Email remains one of the most effective marketing and communication channels available to staffing firms. Whether you’re nurturing client relationships, promoting job opportunities, or re-engaging inactive candidates, email provides a direct line to your audience without relying on changing social media algorithms or paid advertising.
According to Statista, the United States averaged approximately 9.8 billion emails sent daily in 2025, making it the largest email market in the world.1 Despite the growth of social media and other digital channels, email remains a primary communication tool for businesses and professionals alike.
However, sending emails is only part of the equation. Leadership teams need to understand whether their email campaigns are actually delivering results.

Benchmarks That Reveal Your Email Effectiveness
Email marketing benchmarks provide valuable context. While every staffing firm serves different markets and audiences, comparing performance against industry averages can help determine whether your emails are driving engagement or simply getting overlooked.
1. Open Rates Show Whether You’re Earning Attention
Open rates remain one of the most commonly tracked email marketing metrics. For staffing firms, strong open rates often indicate that recipients recognize your brand, trust your communications, and find your subject lines relevant.
Low open rates can signal several issues:
- Subject lines lack relevance
- Email frequency is too high
- Contact lists contain inactive recipients
- Messages are reaching the wrong audience
While open rates should not be viewed in isolation, they provide an important first indicator of whether your audience is paying attention. If recipients are not opening emails, even the most valuable content will fail to generate results.
2. Click-Through Rates Measure Real Engagement
An open does not necessarily mean a reader found value in the email. Click-through rates help staffing firms understand whether recipients are taking action after opening.
For candidate-focused campaigns, clicks may indicate interest in job opportunities, career resources, or application pages. For client-focused communications, clicks often reveal interest in workforce trends, hiring solutions, or staffing services.
This metric has become increasingly important across the marketing industry. Research found that click-through rate remains one of the most important email marketing KPIs used by marketers because it reflects actual engagement rather than simple visibility.2
Strong click-through performance usually reflects a clear message, relevant content, and a compelling call to action.
3. Unsubscribe Rates Reveal Audience Alignment
Every staffing firm experiences unsubscribes, but consistently high unsubscribe rates may indicate a larger problem.
Recipients may feel that:
- Content lacks relevance
- Emails are arriving too frequently
- Messaging feels overly promotional
- Communications fail to match their interests
Monitoring unsubscribe activity can help marketing and leadership teams better understand audience preferences and adjust their communication strategy accordingly.
What Drives Better Open Rates and Engagement
Many staffing firms focus heavily on email volume when results often depend more on relevance, timing, and execution.
1. Strong Subject Lines Create the First Impression
Subject lines determine whether an email gets opened or ignored. Staffing professionals receive hundreds of emails each week, making clarity especially important.
Effective subject lines tend to be:
- Specific
- Concise
- Relevant to the recipient
- Focused on value
Instead of generic messages, successful staffing firms often tailor subject lines based on audience needs, industry trends, hiring challenges, or candidate interests.
2. Segmentation Improves Relevance
Candidates, clients, prospects, and former placements all have different priorities. Sending the same message to every contact often reduces engagement.
Segmented email campaigns allow staffing firms to deliver more targeted communications, increasing the likelihood that recipients find the content useful.
Even simple segmentation strategies can improve performance by ensuring the right people receive the right message at the right time.
3. Consistent Value Builds Trust
The most successful staffing email programs are not built around constant promotion.
Recipients are more likely to engage when emails consistently provide useful information, such as:
- Hiring insights
- Workforce trends
- Career advice
- Industry updates
- Market intelligence
When audiences expect value, engagement naturally improves over time. This helps explain why email continues to perform so well as a business channel. Email marketing proves to be an incredibly cost-effective channel, delivering an average return of $36 for every dollar spent.3 Demonstrating the value of building long-term engagement rather than focusing solely on short-term promotional campaigns.

Quick Wins to Improve Email Performance
Improving email marketing effectiveness does not always require major changes. Small adjustments can often deliver meaningful results.
1. Review Your Subject Line Strategy
Analyze recent campaigns and identify patterns among the highest-performing emails. Look for common themes related to length, wording, and audience relevance.
2. Clean Your Contact Lists Regularly
Inactive contacts can negatively impact engagement metrics. Regular list maintenance helps improve deliverability and provides a more accurate picture of campaign performance.
This is particularly important because deliverability challenges are more common than many organizations realize.
3. Test Before Scaling
A/B testing subject lines, calls to action, send times, and content formats can reveal valuable insights. Small tests often uncover opportunities that significantly improve future campaigns.
4. Focus on Actionable Content
Every email should answer a simple question: Why should the recipient care?
Whether you’re communicating with clients or candidates, useful content tends to outperform purely promotional messaging. Organizations that consistently measure and optimize performance are often rewarded for those efforts.
Turn Benchmarks into Better Results.
Email marketing benchmarks can tell you where you stand, but the real value comes from how you respond to the data. The most effective staffing firms continuously test, refine, and adapt their outreach strategies based on what their audiences actually engage with.
