Email Marketing Best Practices - Boost Open & Click Rates

Email marketing is one of the most powerful and cost-effective tools in digital marketing. Even with the rise of social media, messaging apps, and video content, email still remains a strong channel for connecting directly with your audience. But here’s the catch: it’s not just about sending emails; it’s about getting people to open them, read them, and take action.

If your open rates are low, or your click-through rates aren’t improving, you might need to adjust your strategy. In this article, we’ll walk you through the best practices for email marketing that help boost both open and click rates. Whether you’re a small business owner, a marketer, or a content creator, these tips are easy to follow and very effective.

Why Email Marketing Still Works in 2025

Before we dive into the tactics, let’s quickly understand why email marketing is still relevant.

• Direct access to audience: You land straight into your reader’s inbox.
• High ROI: Email marketing delivers an average return of $36 for every $1 spent.
• Customizable: You can tailor content for different groups of people.
• Easy to track: You can see who opened your emails, clicked your links, and even who unsubscribed.
• Universal reach: Nearly everyone has an email address, making it accessible across all demographics.
• Ownership advantage: Unlike social media platforms, you own your email list and are not affected by algorithm changes.

But none of these matters if your emails don’t get opened or clicked. Let’s fix that.

1. Craft a Subject Line That Gets Attention

The subject line is the first thing your audience sees. If it’s boring, misleading, or too long, people will ignore your email.

Best Practices:

• Keep it short and sweet (40-50 characters or 5-7 words).
• Use action words: “Get,” “Boost,” “Discover,” “Learn.”
• Create curiosity: “You’re Missing Out on This Tip…”
• Use numbers or emojis: “5 Ways to Boost Sales 💰”
• Avoid spammy words like “Buy Now,” “Free!!!,” “Act Immediately.”

A/B Testing Tip:

Test different subject lines on smaller segments of your audience to see which one performs better, then send the best version to the rest.

2. Use a Recognizable “From” Name

People are more likely to open emails from names they recognize. If they don’t know who you are, they’ll ignore the message or mark it as spam.

Best Practices:

• Use your brand name or a person’s name + brand (e.g., Sarah from CleanBeauty).
• Avoid using generic addresses like noreply@domain.com.
• Be consistent with your sender’s name.

3. Write a Strong Preheader Text

The preheader is the text that appears next to or below the subject line in the inbox. It’s your second chance to convince the reader to open.

Best Practices:

• Expand on your subject line: “Limited-time offer—see what’s inside.”
• Keep it under 100 characters.
• Avoid repeating the subject line.

4. Segment Your Email List

Sending the same message to everyone rarely works. Not all subscribers are the same, so treat them differently.

Ways to Segment:

• By location
• By gender
• By past purchases
• By activity level (active vs inactive users)
• By signup source

Benefits of Segmentation:

• Higher open rates
• Better click-through rates
• Lower unsubscribe rates
• More relevant content

5. Personalize Your Emails

People love to feel like you're talking directly to them.

How to Personalize:

• Use their name: “Hi Ali,” instead of “Hi there.”
• Mention their location or interests.
• Recommend products based on their purchase history.
• Customize subject lines: “Ali, your 20% off deal is here!”

Personalized emails improve open rates by 26% and click-through rates by over 40%.

6. Send at the Right Time

Timing plays a huge role in whether your email gets opened or ignored.

Best Times to Send:

• Tuesday, Wednesday, and Thursday are the best days.
• Mornings between 9 AM–11 AM and afternoons between 1 PM–3 PM usually perform well.
• Test what works best for your audience using data.

Avoid:

• Sending late at night or on weekends (unless your audience is global or night-active).

7. Make Your Email Mobile-Friendly

More than 60% of emails are opened on mobile devices, so your design must look great on phones and tablets.

Mobile-Friendly Tips:

• Use single-column layouts.
• Keep subject lines short.
• Use large, clickable buttons.
• Keep images optimized and lightweight.
• Use readable fonts and sizes.

8. Create Engaging Email Content

Once the email is opened, your content must grab the reader’s attention and lead them to take action.

