Email marketing is an effective way for therapists to connect with clients and grow their practice. To improve results, it’s essential to track these five key email metrics:
- Open Rate: Measures how many recipients open your emails. Aim for 24.5% or higher for mental health practices.
- Click-Through Rate (CTR): Tracks the percentage of recipients clicking links in your email. A healthy CTR for the industry is around 2.8%.
- Conversion Rate: Shows how many recipients complete a desired action, like booking a session. Strong campaigns can achieve up to 10%.
- Bounce Rate: Reflects emails that fail to reach recipients. Keep this under 2% to maintain deliverability.
- Unsubscribe Rate: Indicates how many opt-out after receiving your email. Stay below 0.5% to keep your list engaged.
Tracking these metrics helps you adjust your strategy, improve engagement, and drive more client bookings. Simple changes like better subject lines, clear calls-to-action, and regular list cleaning can make a big difference.
5 Email Metrics Therapists Should Track: Benchmarks & Goals
Should Therapist Use Email Lists to Connect to Potential Clients?
1. Open Rate
Open rate tells you the percentage of subscribers who actually open your email. It’s a critical first step in gauging whether your message is resonating – are people curious enough to take a look?
For therapists, the mental health industry average open rate is 24.5%, while the broader health and wellness sector sees a higher rate of 34.94%. Welcome emails, in particular, perform exceptionally well, with mental health practices achieving open rates around 48% – nearly double the industry norm. If your regular newsletters are consistently falling below 25%, it’s a sign you might need to tweak elements like your subject line, sender name, or even the quality of your email list. These adjustments can have a ripple effect on the success of your entire email strategy.
Your subject line is a major driver of engagement. Compare "Monthly Newsletter – June" to something like "The one question that changes how couples argue" – the latter sparks curiosity and invites clicks. Adding personalization, such as the recipient’s first name, can boost open rates by 26%. And keep subject lines under 50 characters to ensure they display fully, especially since 62% of emails are opened on mobile devices.
There’s also a technical side to consider. Apple’s Mail Privacy Protection (MPP) pre-loads tracking pixels, which can inflate open rates by as much as 15–25 percentage points. Thomas Oakes from Referral Program Pros explains:
"Open rate is still useful as a trend metric, but not as an absolute one… The exact number is less meaningful because it’s so polluted by automated opens."
To address this, most email platforms like ActiveCampaign or HubSpot offer a feature to filter out bot and MPP-related opens. Enabling this filter will lower your reported open rate, but the data you get will be far more accurate – helping you make better decisions for your campaigns.
2. Click-Through Rate (CTR)
Once you’ve figured out who opens your emails, the next step is identifying who takes action by clicking on your links. If the open rate shows who noticed your email, the CTR reveals who was genuinely interested. This metric calculates the percentage of recipients who clicked on a link within your email, and it offers a more accurate picture of engagement since it’s unaffected by Apple’s Mail Privacy Protection. As Courier Media explains:
"Click rate is a much more reliable measure of actual engagement than open rate because it requires a human to actually interact with the content. Apple can’t fake a click."
For therapists, the average CTR in the mental health industry is 2.8%, while general healthcare services hover around 2.70%. Newsletters, however, tend to lag behind with an average CTR of 1.9%. This is because newsletters often lack a clear next step, unlike action-driven emails like appointment reminders or downloadable resources, which tend to perform much better in this regard.
One common reason for low CTRs is unclear calls-to-action (CTAs). Generic phrases like "Click Here" or "Read More" don’t inspire action. Specificity is key – something like "Download the anxiety worksheet" or "Book a free 15-minute call" clearly communicates the value to the reader. As Courier Media points out: "If your open rate looks fine but your click rate is low, the problem is in the email body, not the subject line." In short, a low CTR usually signals issues with your email content or CTAs rather than with getting people to open the email.
Here are a few practical ways to boost your CTR:
- Position your most important link near the top of the email, and repeat your primary CTA in the P.S. section – one of the most-read parts of any email.
- Include 2 to 5 links per email to provide options without overwhelming the reader.
- Use segmented campaigns. Targeted emails see click rates that are 267.21% higher than non-targeted ones.
Making these changes can help turn passive readers into active participants.
