Independent Study Reveals High-Performance Email Outreach Metrics on Apollo.io in 2024
An independent 2024 study by the Tolly Group confirms Apollo.io's platform can produce email outreach results that significantly outperform typical B2B benchmarks. The evaluation centered on a live, from-scratch go-to-market campaign which achieved a 2.37% email-to-meeting conversion rate, a figure substantially higher than the widely cited industry average of 0.5% to 1.5% for cold outreach. [11, 13] This performance is particularly noteworthy given the campaign's context and the broader state of B2B email marketing. According to a 2024 analysis from Martal Group, average cold email reply rates have fallen to 5.1%, making the high conversion to meetings in the Tolly test a strong indicator of effective targeting and messaging capabilities. [5] The study's core objective was to provide a transparent assessment of the platform's outbound performance, the accuracy of its contact data, and its ability to drive conversions in a real-world scenario, lending substantial credibility to the outcomes. [11] The campaign also registered a 45% open rate, which surpasses the general B2B industry standard that various 2024 reports place between 21.2% and 37.7%. [3, 4]
The Tolly Group's methodology was designed to simulate a realistic and challenging sales scenario, strengthening the validity of its findings. Over a one-month period, the test involved contacting 384 target users across 205 different companies using the Apollo.io platform. [11, 13] This scale is representative of a typical, focused B2B prospecting effort. The campaign's primary goal, as detailed in the 2026 Go-To-Market Effectiveness and Data Quality Report, was to rigorously assess outbound performance metrics in a live environment rather than a controlled simulation. [11] The test specifically measured the entire funnel, from initial outreach to booked meetings, tracking 169 contacts who completed a full three-email sequence. Out of this group, 76 opened an email, 14 replied, and four scheduled a meeting, providing a clear and traceable path to the final 2.37% conversion rate. [13] This methodical approach provides a granular view of platform performance at each stage of the outreach process, from deliverability to genuine prospect engagement.
The campaign's success is further amplified by the fact that it promoted a completely new product from a vendor with whom recipients had no prior familiarity. [11] New product introductions inherently face an uphill battle for attention and typically record lower response rates due to a lack of brand recognition and established trust. Despite this significant handicap, the campaign's 45% open rate and 2.37% meeting conversion rate demonstrate the platform's capacity to overcome common market-entry barriers. For context, 2024 benchmarks show that even general B2B email campaigns struggle to maintain engagement, with click-to-open rates falling to 6.4% as users increasingly scan emails passively. [7] The Tolly evaluation also highlighted the efficiency of using a unified platform like the one offered by Apollo.io, which eliminates the need to toggle between disparate sales tools for list building, sequencing, and analytics. [11] This streamlined workflow, combined with high-quality data and effective targeting, proved capable of generating top-tier results even under challenging conditions, setting a new performance benchmark for go-to-market teams.
Email Prospecting Exceeds Benchmarks with 2.37% Meeting Conversion Rate
A 2024 independent evaluation by the Tolly Group documented a cold email campaign on the Apollo.io platform that achieved a 2.37% email-to-meeting conversion rate. [23] This performance significantly outpaces typical cold outreach results, where industry benchmarks for email-to-meeting conversions average just 0.1% to 0.4% in 2025 and 2026. [21] The Tolly study, which was a live test for a new service and not a simulation, sent a three-email sequence to 169 prospects, resulting in four booked meetings. [23] This conversion level is notable in a difficult market where the average deal-close rate from cold email was just 0.2% in 2025, or one deal per 500 emails sent. [1] The campaign's success, measured by converting unfamiliar prospects into scheduled appointments, places its performance well above the standard expectation for B2B prospecting, where reply rates alone have fallen from 5.1% in 2024 to 3.43% in 2026. [20] The result highlights the effectiveness of the platform's AI-assisted targeting and data quality in a real-world scenario.
