Nerdy Joe

Nerdy Joe is a B2B digital marketing agency that only offers email marketing and outbound lead generation services. We keep our service offerings narrow because it helps us do our job in the best way possible.

Working with us is pretty straightforward as we don’t require you to commit to a certain number of months, and you know exactly what you get when you choose to work with us.

Why’s Nerdy Joe the Best Outbound Lead Generation Service for B2B SaaS

Here are some reasons why Nerdy Joe is one of the best lead generation companies in the US.

You pay for results — not the jobs to be done

Working with most outbound lead generation services really comes down to these 4 scenarios:

  • They charge you for the jobs to be done, meaning you pay them to send X amount of emails per month. 

e.g., You pay $500, and we’ll build a list of 250 prospects per month.

  • They charge a flat fee per month to do lead generation for you, and they’re vague as to what the results will be. 

e.g., You pay $3,000, so the outbound lead generation service provider can run campaigns for you, and the results are just a matter of “it depends.”

  • They charge you a flat fee on a monthly basis and send you leads that aren’t close to being warm, let alone qualified.

e.g., You pay $1,700 per month, and they send a list full of people who have downloaded an ebook and call them leads.

  • They charge you for each qualified lead they bring, or you pay a flat fee, and they get a certain number of sales-qualified leads every month.

e.g., You pay $1,000 per month, and they generate leads (5 or 7) for you every month, and it’s up to you to close these leads based on your sales cycle and sales funnel. 

Without a doubt, the best outbound lead generation service for B2B SaaS is the agency that charges your SaaS company per qualified lead. 

At Nerdy Joe, we know that there are jobs to be done to get your software company leads. To be fair, that’s part of every agency’s lead generation process. We don’t just charge you for the job to be done.

 Instead, you pay for the ROI (return on investment) you get.

That means instead of charging you for the number of prospects we put in your campaign list or for the number of emails we send on your behalf, we charge you for the number of meetings we book for you or for the number of high-quality leads we send your way.

We do this because we know for a fact that every SaaS business struggling to increase its sales cares more about filling its pipeline with quality leads than the number of emails its sales teams send on a monthly basis. 

As simple as that.

When you start working with us, our outbound lead generation experts only lead with metrics that matter:

  • The number of meetings booked.
  • The number of “YES” and positive replies.
  • Lead to close rate.

Not the usual open rate, clickthrough rate, bounce rate, etc.

For instance, we have a client that’s a service-based business. They wanted to increase the number of quote requests they get on a month-to-month basis. 

Here are the metrics we report to them:

  • The number of clicks we get on each CTR. 
  • The number of positive conversations we have with prospects. 
  • The number of quote requests.
  • And the lead to close requests.

If you’re an e-commerce brand selling to individuals, we’ll only charge you for the number of orders we get for the company. 

The bottom line, the results we get for our clients depend on their company goals and context. We simply don’t have a one-size-fits-all lead generation. 

We don’t play the volume game — we personalize every single email

Cold email is not dead.

It’s just the playbook of nowadays self-proclaimed cold email gurus that’s outdated and shabby.
You’re probably familiar with some of these.

  • “Send 1000 cold emails a day.”
  • “Use Copy AI to flip some personalized first lines.”
  • “Buy 10,000 contact data from UpLead and send 300 emails a day.”

While this tactic seems to bring some leads for the people who run such campaigns, there’s a big difference between the quality of leads they get and that of someone who sends a cold email that reads personal, relatable, and timely.

Personalization and relatability make people reply to you even when your timing is not great.

Here’s an example of where I reached out to a Global VP of Marketing, but the timing wasn’t great.

Still, she took the time to reply and communicate an appropriate time when it makes sense to touch base.

Personalization is what makes people who are averse to cold outreach reply to your cold email.

Here’s an example where we reached out to a VP of Marketing who has historically blocked or reported SPAM to anyone who’s sent him a cold email.

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

Contrary to what these gurus suggest, most of our outbound lead gen campaigns are run towards 10 or 15 people, not 1000.

That’s because we simply believe that the best sales strategy is to build trust and relationships. That’s why most of the responses we get are:

  • “Wow, such a nice email, Ernest.”
  • “Thank you for the nice words and compliment, Ernest.”
  • “Let’s catch up next Thursday.”
  • “Ernest, love your email. Can you follow up on the 25th?” 

Now, you’re probably wondering what our process is for nailing the personalization part of our campaigns. Where do we get information about each prospect?

Well, glad you asked.

  • We watch interviews and podcasts your target audience has participated in.
  • We read blog posts and thought leadership articles they wrote or contributed to.
  • We read their comments and posts on LinkedIn, Twitter, and Mastodon.
  • We read their company’s new mentions.

We then combine all of the information we collected to find unique angles and craft personalized first lines or icebreakers.

We don’t use purchased data or scrapped information — we build our data manually 

First things first, we don’t build our campaign data manually because we’re old school or like working hard.

We simply don’t use client data or purchase data when running outbound lead generation campaigns because this data is rarely accurate. 

The reason for this is very simple:

  • Most of this data is not updated. For example, with the great resignation, a lot of companies lost their talent. Some laid off thousands of employees, some of the people found new jobs, and some stayed jobless. So in most cases, you’ll likely end up with non-actualized data.
  • Most of these tools come at a hefty cost and aren’t worth the investment due to the number of email addresses that bounce back.
  • These tools are just good at finding prospects based on demographic and technographic data. And what really matters for our campaigns is the prospects’ psychographics. (i.e., what they really like, what podcasts they listen to, what publications they read, etc.?)

For example, using ZoomInfo or Lusha, it’s easy to find prospect data using filters like the following: 

  • The company is in the crypto trading industry, 
  • 50 to 500 employees,
  • Raised capital,
  • Based out of Austin, Texas,
  • Uses AWS for hosting and Magento.