3. Conversion Rate
If click-through rate (CTR) tells you who clicked, conversion rate answers the next big question: Who took action? It measures the percentage of recipients who clicked a link and then completed a desired action – whether that’s booking a consultation, signing up for a free call, or downloading a resource. In other words, it’s the clearest sign of whether your emails are driving meaningful outcomes for your practice.
In the Health & Wellness industry, conversion rates typically range from 1% to 5%. However, mental health campaigns with strong engagement and trust can achieve rates as high as 10%. These benchmarks give therapists a clear target for optimizing their email campaigns to grow their practice effectively. As Koppla Marketing explains:
"The journey to seeking therapy rarely follows a ‘visit website → book now’ path. Instead, it’s a gradual process of trust-building, self-discovery, and readiness."
One strategy that consistently boosts conversion rates is automated email sequences. These perform four times better than standard one-off campaigns. For instance, a 3–5 email welcome sequence gives new subscribers the time and space to warm up before committing to an action. Stressless Digital Marketing Agency highlights this dynamic perfectly:
"The conversion that happens at the end of a trust-first email sequence is a different quality of yes."
To improve your conversion rates, focus on reducing friction. Make sure your email links take readers directly to a simple booking page – not a homepage or a busy contact form. Adding UTM parameters (tracking tags) to your links can help you pinpoint which campaign drove the action. Lastly, keep your emails focused. As psychologist and business coach Nicole McCance advises:
"One email = one clear call to action. Too many options creates distraction."

4. Bounce Rate and List Health
Email deliverability doesn’t just depend on engagement – it also relies heavily on keeping your email list in good shape. One key metric to watch is your bounce rate, which measures the percentage of emails that fail to reach recipients. These failures fall into two categories: hard bounces and soft bounces.
- Hard bounces happen when an email address is invalid or permanently unavailable (e.g., deleted accounts). These should be removed from your list immediately.
- Soft bounces are temporary issues, like a full inbox. If an email address experiences three soft bounces in a row, treat it as a hard bounce and remove it.
A bounce rate below 2% is considered healthy, while anything above 5% can signal trouble. High bounce rates can lead email providers to throttle or even suspend your account. For instance, in the healthcare industry, the average bounce rate hovers around 2.5%, but poorly maintained lists can see rates as high as 10.12%. That’s a clear warning sign of deliverability issues.
As Mailfloss explains:
"Sender reputation is like a credit score for your email domain. Every time you send to a bounced email address… your score drops."
When your sender reputation takes a hit, email providers like Gmail or Outlook are more likely to send your emails straight to the spam folder. With stricter spam regulations and authentication protocols in place, keeping your bounce rate low is more important than ever.
The best way to tackle this problem is to address it right at the source. Implementing double opt-in ensures that subscribers confirm their email ownership. Adding a real-time verification tool to your signup form can catch common typos – like "gmial.com" – before they even make it onto your list. Beyond that, a thorough cleanup of your email list every 90 days is essential. Email lists naturally degrade over time, with up to 30% of addresses becoming invalid each year as people switch jobs or abandon old inboxes.
As SyncGTM‘s Kushal Magar aptly puts it:
"List hygiene is not a project – it is ongoing infrastructure."
Regularly maintaining your email list not only helps reduce bounce rates but also ensures the accuracy and reliability of all your email performance metrics.
5. Unsubscribe Rate and List Engagement
The unsubscribe rate reflects the percentage of recipients who choose to opt out after receiving one of your emails. For therapy practices, the goal is clear: keep this number under 0.5% per email sent. In fact, the 2026 average for the mental health sector sits at 0.25%. If your rate starts edging above that, it’s a sign to reassess your approach.
Common culprits include sending too many emails or relying on generic, impersonal content. Psychologist and business coach Nicole McCance puts it simply:
"I avoid the word ‘newsletter’ because people ignore newsletters. But what they DO want are tools that help them feel better."
This insight underscores the importance of tailoring your emails to address specific concerns your audience cares about – like managing stress or improving sleep – rather than just sharing routine updates. Sticking to a manageable frequency, such as 2 to 4 emails per month, can also help maintain interest and reduce opt-outs.
Another effective strategy is segmentation. By dividing your list into categories – such as new leads, current clients, and past clients – you can send content that resonates with their unique needs. Sending the same message to everyone often leads to higher unsubscribe rates, whereas targeted content improves engagement and reduces opt-outs. This approach doesn’t just lower unsubscribe rates; it also boosts the overall success of your campaigns and aligns with your practice’s growth objectives.
