23 Email Marketing Tips to Improve Open & Clickthrough Rates [+HubSpot Blog Data]

Email marketing is not dead. It is not even taking a nap. It is wide awake, sipping coffee, and quietly producing revenue while flashier channels argue over algorithms. But here is the catch: inboxes are crowded, privacy changes have made open rates harder to trust, and subscribers can smell lazy marketing faster than a dog detects peanut butter.

Improving email open rates and clickthrough rates is no longer about sending more emails. It is about sending better emails to the right people, at the right moment, with a message that feels useful instead of interruptive. HubSpot’s email marketing guidance emphasizes a simple truth: strong campaigns are built from consent, relevance, testing, deliverability, and disciplined measurement. That may sound less glamorous than “secret growth hack,” but it works better and requires fewer smoke machines.

This guide breaks down 23 practical email marketing tips that help improve open rates, click-through rates, click-to-open rates, and overall campaign performance. You will also find real-world examples, analysis, and a hands-on experience section at the end for marketers who want advice that survives contact with actual subscribers.

Why Open Rates and Clickthrough Rates Still Matter

Open rate tells you whether your sender name, subject line, preview text, timing, and deliverability are doing their job. Clickthrough rate tells you whether the email itself made people take action. Both metrics matter, but they should not be worshipped like tiny dashboard gods.

Modern marketers increasingly use open rate as a directional metric because Apple Mail Privacy Protection and image preloading can inflate opens. Clicks, conversions, revenue per email, bounce rate, unsubscribe rate, and complaint rate give a more complete view of performance. In plain English: opens show interest, clicks show intent, and conversions show whether the whole thing paid rent.

23 Email Marketing Tips to Improve Open and Clickthrough Rates

1. Never Buy Email Lists

Buying an email list feels like a shortcut until it becomes a scenic route to the spam folder. Purchased contacts did not ask to hear from you, so they are less likely to open, click, trust, or buy. Worse, they may mark your email as spam, damaging your sender reputation.

Grow your list through opt-in forms, lead magnets, webinars, checkout signups, newsletter subscriptions, and useful gated content. A smaller list of interested subscribers will outperform a giant list of strangers who are wondering how you got their address.

2. Follow CAN-SPAM and Email Compliance Rules

Compliance is not the thrilling part of email marketing, but neither is getting fined. Commercial emails should include accurate sender information, a valid physical mailing address, a clear unsubscribe option, and honest subject lines.

Do not pretend an email is a personal note when it is a promotion. Do not hide the unsubscribe link in microscopic gray text. Respecting subscribers is not only legally smart; it also improves trust, which improves engagement.

3. Use Clear Permission-Based Opt-Ins

Permission is the foundation of healthy email performance. If subscribers actively choose to hear from you, they are more likely to recognize your brand in the inbox and engage with your content.

Use simple signup language that explains what people will receive and how often. For example: “Get one practical ecommerce growth tip every Tuesday” is much clearer than “Join our mailing list,” which sounds like entering a storage closet with Wi-Fi.

4. Send a Welcome Email Within 24 Hours

The best time to email a new subscriber is when they still remember subscribing. A welcome email sent quickly can confirm the signup, deliver the promised resource, introduce your brand voice, and guide the reader toward the next action.

For example, a software company might send: “Your free reporting template is here” with one button: “Download the template.” Simple, timely, useful. That is the email equivalent of showing up with snacks.

5. Send From a Real Person

A human sender name often feels more approachable than a generic company address. “Maya from BrightCRM” usually feels warmer than “Marketing Department.” Test both, because brand recognition can matter too.

For B2B campaigns, a hybrid sender name often works well: “Alex at FinOps Weekly.” It feels personal while still reminding the recipient why the email exists.

6. Optimize Preview Text

Preview text is the short snippet that appears beside or below the subject line in many inboxes. If you ignore it, email clients may display awkward default text like “View this email in your browser,” which is not exactly poetry.

Use preview text as a second hook. If the subject line is “Your abandoned cart is getting lonely,” the preview text might be “Come back today and shipping is on us.” Together, they create context and curiosity.