The same Tolly Group campaign also recorded a 45% open rate, a figure that surpasses generally accepted B2B standards. [23] For context, broader 2024 email marketing data from GetResponse, based on an analysis of over 4.4 billion messages, shows an average open rate of 39.64%. [6] Other 2024 reports place the average even lower; an analysis by Oddball Marketing cites a 37.72% average open rate, while Sopro.io reports an average of 35.9%. [8, 9] The 45% open rate is particularly strong when compared to benchmarks specifically for cold outreach, which can be much lower. The Tolly campaign's performance also included an 8.28% reply rate (14 replies from 169 contacts), which is a strong result when typical cold email reply rates range from just 1% to 5%. [23, 15] While high open rates are sometimes inflated by privacy features like Apple's Mail Privacy Protection, the combination of a high open rate with a strong reply and conversion rate indicates genuine engagement. [18]
Remarkably, the campaign's high engagement rates were achieved without a preliminary email warming period, a standard practice that can take four to six weeks. [23, 16] Email warm-up is the process of gradually increasing sending volume from a new or dormant domain to build a positive sender reputation with providers like Gmail and Outlook. [22] Skipping this step typically results in severe consequences, including emails landing directly in spam folders, near-zero open rates, and long-term domain reputation damage that is difficult to repair. [5] The fact that the Tolly campaign could launch on a new domain, complete onboarding, and begin outreach within a single week while still achieving 94% deliverability and high engagement is a significant methodological detail. [23] While some reports indicate that Apollo discontinued its built-in warm-up feature in 2024, requiring users to handle it externally, the Tolly study's results suggest the platform's core infrastructure and data verification processes can mitigate the risks of an abbreviated ramp-up period. [26, 27]
The strong performance metrics from the Tolly study stand out against a backdrop of declining general engagement. For instance, the average B2B cold email reply rate dropped from 5.1% in 2024 to 3.43% in 2026, according to an analysis of over 20 million emails. [20] In this environment, a good reply rate is considered anything from 5-10%. [11] The Tolly campaign's 8.28% reply rate (14 replies from 169 contacts) fits squarely within this 'good' range. [23] Furthermore, the average click-through rate (CTR) for B2B emails sits between 2.0% and 4.0%, with some 2024 reports showing an overall average as low as 2.00%. [4, 8] While the Tolly report focused on meetings booked rather than clicks, the high conversion rate implies that the engagement was not just superficial. The data suggests that while average performance is decreasing due to inbox saturation and stricter spam enforcement, high-performing campaigns that leverage precise targeting and high-quality data can still produce exceptional results.

How Does Cold Calling Compare as a Prospecting Channel in 2024?
Phone outreach maintains its strategic importance as a primary channel for direct human connection, a critical factor in high-value B2B sales cycles. While digital channels offer scale, the immediacy of a conversation remains uniquely effective for engaging senior decision-makers. According to a 2026 analysis by Peak Sales Recruiting, 57% of C-level and VP-level buyers state a preference for phone contact when evaluating complex professional services, underscoring the channel's role in substantive discussions. [8] This preference translates directly into pipeline opportunities; research cited by B2B marketing experts in 2024 confirms that 82% of business buyers have accepted meetings with salespeople following a series of contacts that originated with a cold call. [20] This data from the RAIN Group study highlights that a well-executed call does more than just transmit information, it accelerates relationship-building and provides the instant feedback necessary to navigate complex sales. In an environment saturated with automated emails, the ability to establish a personal connection and have a real-time dialogue is a significant competitive differentiator, making calling an indispensable part of a modern, multi-channel prospecting strategy.
