effective, and you don’t have to wait for a long time before you get results. 

3. Flexibility

An additional bonus of hiring outsourced SDRs is that you can scale up and down when needed. For instance, let’s say you want to push sales before the end of a particular holiday, like Christmas.

You can request additional outsourced SDRs from the B2B lead generation agency to increase capacity, and have them stand down after the rush is over. 

On other hand, if it were an in-housed SDR, you could have them overworked, which could lead to burnout. Besides, you won’t be able to stand them down when the rush is over, thereby incurring more costs. 

Another advantage to an outsourced SDR firm is that you can use them as your business grows. They can help you reach out to more customers, make more sales, and positively impact your ROI.

In short, outsourced SDRs allow your business to be more flexible as they can try out new processes and scale up and down when necessary. 

Top 10 outsourced SDR as a service companies 

1 – Nerdy Joe

As a lead generation service agency, Nerdy Joe also specializes in providing outsourced SDR services. Basically, we collaborate with you and your sales representatives to develop comprehensive sales strategies that incorporate effective lead generation tactics, to begin with.

Our approach involves identifying target customer segments, gaining insights into their preferences and needs, and devising strategies to attract and convert them into leads for your sales team to close easily. 

We believe lead generation is one of the sales activities you can outsource to free up time for your salespeople. So, technically, our team operates as an extension of your internal sales team, managing all aspects of lead generation on your behalf while your sales team focuses on having meetings and closing deals.

Also, our experts analyze your business or sales team’s existing sales processes to identify areas for improvement, particularly in the realm of lead generation. 

We assess the effectiveness of different lead generation techniques and optimize them to generate higher-quality leads with a higher likelihood of conversion.

What sets us apart from other outsourced SDR companies is our unwavering commitment to quality. We understand that generating leads is only half the battle; the true challenge lies in converting those leads into loyal customers. 

Therefore, we focus on generating leads that are not only interested in your product or service but are also more likely to convert into paying customers.

We recognize that every business is unique, and that’s why we offer customized lead generation solutions tailored to your specific needs. We will work closely with you to understand your distinct requirements and deliver the results you’re seeking.

Why you need to hire Nerdy Joe’s service as a sales consultant firm

As mentioned before, we understand that outsourcing lead generation can be a strategic move to optimize your sales team’s time and resources. Here are some compelling benefits that make us the ideal choice for your outsourced SDR service.

A steady stream of ready-to-buy leads per month

Many sales teams who work with lead generation companies often encounter issues with unfulfilled promises and unreliable services. These companies typically fall into various categories:

  1. Those who charge based on the number of emails or contacts they send, without guaranteeing any results.
  2. Those who charge a monthly fee, promising high-quality leads but failing to deliver on their promises.
  3. Those who classify every download of an ebook or PDF as a lead and charge for it.
  4. Those who bring in leads that never convert into actual customers.

However, we believe that the true value of an outsourced SDR team that does lead gen for you lies in the results it delivers to your sales team. Specifically the number of hot leads they generate and add to your sales pipeline. 

That’s why at Nerdy Joe, we only charge based on the number of qualified leads we generate for your sales team.

Our experts focus solely on metrics that align with your goal of increasing leads and driving more sales, eliminating vanity metrics such as the open rate or bounce rate — we don’t know if these are metrics you need to care about.

For example, if you choose to work with us to boost the customer base for your SaaS product, we will provide reports on the number of new sign-ups, positive replies, demo calls booked, and new clients acquired.

Right from the beginning, we work collaboratively with you on a sales development strategy that guarantees the results you desire. We set clear KPIs and OKRs, and devise strategies to ensure we meet them, providing you with a solid plan for success.

Excellent outreach strategy and campaign with strong personalization

If you’re familiar with how most lead generation companies operate, you know the typical modus operandi before the outreach is as follows:

  • Use a tool to build a list of thousands of prospects
  • Work internally to hand-curate those lists
  • Create an ideal customer persona and create an email or message template accordingly
  • Then start sending thousands of emails on your behalf. 

Another way to look at it is that they rely on data intelligence tools to hastily compile lists of prospects that are then bombarded with impersonal, one-size-fits-all cold emails or messages.

But here’s a thought-provoking question for you: how do you want your brand or company to be perceived? And which type of agency would you prefer to work with?

  • A: An agency that churns out generic emails to thousands of people, hoping for a reasonable conversion rate. 
  • B: An agency that meticulously researches and curates a smaller list of 30 prospects, crafting personalized, relevant, and compelling messages to engage with them and achieve a higher success rate.

B, right? That’s exactly what we thought.

Sure, the A agency may still achieve some results. It’s tempting to believe that the more cold emails you send, the more clients you’ll close. But in reality, this approach can harm your brand and relationships with potential clients in several ways.