Remember, a smaller, engaged list is far more effective than a large, disengaged one. For instance, 500 active subscribers will drive more results than 5,000 who never interact with your emails. As Mental Health Marketing explains:
"While it feels counterintuitive to shrink your list, inactive subscribers hurt your open rates and sender reputation without providing any benefit."
The key is to focus on quality over quantity. Keeping an eye on these metrics ensures your email strategy remains a valuable tool for growing your practice.
How Email Metrics Connect to Practice Growth with Humanly
Email metrics can guide smarter decisions for your practice every day. By analyzing your subscribers’ interests, you gain a clearer sense of demand trends. This helps you plan schedules more effectively and manage resources for flexible practice spaces.
For therapists using Humanly’s on-demand spaces, these insights are especially practical. Humanly’s flexible spaces make it easy to act on email data. For instance, if click-through rates spike on anxiety-related content in September – a time when back-to-school stress is common – you can proactively reserve more hourly or part-time space. This ensures availability when demand peaks, rather than scrambling at the last minute. On the flip side, during slower months, you can scale back and book only what you need, keeping costs down.
Email metrics also take the guesswork out of testing new services. Before committing to a recurring schedule or launching a new specialty, you can send an email with a "Coming Soon" link or an interest form. Monitoring the response is key – a click-through rate between 2% and 5% can be a strong indicator to proceed. Whether it’s booking a group room at Humanly for a workshop or adding more individual session slots, this data-driven approach reduces risk.
"The metrics that truly matter are the ones that connect to practice growth… These downstream metrics tell you whether your email marketing is actually contributing to revenue, not just generating opens." – Mental Health Marketing
Automation takes this efficiency even further. Automated welcome and nurture sequences can achieve open rates as high as 42.1% and convert four times better than manual campaigns. This means your email list works in the background, building trust and nurturing leads while you focus on your clinical work. By the time someone books a consultation, much of the groundwork has already been laid.
"This single practice of monthly metric review puts you ahead of the vast majority of therapy practices that make marketing decisions on intuition alone." – Mental Health Marketing
Conclusion
Let’s tie it all together: tracking and analyzing key metrics like open rate, click-through rate, conversion rate, bounce rate, and unsubscribe rate can turn your email list into a powerful tool for growth. Each metric reveals something important – whether your subject lines grab attention, your content resonates, or your audience is ready to take action.
For example, improving your open rate by just 5% can increase readership by 20%. Over time, that kind of improvement can lead to more inquiries, more bookings, and a more stable practice. These metrics don’t just measure performance – they guide your strategy, helping you fine-tune your approach to achieve better results.

FAQs
Which email metric matters most for getting new client bookings?
The conversion rate stands out as the key metric for securing new client bookings. While open rates and click-through rates measure engagement, the conversion rate goes a step further – it tracks the percentage of recipients who follow through on a specific action, such as scheduling a consultation. Keeping an eye on this metric helps you understand how well your emails are converting subscribers into paying clients. Humanly is here to support your practice with adaptable, fully equipped therapy spaces tailored for wellness professionals.
How can I track conversions from an email to a booked session?
To monitor conversions effectively, include UTM parameters in your email links. These parameters allow you to track traffic sources in tools like Google Analytics 4. Set up a conversion event by defining a booked session as a visit to a confirmation page.
For more precise tracking, consider implementing server-side tracking. This approach helps link email identifiers to user sessions, even when users switch devices. Regularly review your dashboards to understand which campaigns are generating the most client bookings and driving revenue.
What should I do if my bounce rate suddenly increases?
If you notice a sudden increase in your bounce rate, it’s critical to pause email sending immediately to safeguard your sender reputation. Start by identifying the type of bounce:
- Hard bounces: These occur when emails are sent to invalid or non-existent addresses. These addresses should be removed from your list permanently.
- Soft bounces: These are typically caused by temporary issues like a full inbox or server problems. Retry sending to these addresses for up to 72 hours. If the problem persists, remove them from your list.
Additionally, double-check your email authentication settings, including SPF, DKIM, and DMARC records, to ensure they are correctly configured. It’s also a good idea to monitor your domain’s reputation using tools like Google Postmaster to identify any potential issues.