7. Write Clear, Clickable Subject Lines

Subject lines should be specific, relevant, and easy to understand. Clever is fine; confusing is expensive. A good subject line tells the reader why opening the email is worth their time.

Strong examples include “Your Q3 benchmark report is ready,” “3 mistakes slowing your sales pipeline,” or “Last chance to save your seat.” Weak examples include “Newsletter #47” and “Important update,” the email equivalent of beige wallpaper.

8. Keep Emails Focused and Concise

Email is usually scanned, not studied. Get to the point quickly. Use short paragraphs, clear headings, and one main idea per email. If readers need hiking boots to reach your call to action, the email is too long.

Long-form newsletters can work when the audience expects depth, but promotional emails should generally be lean. Say what matters, show the value, and make the next step obvious.

9. Use One Primary Call to Action

One email should usually have one main job. Download the guide. Register for the webinar. Shop the sale. Book the demo. When you ask readers to do five things, many will do the sixth thing: leave.

A single primary CTA improves clickthrough rates because it reduces decision fatigue. Supporting links are fine, especially in newsletters, but the main action should be visually dominant.

10. Make CTA Buttons Action-Oriented

Button copy should finish the sentence “I want to…” Instead of “Submit,” try “Get My Free Checklist.” Instead of “Click Here,” try “Reserve My Seat.” The reader should know exactly what happens after the click.

Good CTA copy is specific, benefit-driven, and low-friction. It does not need jazz hands. It needs clarity.

11. Add Alt Text to CTA Images

Some email clients block images by default. If your CTA exists only as an image, part of your audience may see a blank space where your conversion opportunity should be. That is tragic, but in a very technical way.

Use descriptive alt text such as “Download the free email calendar” or “Shop the new summer collection.” This helps accessibility and preserves meaning when images do not load.

12. Link Your Images

People naturally click images. Product photos, ebook covers, event banners, and hero graphics should usually link to the same destination as your primary CTA.

This simple habit can improve clickthrough rates without adding clutter. If the image sells the offer, let it open the door.

13. Include Noticeable Text Links

Do not rely only on buttons. Some readers prefer clicking inline links while scanning. Add one or two natural text links where they make sense, especially near the value proposition.

For example: “See the full benchmark report” can appear in the body copy before the button. More clickable entry points can create more engagement, as long as they support the same main goal.

14. Place a Clickable Element Above the Fold

Many subscribers will not scroll. Put a CTA button, text link, or clickable image near the top of the email so the action is visible quickly, especially on mobile screens.

This does not mean shoving a giant “BUY NOW” button into line one like an overeager salesperson. It means making the next step available before attention fades.

15. Avoid Overly Complex Background Images

Email clients do not render designs consistently. Background images can break, disappear, or turn a beautiful design into a mysterious blank rectangle. Outlook, in particular, has historically been picky about background image support.

Use solid background colors and inline images when possible. Design for reliability first, then decoration. An email that renders correctly is better than an email that wins an art award in only two inboxes.

16. Add Social Sharing When It Supports the Goal

If your email promotes a useful guide, report, article, event, or campaign, social sharing buttons can extend its reach. This works especially well for content that helps the reader look smart when they share it.

Keep sharing options limited. Too many icons can create visual noise. Choose the platforms your audience actually uses.

17. Create Pre-Written Share Copy

If you want people to share your content, make it easy. A pre-written social post or share link removes friction and increases the odds that a reader will pass along your resource.

For example, after promoting a benchmark report, include: “Know a teammate who tracks email performance? Share this report with them.” A gentle nudge often works better than pretending sharing will happen by telepathy.

18. Add a Forward-to-a-Friend Prompt

Email forwarding is underrated. A simple line like “If this would help someone on your team, forward it their way” can increase organic reach.

This works best for newsletters, industry insights, checklists, templates, and educational content. People forward things that make them useful to others. Help them be the hero with the good link.