  • Your emails and IP addresses may be flagged as spam by ESPs and ISPs. 
  • Your company’s reputation could suffer, with negative feedback on social media. 
  • The quality of leads generated may be low. 
  • Deliverability issues may plague your domain.

To avoid these pitfalls, we take a different approach. We carefully select our target audience and craft personalized messages for a small, highly-relevant prospect list. And guess what? It works.

The cornerstone of our strategy is to thoroughly understand your ideal customer profile (ICP) before writing any cold emails. We want each recipient to take you seriously, feel like you understand them, and wonder why you didn’t connect sooner.

We’re not interested in sending a thousand emails a day for a week just to secure a handful of sign-ups or meetings. Our goal is to send 20 carefully-crafted emails, receive 15 replies, generate 10 positive responses, and ultimately deliver 4 sales-qualified leads or sign-ups.

To give you some context, here’s an example of a reply we received from a VP of Marketing who has a history of blocking or reporting spam from cold email senders as we reached out to them.

Here’s another example where we pitched a Head of Marketing, and here’s the response. 

Wondering how we gather insights on your prospects or target audience for personalized communication? 

We delve into their digital footprint, from podcasts, they’ve appeared on, and blog posts they’ve penned, to their social media activity on platforms like LinkedIn, Twitter, and Mastodon. We even scour forums they actively participate in. 

Armed with this valuable data, we create tailored first lines and icebreakers that resonate with each individual. 

Curious to see it in action? We recently approached Ben Sailer, Head of Content at CoSchedule, with a pitch to write for them.”

Here’s what he replied 1 hour later.

As you can see, the cold emails were so compelling that they couldn’t help but acknowledge it before offering to hire us. 

Manual prospecting and list building to guarantee excellence 

We take immense pride in our diligent approach to building prospect lists and executing campaigns without cutting any corners. 

You already know how we don’t purchase lead lists or scrape data from sales intelligence tools like Apollo, Lusha, or ZoomInfo. 

We think they only provide generic technographic and demographic data, such as:

  • industry, 
  • employee count, 
  • funding status, 
  • location, 
  • tech stack,
  • etc 

These are very basic, and the real issue is that they tell us nothing about the actual pain points your customer is having or why they should be part of the people we target. 

So, we go above and beyond to achieve deeper personalization. 

We prioritize data accuracy and customization to make sure our unsolicited cold emails stand out and grab the attention of potential prospects.

We seek out psychographic data and other relevant insights to truly understand prospects and their unique challenges in their day-to-day operations. Here is how we do it:

When we bring on a new client, our first step is to delve into their Ideal Customer Profile (ICP). We ask in-depth questions to uncover crucial information. Here are the question we ask:

  • which clients have the highest lifetime value, 
  • which ones are easiest to close, 
  • which ones churn the fastest, 
  • common objections heard during sales calls, 
  • the motivation behind starting their company, 
  • the pain points they were trying to address, 
  • and more.

From there, we can precisely pinpoint the most relevant prospects and manually curate our prospect lists accordingly. 

Understand that our approach goes beyond generic targeting like “series A tech companies” and instead focuses on a level of specificity that resonates with prospects on a personal level.

For instance, we can get as specific as targeting “CTOs at software companies selling to DevOps, with identified pain points of lack of organization, time management, and team collaboration, and a preference for XYZ podcasts for team management insights”.

With this data, we meticulously handpick prospects for your lead generation campaigns, ensuring the highest quality data for personalized outreach that captures attention and drives meaningful results. 

We believe that putting in the effort to truly understand and connect with prospects is the key to outreach campaigns that deliver outstanding outcomes.

No binding contracts needed

Outsourced lead generation services often require clients to commit to a 3 to 6-month contract before commencing work, citing the need for testing and acknowledging the potentially lengthy purchase journey. 

However, this approach may leave you, as the client, feeling disheartened, as you’re obligated to pay every month regardless of the outcomes you see.

That’s why we offer a subscription-based model for our services. With us, you can expect tangible results right from the first month, and you have the freedom to decide whether to continue or discontinue based on your satisfaction and budget.

This puts you in control and ensures transparency, so you know exactly what you’re paying for upfront without the stress of long-term and binding contracts.


Our marketing service’s pricing is crystal clear. We have three plans:

  • Silver: It costs $499/month and only gives you two warm LEADS.
  • Gold: This is the plan we recommend, as it gives you the biggest bang for your buck. It costs $999/month and gives you 6 hot and sales-qualified appointments or LEADS.
  • Platinum: This plan is for mid-level to enterprise companies willing to fuel their sales team with up to 15 sales-ready leads on a monthly basis.

Our email marketing pricing includes the following:

  • The tech stack we use to build your prospect list and send and monitor your campaign.
  • A complete list of prospects that fit your buyer persona and ICP.
  • The campaign setup fees.