Modern sales engagement platforms directly address the need for efficient calling by embedding sophisticated dialers within the sales representative's workflow. The Apollo.io platform, for instance, integrates its core dialing functions starting with its Professional plan, which a 2026 CloudTalk analysis notes is priced from $79 per user per month. [4] This tier unlocks the platform's domestic auto-dialer and call recording features, enabling teams to move beyond manual dialing. For organizations focused on maximizing call volume, Apollo introduced a native parallel dialer in 2025, a feature that allows a single representative to dial up to five prospect numbers simultaneously and automatically connects them to the first person who answers. This high-efficiency tool, as detailed in a 2026 analysis by TitanX, is designed to dramatically reduce the time spent on unanswered calls and navigating voicemail systems. By gating these advanced tools to its higher-tier Professional and Organization plans, Apollo positions its dialer not as a basic utility but as a strategic asset for teams serious about increasing live conversations and accelerating pipeline velocity. [4, 10]
A high volume of calling activity directly correlates with increased prospect engagement and deeper customer understanding. A 2024 analysis of B2B sales activity metrics published by Databox revealed that high-performing teams demonstrated significant engagement levels, averaging a total of 102.5 calls and 63 meetings for the period analyzed. [9] The report explicitly links this level of activity to more effective relationship building and a more profound comprehension of customer needs. These direct human interactions are invaluable for tasks that automated systems cannot replicate, such as dynamically handling nuanced objections, pivoting a conversation based on real-time feedback, and uncovering latent needs that prospects may not articulate in an email. While email provides an efficient and scalable method for initial outreach, the phone call serves as the crucial next step for qualifying interest and building the rapport necessary to close complex deals. The data from the B2B Sales Benchmarks for 2024 report reinforces that the true value of calling in 2024 lies in its power to foster genuine connection and gather qualitative insights that drive sales cycles forward. [9]
Social Selling: LinkedIn's Dominance in B2B Lead Generation
LinkedIn solidifies its position as the indispensable channel for B2B social selling in 2024, responsible for generating an overwhelming 80% of all B2B leads sourced from social media. [1, 2] This dominance is not accidental; it is the direct result of the platform's professional-centric design, which now hosts over 1.3 billion members and 69 million companies globally. [7, 14] Unlike other platforms built for personal connection, LinkedIn's ecosystem is purpose-built for business networking, industry-specific content distribution, and career development. A 2025 analysis from Content Marketing Institute, which surveyed 980 B2B marketers, found that 85% named LinkedIn as the social platform delivering the best value, a figure dramatically higher than Facebook at 28%. [14] This effectiveness is further highlighted by data showing that four out of five members on the platform actively drive business decisions, making it a fertile ground for prospecting and lead generation activities that connect directly with buying power. [7] The platform's sophisticated advertising tools, including precise targeting by job title, industry, and company size, allow marketers to execute highly focused campaigns, with 89% of B2B marketers leveraging the platform specifically for lead generation. [4]
The platform's superiority extends to user engagement, a critical factor for nurturing leads and building brand authority. A 2026 benchmark analysis from Socialinsider, which studied 1.3 million posts, revealed that the average engagement rate on LinkedIn reached 5.20%, an 8% year-over-year increase. [14] This figure significantly outpaces the typical engagement seen on other major platforms. For instance, a 2024 report from Sprout Social noted that brands receive an average of 22 engagements per day on Facebook and Instagram, compared to 13 on X, indicating a more passive user experience. [16] On LinkedIn, however, the context of professional development and industry insight fosters more substantive interactions. Data from Hashmeta's 2025 analysis shows that users spend an average of 2-3 minutes engaging with relevant business content on LinkedIn, a stark contrast to the 30-45 seconds spent on other social platforms, allowing for more complex B2B value propositions to be communicated effectively. [10] This extended attention is why LinkedIn is 277% more effective for lead generation than Facebook and X, translating directly into higher quality interactions and a more efficient sales funnel. [7]
A crucial element of social selling's success is its direct influence on the B2B buyer's journey, where decision-makers increasingly conduct independent research. Data from 2021 shows that a significant 84% of C-level executives use social media as a source when making purchasing decisions, a trend that has only accelerated. [19] The modern B2B buyer consumes an average of 13 content pieces before finalizing a decision, and platforms like LinkedIn are primary venues for this research. [4] According to the 2024 Edelman-LinkedIn B2B Thought Leadership Impact Report, thought leadership has become the third most important driver for B2B purchase decisions, underscoring the value of expert-led content shared on professional networks. [6] This shift means that a strong, credible presence on LinkedIn is no longer optional; it is a fundamental component of being considered during the buyer's evaluation phase. In fact, 71% of all decision-makers report that social media is influential when they are researching or considering a new product for their company, making it a critical touchpoint long before any direct sales outreach occurs. [20]
Despite LinkedIn's proven effectiveness, a surprising gap exists between its potential and its prioritization by marketing teams. While 89% of B2B marketers use the platform for lead generation, only 44% identify it as their most significant social network, suggesting a considerable opportunity for growth and strategic focus. [4, 14] This discrepancy is further highlighted in broader marketing channel assessments. For example, a 2025 HubSpot State of Marketing Report identified a brand's website, blog, and SEO efforts as the top channel for B2B ROI, followed by paid social media. [3] The challenge often lies in resource allocation and the ability to consistently produce high-quality, engaging content. Hootsuite's Social Trends 2024 report found that 58% of marketers struggle to keep up with new platform features, leading many to prioritize channels based on perceived ROI rather than untapped potential. [17] For organizations willing to invest in a dedicated social selling strategy, including robust content creation and employee advocacy programs, this gap represents a clear competitive advantage waiting to be exploited.