Now, as much as you want to personalize your cold emails, what can you do with this data?

So, instead of relying upon this type of data, we go one step further and ask questions like the following:

  • What does your ideal customer look like?
  • Which category of clients has the highest lifetime value?
  • Tell me about one client you closed in an easy way.
  • Tell me about the category of clients that churns the fastest.
  • Tell me about the top 3 objections that constantly pop up during sales calls.
  • Etc.

We use the answers to these questions to identify your ICP and buyer persona

And you can tell this type of information makes the difference between: 

“Our target is series A crypto trading companies,” 


“Our ICP is a VP of Partnership at a crypto trading company, and his main pain points are that he struggles to close partnership deals with influencers, he does not know how to reach out to influencers. He often refers to TikTok and Gumroad’s blog to get insights as to how to influencers think.” 

Once we have a clear understanding of who the ICP is, we proceed to manually build our list, and that’s what we use to run our lead generation campaigns.

We don’t require you to commit to a 3-month contract

Nerdy Joe is a subscription business, and you only renew your subscription if you’re satisfied with the service. 

Unlike most outbound lead generation services that require you to commit to a 3 to 6-month retainer, working with us means you get results starting from Month 1. And if you’re happy, you can renew your subscription.

Also, because you know exactly what you are paying for, we don’t send you proposals based on surface-level information we have about your company. We also don’t waste your time with useless meetings. 

You get what you pay for — depending on the plan you choose; you know exactly what you get 

Nerdy Joe’s offerings and pricing are clear — and this is probably why we’re one of the best lead generation agencies. You choose a plan based on your budget and needs, and you know exactly what you get at the end of the month.

  • No “it depends on a lot of factors.”
  • No “Your account manager swallowed the key to his office and couldn’t work.”

If you have product-market fit and are solving a problem that most people have, it is almost everything we need to get you results.

But if you’re still figuring out who your solution is best for, then we’re probably not going to be of help.


Our lead generation service’s pricing is crystal clear. We’re three plans:

  • Starter: It costs $499/month and only gives you a warm LEAD.
  • Boss Mode: This is the plan we recommend, as it gives you the biggest bang for your buck. It costs $799/month and gives you 5 hot and sales-qualified appointments or LEADS.

5 Outbound Lead Generation Strategies to Boost Sales for Your B2B SaaS

Let’s discuss some outbound lead generation strategies you can use to  boost sales for your B2B SaaS 

1 – Cold email

Cold email is an effective strategy for marketers dealing with outbound marketing. Although many think it is obsolete, it has numerous advantages as long as you use it correctly. 

After all, the cold email conversion rate as of 2021 stood at 15.11%. Interestingly, the average ROI for cold emails is 3,800%. In other words, you receive a $38 return for every $1 you invest.

Besides, a study by Hubspot revealed that 80% of prospects prefer to be contacted by email than any other marketing channel. This implies that cold email remains one of the most effective strategies you can use to reach out to your audience.

But, how do you craft a cold email copy that captures your prospects’ attention and gets you replies?

  • Research your ICPs
  • Personalize your messages
  • Craft a catchy subject line
  • Include a clear and compelling CTA
  • Send some follow-up messages
  • Know when to stop to avoid spamming your subscribers

2 – Cold calling

Just like cold emails, cold calls are also effective for outbound lead generation. The result you obtain often depends on how you use it.

The best way to do cold calling is after sending a few cold emails. This happens when your prospects have gone silent on your messages or after they know you.

When you intend to make cold calls, here are a few tips you can consider.

  • Know your prospects
  • Craft a personalized calling script
  • Provide value by holding conversations that build relationships
  • End the call by confirming what the next step is.

3 – LinkedIn cold messages

LinkedIn is another great means of connecting with your prospects and knowing their interests. Not only can you check their background on this platform, but you can also curate your profile to increase brand awareness. 

At least 4 out of 5 LinkedIn members drive business decisions, and 50% of B2B buyers go to LinkedIn when making a purchasing decision. Hence, it is a critical part of your outbound lead generation. Before you send a LinkedIn cold message, here are some tips you can consider.

  • Find common ground between you and your prospects
  • See if a mutual connection can introduce you
  • Craft a short and catchy message
  • Build a relationship before you sell
  • Give them a good reason to reply to your message
  • Follow up on your prospects

4 – Social selling

Social selling isn’t obsolete. It happens when a sales rep connects with leads to grow their brand. It is identical to a cold call, as the connection is made in person. Social selling occurs on platforms such as Facebook, Instagram, and Twitter

Companies that want to try this should research their ICPs and have a sales strategy before contacting them. 

Cold outreach on social media is a great way to engage your prospects without disturbing them. Here is an example of a cold outreach on Instagram.

5 – Referrals

Referrals occur when your existing customers become brand advocates and share information about your company.

Inbound referrals occur when someone comes to you after hearing about your company from someone else. 

Meanwhile, outbound referrals require you to make contact with someone whose name you were given. It also occurs when you contact a prospect, and they tell you they aren’t the right person but refer you to someone else. 

Although they aren’t as qualified as inbound referrals, they remain relevant as a part of outbound lead generation. Here are some tips when contacting an outbound referral.

  • Start by requesting an introduction to your prospect. This should come from a referee.
  • Make a positive interaction by wording your request as if you are seeking assistance. For instance, you can say something like, “I was hoping you could help me with something: we are currently expanding our business.”
  • Treat your recommendations like VIPs by offering them exceptional services. This could prompt them to send you to another referral.

Which Lead Generation Agency Is Best For Your Company? 

If you’re just looking for an agency that’ll use paid ads to boost your sales, Single Grain and WebFX are the lead generation agencies for you.