19. Clean Up Plain-Text Versions

Every HTML email should have a readable plain-text version. If the plain-text version is messy, packed with raw URLs, or full of broken formatting, it can hurt user experience and deliverability.

Before sending, review the plain-text email. Make sure the message still makes sense, links are clear, and the CTA is easy to find.

20. Optimize for Mobile Readers

Mobile optimization is not optional. Use responsive templates, large readable fonts, short subject lines, tappable buttons, compressed images, and single-column layouts. A CTA button should be easy to tap with a thumb, not require the precision of a jewel thief.

Preview every email on mobile before sending. A campaign that looks beautiful on a desktop monitor may become a formatting jungle on a phone.

21. Test Before Every Send

Send test emails to yourself and your team. Check the subject line, preview text, links, images, personalization tokens, mobile rendering, dark mode behavior, and unsubscribe link.

Broken links are silent conversion killers. A five-minute test can save a campaign from becoming a very well-designed dead end.

22. Clean Your Contact List Regularly

A healthy email list beats a bloated one. Inactive subscribers, invalid addresses, role-based emails, and spam traps can damage deliverability and distort performance data.

Create re-engagement campaigns for inactive contacts. If they still do not respond, suppress or remove them. List hygiene may feel scary because the number gets smaller, but your engagement rate and inbox placement often improve.

23. Monitor Performance and A/B Test One Variable at a Time

Improvement comes from testing, not guessing. Track open rate, click rate, click-to-open rate, conversion rate, bounce rate, unsubscribe rate, complaint rate, revenue per email, and performance by segment.

Test one variable at a time: subject line, sender name, CTA copy, CTA placement, send time, offer angle, image style, or email length. If you change everything at once, you may get a result, but you will not know why. That is not science; that is confetti.

Deliverability: The Quiet Hero Behind Better Opens

You cannot improve open rates if your emails never reach the inbox. Deliverability depends on sender reputation, authentication, list quality, engagement, and complaint rates. Gmail and Yahoo have made authentication especially important for bulk senders, including SPF, DKIM, and DMARC alignment, along with easy unsubscribe options and low spam complaint rates.

Set up SPF to show which servers can send for your domain. Use DKIM to prove the message was not altered. Publish a DMARC policy to tell receiving servers how to handle unauthenticated mail. These technical steps may not sound exciting, but they are the plumbing of email marketing. Nobody praises plumbing until it fails.

How to Improve Clickthrough Rates After the Open

Once someone opens your email, the subject line has done its job. Now the content must earn the click. The fastest way to improve clickthrough rates is to align the email with one audience, one problem, one promise, and one action.

For example, a generic email might say, “Check out our latest solutions.” A stronger email says, “Reduce abandoned carts before the weekend rush” and then points to a short checklist. The second version wins because it speaks to a real situation and offers a clear next step.

Use segmentation to make that relevance easier. New subscribers may need education. Existing customers may need upgrade ideas. Dormant leads may need a re-engagement offer. Loyal buyers may appreciate early access. When everyone receives the same message, the email has to be vague. When each segment receives a tailored message, the email can be useful.

Benchmarks: What Counts as “Good”?

Email benchmarks vary by industry, list quality, audience source, send frequency, and platform. Some sources report average open rates in the 20% to 40% range, while average click rates often land around 2% to 5%. Mailchimp benchmark data places optimal campaign CTR around 2.66%, while other platforms show differences by vertical and campaign type.

Use benchmarks as a compass, not a courtroom verdict. A 2.5% click rate might be excellent for a cold nurture list and disappointing for a highly engaged customer segment. The better comparison is your own historical performance by audience and campaign type.

Common Email Marketing Mistakes That Hurt Opens and Clicks

Sending Too Often Without Adding Value

If every email is a promotion, subscribers learn to ignore you. Mix offers with education, insights, tools, stories, and useful reminders. Earn attention between sales pushes.

Using Vague Subject Lines

“A quick update” does not tell readers why they should care. Specificity wins. “Your June analytics checklist” is more useful and more clickable.