2024 B2B Prospecting Channel Performance Comparison
Email prospecting performance in 2024 reveals a significant gap between high-performing platforms and general industry benchmarks, underscoring the impact of targeted execution. The independent 2024 Tolly Group study found that a cold email campaign on the Apollo.io platform achieved a 45% open rate and a 2.37% meeting booked rate, metrics that substantially outperform typical results. For comparison, the average B2B open rate is approximately 32%, with some analyses suggesting it can be as low as 27.7%. [5, 16] The disparity is even more pronounced when examining meeting conversion, where the industry average is estimated between 0.5% and 1.5%, making the Apollo campaign's performance more than double the lower-end benchmark. This performance delta is often attributed to the quality of contact data and the sophistication of the outreach platform. For instance, reports like the Salesforce State of Sales 6th Edition (2024) emphasize that sales teams are increasingly turning to AI-driven platforms to enhance productivity and personalization, which directly influences engagement outcomes. [8, 21] The success of specialized platforms demonstrates that while email remains a core channel, its effectiveness is highly dependent on the technology and data quality underpinning the campaign, moving beyond simple volume-based approaches.
Social media prospecting is overwhelmingly dominated by a single platform, with LinkedIn accounting for 80% of all B2B leads generated through social channels. [1, 5] This concentration highlights the platform's critical role in modern B2B outreach strategies, where professionals gather to network and consume professionally relevant content. The average engagement rate on LinkedIn is around 2%, a figure that includes likes, comments, and shares. [5] However, this metric doesn't directly translate to booked meetings and represents a different type of interaction compared to email's direct response goals. According to the 2024 Edelman-LinkedIn B2B Thought Leadership Impact Report, decision-makers actively use thought leadership content on the platform to vet and evaluate potential vendors, making a strong presence a crucial, top-of-funnel activity. [13] While the 2% engagement rate seems modest, its value lies in building brand credibility and nurturing prospects over time, positioning it as a complementary channel to more direct methods like email and phone calls. The platform's effectiveness is less about immediate conversion and more about creating the context and trust necessary for those conversions to happen elsewhere.
Success in phone-based prospecting is fundamentally a game of volume and persistence, with benchmarks indicating that high activity is non-negotiable for securing meetings. While direct meeting conversion rates per call can be low, industry analyses from firms like Gong and Cognism reveal the interconnectedness of calling with other channels. For example, one analysis of over 300 million calls found that cold calling nearly doubles email reply rates, even if the call itself doesn't connect. [18] This suggests the primary value of a call attempt is often brand recall and multi-channel reinforcement. Activity benchmarks from organizations like The Bridge Group and Operatix suggest that top-performing sales development representatives make 40-50 calls per day, part of a broader strategy of 80-100 total daily activities. [9] Furthermore, data from Cognism's 2024 State of Cold Calling Report, which analyzed over 9,000 outbound calls, found an average success rate of 4.82% for converting a live conversation into a booked meeting. [26] This highlights that while it may take significant effort to get a prospect on the phone, the conversation itself has a reasonable chance of success, justifying the high-volume approach required for this channel.
