The Cold Email Comeback: Smarter Lead Gen Tactics for Today’s Sales Teams – with LevelUp Leads

The cold email has been around since the early days of free email, circa 1996. And despite newer, flashier channels like social media and influencer marketing stealing the spotlight, it never really left the room and remains a preferred form of lead generation. In fact, it’s making a quiet but strong comeback. 

Why? Because when executed well, cold emailing is one of the most effective ways to reach potential customers. It’s simple and scalable, and when paired with personalization and lead generation tactics, it works. 

The catch is knowing the difference between an email that gets flagged as spam and one that makes someone think, “Maybe I should check this out.” It comes down to strategy, content, and sales teams that understand this achieve consistent results — emails have one of the highest returns on investment (ROIs) in the outreach playbook. 

Let’s take a look at some lead generation tactics and tools you can employ to make the most of it. 

What’s the Ideal Email Open Rate? 

Before diving into tactics, it’s helpful to know the results you should be aiming for. According to lead generation agency LevelUp Leads, a solid benchmark for cold email open rates falls between 15 and 25%. Hitting that range means your subject lines, send times, and deliverability are all working in your favor. 

Keep in mind that open rates aren’t the same as response rates. Your open rate tells you how many people looked at your email, while the response rate reflects how many replied. 

Note: In 2025, open rates are becoming obsolete, and most cold email users have switched to tracking reply rates and positive reply rates. Positive reply rates give you the best idea of how well your campaigns are performing.

That said, these numbers will vary depending on your industry and audience. For example, a campaign targeting enterprise healthcare buyers will behave differently from one for SaaS managers. 

But whatever your niche, if you’re consistently landing below that 15% mark, it’s time to take a closer look at your sender reputation, email list quality, subject lines, and more. 

Success Factors

The email you send is only a part of your success rate. Many other factors influence the success of a cold email campaign.

1. The Right Person, Right Time Factor 

Even the best subject line is useless if it lands in the wrong inbox. That’s why effective cold email outreach starts with a high-quality, intentionally built list of addresses. 

This means doing your homework. Building a smart list involves more than just scraping names from LinkedIn. Instead, take the time to identify people who are more likely to need — or at least be curious about — what you’re offering. This process is known as intent-based targeting and intelligent segmentation. 

Alongside this in-depth research, prioritize good data hygiene. Data hygiene is keeping your email list accurate, current, and free of bad or irrelevant contacts. 

Sending emails to outdated or unverified addresses will negatively impact your open and reply rates and potentially damage your sender reputation. Email sender reputation is a score assigned by Internet Service Providers (ISPs) to gauge the trustworthiness of an email sender. 

To avoid this, it's essential to regularly clean and validate your email list to ensure you're reaching the right audience. Marketo email marketing services can help you manage and optimize your email campaigns, offering tools to maintain a healthy email list, improve deliverability, and boost your overall email performance, all while safeguarding your sender reputation.

Ultimately, a clean, validated email list gives your emails the best chance to perform. 

 2. Content Relevancy 

Getting in front of the right person is step one. Saying something that matters to them is the second.  

Content relevance comes down to knowing your audience and tailoring your message to match. For example, a CEO and a department manager might both be part of your target account, but they care about different things. A decision-maker wants to hear about ROI and strategy. A manager might be more interested in the ease of implementation or how your product can take some work off their hands. You’ll miss the mark with at least one of them if you send the same message to both. 

That’s why email list segmentation and content alignment go hand in hand. The right message, framed for the right role, makes your cold email feel more like a timely conversation and less like a generic sales pitch. 

3. Email Frequency 

More emails don’t mean more results. In fact, sending too many too quickly can hurt your campaign and your brand. 

As you can probably tell by now, cold outreach works best when it’s intentional. A few well-timed, well-written emails will always outperform a flood of generic follow-ups. You’re more likely to annoy a person than convert them if you’re reaching out every other day. 

Plan a smart cadence that gives the recipient time to read, consider, and respond before you follow up. 

