Tracking email open rates used to be the go-to way to measure your email’s success.

But today? Open rates have become pretty much obsolete.

Why? Because with so many inboxes blocking images, auto-previewing emails, and the rise of privacy features, that “open” number just doesn’t tell you what you really want to know:

‍Did your email get a response?

I’ve been there, watching those open rates climb but never seeing replies. It’s frustrating! That’s why it’s time to focus on what truly matters: response rates.

After all, a real conversation, a reply, or a click is what moves the needle in sales, networking, and relationship building.

So in this article, we’re diving into six proven techniques to track email response rates effectively, helping you better understand your outreach impact and improve your follow-ups.

Why Focus on Response Rate Instead of Open Rate?

Open rates have long been the standard metric to judge email success, but here’s why they’re losing relevance:

• Image Blocking and Privacy Changes: Many email clients block tracking pixels by default, skewing open data.
• Auto-Previews and Notifications: Some emails show as “opened” even if the recipient didn’t read them.
• No Action Taken: An open doesn’t mean interest—response or click behavior tells you more.

Response rate measures actual engagement and tells you who’s truly interested and likely to move forward. Tracking this metric helps prioritize leads, tailor your messaging, and optimize your outreach strategy.

B2B Cold Email Response Rate Benchmarks: Cold email response rates vary across industries, job roles, and campaign quality. But here’s what the data says:

Average response rate: 1%–5%

Good campaign: 5%–10%

Top-performing campaigns: 10%–25%+

Smartlead users: Some campaigns reach 40%+ response rates

Pro Tip: If you're consistently getting <2% response rates, it's time to rethink your targeting, messaging, or deliverability setup.

6 Ways to Know if Someone Responded to Your Email

In today's digital age, email communication is essential, both personally and professionally. Whether it's for business proposals, job applications, or staying connected with friends and family, knowing if your email has been opened can be crucial. Here are six techniques to help you track the fate of your emails:

1. Use Email Tracking Tools with Response Notifications

Modern email tracking tools like Smartlead.ai, don’t just track opens, itn notify you when someone replies. These tools can alert you instantly to incoming responses, helping you act quickly and keep conversations moving.

They also provide detailed analytics on your emails, including reply rates, so you can see which messages are sparking conversations and which ones need tweaking.

Best Time to Send B2B Cold Emails

Based on industry-wide studies and Smartlead performance analytics:

• Best Days: Tuesday & Thursday
• Best Times: 8:00 AM to 10:00 AM (recipient's local time)
• Avoid: Weekends, Fridays after 2 PM, or late evenings

Timing your outreach right can give you an immediate lift in replies.

2. Set Up Automated Follow-Ups Based on No Response

One smart way to track responses is to automate follow-ups. If your email tracking tool or CRM detects no reply within a set timeframe, it can trigger a follow-up email.

This method not only helps you stay persistent but also indirectly tracks response behavior—if someone replies, the automation stops; if not, you get a timely nudge to reconnect.

3. Monitor Link Clicks as Proxy for Engagement

While open rates are unreliable, tracking link clicks in your emails is a much better indicator of interest. If a recipient clicks a link, it means they engaged with your content and are more likely to respond.

Use unique, trackable URLs in your emails so you can see exactly who clicked and when. This insight lets you prioritize follow-ups for the most engaged recipients.

‍

4. Request a Clear Call-to-Action (CTA) That Invites Replies

Make it easy for recipients to respond by including a clear, direct CTA in your email—like asking a question or requesting feedback.

If your email management tool supports it, track replies to that CTA specifically. For example, if you ask “Are you interested in learning more? Reply YES or NO,” you can track those simple replies as clear indicators of engagement.

5. Use CRM Integration to Track Conversation Progress

If you use a Customer Relationship Management (CRM) system, integrate your email platform to log every reply automatically. This helps you track the status of your outreach and response rates without manual effort.

CRMs can also alert you when replies come in, and track longer-term engagement metrics, turning your email outreach into a seamless part of your sales or networking pipeline.

6. Leverage Third-Party Email Plugins for Real-Time Response Alerts

There are many browser plugins and extensions like Mailtrack, Mixmax, or Boomerang that provide real-time notifications when someone replies to your email.

These tools are great for staying on top of your inbox and responding promptly, which can boost your chances of converting conversations into opportunities.

Smartlead in Action: How Before Hello Achieved 20%+ Reply Rates Using Smartlead

Let’s talk about what happens when everything clicks, our targeting is dialed in, your value proposition resonates, and your tech stack is optimized for deliverability.