Content Tips:

• Start with a hook: Make the first line count.
• Keep it short: No one likes reading long emails.
• Use bullet points: Make content easy to scan.
• Add a clear CTA (Call-to-Action): Like “Shop Now,” “Learn More,” or “Sign Up.”

Bonus Tip:

Use storytelling. People connect with stories better than plain sales talk.

9. Use Visuals Wisely

Images make your emails more attractive, but they should support the message—not replace it.

Best Practices:

• Use high-quality images.
• Avoid image-heavy emails (some users block images).
• Always add alt text for each image.
• Use branded visuals to keep your identity consistent.

10. Optimize Your CTA (Call-to-Action)

Your CTA is what you want the reader to click on.

Best Practices:

• Use action words: “Download the Guide,” “Get Your Discount.”
• Make the button stand out with color and size.
• Place the CTA above the fold (visible without scrolling).
• Use only one primary CTA per email to avoid confusion.

11. Clean and Update Your Email List Regularly

Sending emails to people who never open them affects your deliverability.

What You Can Do:

• Remove inactive subscribers.
• Send re-engagement emails.
• Make it easy to unsubscribe.
• Use double opt-in for signups (to ensure valid emails).

A clean list means better open rates and fewer spam complaints.

12. Avoid Spam Triggers

If your email lands in the spam folder, it doesn’t matter how good it is.

Spam Triggers to Avoid:

• Too many exclamation marks (!!!)
• ALL CAPS SUBJECT LINES
• Misleading subject lines
• Too many links or attachments
• Using words like “free,” “cash,” or “guaranteed”

Also, make sure your email includes:

• Your physical business address
• A working unsubscribe link

13. A/B Test Everything

Testing helps you understand what works best for your audience.

Things to A/B Test:

• Subject lines
• Send times
• CTA placement
• Email design
• Personalization tactics

Use tools like Mailchimp, Constant Contact, or ConvertKit to run A/B tests easily.

14. Use Automation to Stay Consistent

Automation helps you send the right message at the right time—without doing it manually.

Common Automated Emails:

• Welcome emails
• Abandoned cart emails
• Post-purchase follow-ups
• Birthday or anniversary emails
• Re-engagement emails

Automated emails usually have much higher open and click rates because they’re timely and relevant.

15. Track Your Results

Always keep an eye on your numbers. You can't improve what you don’t measure.

Key Metrics:

• Open rate: % of people who opened the email
• Click-through rate (CTR): % of people who clicked on a link
• Conversion rate: % who completed your desired action (like a purchase)
• Bounce rate: % of emails that couldn’t be delivered
• Unsubscribe rate: % of people who opted out

Analyze your campaigns and use insights to improve the next one.

16. Build a Strong Email List (Ethically)

Buying email lists is a big no. You want subscribers who want to hear from you.

How to Build Organically:

• Offer lead magnets (free ebook, discount, or checklist).
• Add signup forms on your website, blog, and social media.
• Run contests or giveaways.
• Use popups and exit-intent offers (but don’t overdo it).

17. Focus on Deliverability

Even the best emails won’t help if they never reach inboxes.

How to Improve Deliverability:

• Use a reliable email marketing platform (like Mailchimp, Klaviyo, ConvertKit).
• Authenticate your domain (SPF, DKIM, DMARC).
• Don’t email people who never engage.
• Avoid spammy design and language.

18. Respect Privacy & Be Transparent

People value their privacy more than ever in 2025.

What to Do:

• Be clear about how you’ll use their email.
• Make unsubscribing simple.
• Follow GDPR and other email laws.
• Don’t trick people into signing up.

Being honest builds trust—and trust leads to clicks and conversions.

19. Try Interactive Emails

Interactive emails increase engagement by letting users interact without leaving the email.

Features to Try:

• Polls
• Image sliders
• Clickable tabs
• Quizzes
• Countdown timers

These fun elements can increase click rates dramatically.

20. Keep Improving with Feedback

Ask your subscribers what they want.

• Include simple surveys.
• Ask: “How are we doing?” or “What do you want to see more of?”
• Use their feedback to improve future emails.

Your audience will feel heard, and your emails will perform better.