Three to five emails over two to three weeks is a solid benchmark. This keeps you top of mind without overwhelming the prospect. 

A sample email cadence can look like: 

• Day One — initial cold email 
• Day three or four — first follow-up email 
• Day seven or eight — second follow-up (maybe with a new angle or value-add) 
• Days 12 to 14 — final follow-up 

Adjust frequency according to industry, role, and the person’s prior engagement with your brand. For example, C-suite targets may require a slower, more respectful pace. 

4. Deliverability 

Finally, all the above factors are moot if your emails aren’t landing in the inbox. 

Deliverability refers to whether your emails arrive in the recipient’s inbox instead of being filtered as spam. Even the best-crafted message is ineffective if it never gets seen. 

To improve deliverability, use a verified domain, warm up your email account before starting campaigns, and avoid spam-trigger words in your subject lines and email body. Terms like "free," "special offer," and "money-back guarantee" are common red flags. 

A few other things to remember that help with email deliverability are having a clean email list, warming up your emails for sender reputation, proper segmentation, and having the right infrastructure and email marketing tool that works for your email campaigns.

Additionally, avoid sending large-scale email blasts and keep your text formatting simple. 

Smarter Emails for Smarter Results  

Let’s say you’ve nailed your targeting and landed in the inbox. Congrats, you’ve earned a reader. 

Now comes the real test: holding their attention long enough to spark action. 

Today’s audience is busier, pickier, and bombarded with emails daily. Not to mention, our attention spans are shrinking and tolerance for fluff is low. Your cold email will be ignored or deleted if it doesn’t immediately show value — no second chances. 

Here are some email writing tips to keep in mind: 

• Write a Subject Line Worth Clicking 

Your subject line should grab attention without sounding like clickbait. Spark curiosity or highlight value with short, punchy, and outrightly relevant information. 

Do not use all-caps or exclamation marks. This is a professional email, not a sales promotion. 

• Personalize (But Make It Count) 

Email personalization only works when it’s real. Readers immediately recognize a generic “Hi [First Name]” template. 

Instead, focus on relevance. Reference something that shows you’ve done your research on the customer or their company, then lead with content that is useful to them. Show that you understand their role, their challenges, and how you can offer solutions. 

Avoid being excessive, however. People generally react negatively to insincere or obvious appeals to their emotions. 

• Offer Upfront Value 

Do not make the reader dig for the point. Your email should answer the question, “Why should I care?” within the first few seconds. 

A statistic, a free resource, or a sharp insight are useful things you can mention right away, just make sure it ties back to the problem you can solve. 

• Keep It Short 

Remember, this isn’t a pitch deck. As a general guideline, aim for three to five concise sentences. Your reader is probably checking their phone between meetings, so respect their time by keeping your message focused on the key points.

• Use a CTA That Does the Work for Them 

Finally, make the next step easy and frictionless. Instead of vague asks like “Let me know what you think,” try “Do you have 15 minutes on Tuesday or Thursday to talk through it?” A clear, low-effort call to action makes it easier for them to say yes, or at least respond. 

Smart writing supports a smart cold email outreach campaign. 

Practice Makes Conversions 

It’s perfectly fine if you don’t achieve the perfect cold email strategy at the start. Real progress comes from testing and making iterative improvements. Even small adjustments like tweaking a subject line, refining a CTA, or changing send times can significantly improve your results. 

View your cold email outreach as an ongoing process, not a one-and-done event. Regularly monitor your metrics, testing one variable at a time, and adjust based on what the data tells you. 

Tools like Smartlead, Mailshake, Lemlist, and Woodpecker make data-driven optimization much more streamlined and accurate. 

Keep testing and let the data guide your next move. These incremental improvements accumulate over time, turning average campaigns into highly effective lead generators. 

Takeaway: Refine and Conquer 

Cold emailing is far from obsolete. All it takes is smarter strategies, sharper targeting, and a dedication to refinement. Those who look at it as a skill they can improve will ultimately see results.