Making the CTA Hard to Find

If readers have to hunt for the next step, many will give up. Use clear buttons, visible links, and simple layouts.

Ignoring Inactive Subscribers

Inactive contacts lower engagement and can hurt deliverability. Build a re-engagement workflow and suppress contacts who remain cold.

Practical Experience: What Actually Works in Real Email Campaigns

In real email marketing work, the biggest improvements rarely come from one dramatic change. They come from small adjustments stacked consistently over time. The best-performing teams usually have a boring but powerful rhythm: plan, segment, write, test, send, measure, learn, and repeat. It is not glamorous, but neither is brushing your teeth, and look how important that turned out to be.

One experience that comes up often is the “high opens, low clicks” problem. A campaign may have a subject line that creates curiosity, but the email body fails to deliver a strong reason to act. For example, a subject line like “This changes everything” may get opens, but if the email leads to a generic product announcement, readers feel tricked. The fix is alignment. The subject line, preview text, opening sentence, CTA, and landing page should all tell the same story.

Another common lesson is that segmentation almost always beats cleverness. A beautifully written email sent to the wrong audience will underperform a simple, direct email sent to people who actually need the offer. For instance, a marketing agency promoting a “local SEO checklist” should not send the same message to ecommerce brands, SaaS founders, restaurant owners, and enterprise CMOs. The restaurant owner may care about Google Business Profile visibility. The SaaS founder may care about review snippets and branded search. The offer can remain similar, but the angle should change.

Testing subject lines is useful, but testing offers is often more useful. Many teams obsess over whether the subject line should include an emoji, a number, or a question. Those details can matter, but the bigger question is whether the email contains something worth clicking. A weak offer with a clever subject line is still a weak offer wearing a tiny hat.

In ecommerce campaigns, urgency works best when it is real. “Sale ends tonight” can drive clicks if the sale actually ends tonight. If every email screams urgency, subscribers become immune. A better approach is to combine relevance with timing: replenishment reminders, back-in-stock alerts, price-drop notifications, loyalty rewards, and abandoned cart emails. These feel useful because they are based on behavior.

For B2B campaigns, educational value often beats aggressive selling. A helpful benchmark report, calculator, template, or teardown can generate stronger clicks than a direct “Book a demo” email, especially early in the buyer journey. Once readers engage with educational content, follow-up emails can introduce a consultation, product tour, or case study. This creates a smoother path from curiosity to conversion.

List hygiene also creates surprising gains. Many marketers resist removing inactive contacts because a big list feels impressive. But a large, disengaged list is like a crowded room where most people are facing the wall. Suppressing inactive subscribers can improve engagement signals, reduce spam risk, and make reporting more honest. It is better to email 20,000 people who care than 80,000 people who forgot you exist during the previous presidential administration.

The most reliable lesson is this: email marketing improves when you stop treating campaigns as isolated events. Every send should teach you something. Which segment clicked? Which CTA worked? Which topic caused unsubscribes? Which email led to revenue, not just opens? When your team documents these answers, your email program becomes smarter each month.

Finally, the best email marketers protect trust like it is a budget line item. They do not trick people into opening. They do not hide unsubscribe links. They do not send irrelevant blasts because “we need one more campaign this week.” They understand that better open rates and clickthrough rates are the result of being consistently useful. The inbox is personal space. Treat it with respect, and subscribers are far more likely to welcome you back.

Conclusion

Improving email open rates and clickthrough rates is not about chasing one magic tactic. It is about building a better email system: permission-based lists, strong deliverability, human sender names, clear subject lines, useful preview text, mobile-friendly design, focused CTAs, accessible formatting, smart segmentation, regular testing, and honest performance analysis.

HubSpot’s email marketing data and broader industry benchmarks point in the same direction: relevance wins. The brands that earn opens and clicks are not always the loudest. They are the clearest, most helpful, and most consistent. Write for real people, test like a scientist, clean your list like a responsible adult, and remember that every email is a tiny trust exercise. Do that well, and your open and clickthrough rates will have a much better chance of moving in the right direction.