That’s exactly the story of Before Hello, a B2B email agency led by Oleksandr Ivanets, who turned cold emails into consistent revenue generators by doing one thing exceptionally well: focusing on conversation-first campaigns backed by Smartlead’s infrastructure.

Before Hello had already mastered the art of cold outreach—but as email providers like Gmail and Outlook tightened spam filters, even great messages were getting lost.

They ran into four big problems:

• Inbox deliverability was slipping due to outdated tools.
• Prospects were tuning out generic sales copy.
• White-label dashboards for clients were becoming too expensive to maintain.
• Tech stacks were fragmented, slowing their workflow.

As Oleksandr puts it:

“Most cold emails fail because they’re transactional, not conversational. We knew that scaling our campaigns meant we needed tech that could support personalization and deliverability at scale.”

The Smartlead Solution

Here’s how Smartlead helped Before Hello scale reply rates across industries like SaaS, fintech, and healthcare:

Smart Delivery & Inbox Rotation

• AI-powered IP/domain rotation to mimic natural sending behavior
• Smart warmups and spam phrase detection ensured 95%+ inbox placement

White-Label Client Dashboards

• Real-time reporting on opens, replies, spam rates
• Saved $1,000s in custom dashboard development

Behavior-Based Sequences

• Follow-ups paused automatically after a reply
• Conversational CTAs like: “We helped [competitor] reduce churn by 30%—want to see how?”

Community-Led Growth

• Access to 5K+ outbound experts in Smartlead’s Slack
• Weekly live webinars on deliverability, reply strategy, and more

From February to April 2025, Before Hello tracked:

• 20%+ average reply rate across campaigns
• 68.53% positive reply rate from over 5,000 cold emails
• 50% conversion rate from replies to booked meetings
• $10M+ revenue generated through cold outreach for 150+ clients

“With Smartlead, our emails land where they need to—and our messaging does the rest. That’s how we turn cold emails into closed deals.”

Before Hello’s story proves what’s possible when high-quality messaging meets high-quality infrastructure. If you're aiming to break through the 5% response rate ceiling, their approach offers a blueprint:

• Personalization > templates
• Deliverability > quantity
• Conversations > clicks

And most importantly, track and optimize for replies, not opens.

The Future of Email Tracking

The email marketing landscape is continuously evolving, and with it, so is email tracking. Here's a sneak peek at what the future might hold:

1. AI-Driven Insights: Artificial Intelligence (AI) is set to play a more prominent role in email tracking. It can help you analyze data more comprehensively, providing insights on the best times to send emails, subject line optimization, and even predicting which leads are more likely to convert.

2. Enhanced Privacy and Compliance: With increased scrutiny on data privacy, email tracking tools will evolve to ensure compliance with international data protection regulations like GDPR and CCPA. This will likely include more robust opt-in and opt-out features for subscribers.

3. Interactive Emails: The future might bring us emails that are more interactive. Imagine an email that allows the recipient to purchase a product or schedule an appointment directly within the email, all tracked and analyzed seamlessly.

FAQs

Can I track email replies without invading privacy?‍

Yes, focusing on replies and link clicks respects privacy more than invisible tracking pixels. Always be transparent about tracking.

What if recipients don’t reply but click links?‍

Link clicks are a strong engagement signal, even if no reply comes. Use this data to prioritize your follow-ups.

Are response rates better than open rates for all email types?‍

For outreach, sales, and networking emails, yes. For newsletters, open rates still have some value but shouldn’t be the only metric.

How Do Email Tracking Pixels Work?

Email tracking pixels are small, invisible image files or snippets of code inserted into the email body. These pixels are typically just 1x1 pixel in size and are hosted on a server. When the recipient opens the email, the email client loads the image from the server, and this "hit" triggers a notification to the sender or updates a tracking dashboard. This is how the sender knows that the email was opened, but it relies on the recipient's email client allowing images to load.

Can You Track Email Opens Without Recipient Knowing?

Email opens can usually be tracked without the recipient's knowledge, as tracking is generally invisible and passive.

What to Do if Your Email Isn't Being Opened?

If your email isn't being opened, consider improving subject lines, sender name, and email content. Experiment with different approaches and segment your audience.

Is It Possible to Know the Exact Time Someone Opened Your Email?

Most email tracking tools provide open time estimates, but exact times are often unavailable due to technical limitations.

How Accurate Are Email Tracking Tools?

Email tracking tools are generally accurate but may have slight discrepancies. They rely on recipient actions and email client support.

Do All Email Clients Support Open Tracking?

Not all email clients support open tracking, and some may require users to enable it manually.

Privacy concerns arise with email tracking, as it can infringe on recipients' privacy. Always respect email tracking regulations and user preferences, providing opt-out options.
