Sales development representatives (SDRs) are the engine room of any lead generation agency.

They’re the folks who track down high-value prospects, engage them through cold outreach, and book sales meetings.

But what are their specific responsibilities? What skills do they need to thrive in the role? And what tools can they use to smash their targets?

Read on to find out…

What Is a Sales Development Representative?

A sales development representative is a front-line sales rep tasked with identifying and connecting with potential customers — typically at the start of their buying journey.

In the context of a lead gen agency, they find and engage prospects who are likely to be interested in their clients’ products or services, with the goal of building the client’s sales pipeline. To do this, they use a range of cold outreach tactics, including:

  • Cold email

  • Cold calling

  • LinkedIn messaging

  • SMS

SDRs don’t actually close the deal themselves. Instead, when they’ve struck up a rapport with a prospect, qualified them as a lead, and booked a sales meeting, they pass the details onto their client.

What Does an SDR Do? 5 Responsibilities

Now that we understand the purpose of SDRs, let’s drill down into their core responsibilities:

1. Generate Prospect Lists

Prospecting is at the heart of the SDR role.

Specifically, they have to generate lists of prospects that align with their client’s ideal customer profile (ICP) and buyer personas.

Given that sales development reps at lead gen agencies handle multiple clients simultaneously, they must be highly adaptable — capable of constantly switching from one ICP to the next at short notice. 

We’ll talk more about the key skills and traits of successful SDRs in the next section.

2. Book Sales Meetings

Once they’ve identified the perfect prospect, the SDR’s next task is to reach out to them via one or more cold outreach channels. They might pick up the phone, send them an email, and connect with them on LinkedIn — all with the ultimate goal of securing a sales meeting for their client.

3. Follow Up With Prospects

Of course, not all prospects will respond to that initial email or cold call.

In fact, QuickMail’s own cold email statistics — collected by analyzing 1.7 million emails sent through our platform — discovered that 55% of cold email campaign replies come from a follow-up email.

And with the optimal campaign comprising three follow-up emails, SDRs must be persistent to achieve the desired results.

4. Share Relevant Sales Collateral

Okay, so we know that sales development representatives spend a bunch of time speaking to prospects.

But what, exactly, do they say?

Even the best SDR can’t do all the selling themselves. Instead, they rely on sharing persuasive, targeted sales collateral like:

  • Case studies

  • Client testimonials

  • Industry news and reports

  • Unique research

  • Blog posts

This content is designed to educate their prospects and/or demonstrate the value of their clients’ products or services.

5. Share Results

Even when a company outsources lead generation to an external agency, they still need a clear picture of their sales pipeline.

That’s why reporting is another key SDR task. Typically, this involves sharing the results of their prospecting and outreach efforts — either with an agency-side account manager or directly with the client.

Pro tip: With QuickMail, agencies can invite clients as guests (at no extra cost) and build analytics dashboards providing a real-time view of activity and performance.

So SDRs don’t need to worry about generating manual reports — freeing them up to spend more time on revenue-generating tasks.

5 Key SDR Skills

A survey of hundreds of B2B SDRs identified the top five skills and traits that sales development representatives need for success. Let’s take a look at the results:

  1. Adaptability: Not only do SDRs at lead gen agencies need to juggle multiple clients, but they also have to be comfortable reaching prospects via a range of channels. 

  2. Positive attitude: SDRs have to believe that their next meeting booking is just around the corner, even if they’ve faced a string of rejections.

  3. Resilience: Realistically, every sales development representative will hear “no” far more often than “yes”. Top-performing reps don’t let these setbacks derail them.

  4. Curiosity: If you’re going to be prospecting for hours a day, it helps to have a natural desire to learn more about industries, companies, and people.

  5. Sociability: Let’s be honest — if you’re no good at speaking to people and making them feel at ease, you’re unlikely to make it as an SDR.

That’s not to say every sales development representative has each of those skills. But they’re a good indicator of likely success.

12 Essential Tools for SDRs

Once upon a time, sales was all about cold calling and door knocking. The only technical skills they needed were the ability to dial a phone number and read a map.

  • Sales prospecting
