Top Tips for Best Call to Action Button Design

Your call to action is probably the whole reason you send marketing emails: You want your readers to actually do something. Whether signing up for an event, downloading an ebook or purchasing a product, the action you have in mind is probably the driving force behind your whole email campaign. So it's critical that your CTA button really brings it home. Messing up your CTA is like putting a mouth-watering steak in front of readers but failing to give them a fork.How can you optimize your call to action button design and boost your conversions? Let's walk through some call to action examples so you can create your own stellar CTA.

Messing up your CTA is like putting a mouth-watering steak in front of readers but failing to give them a fork. So it's critical that your CTA button really brings it home.

Choose a call to action button or link

Both links and buttons have benefits when it comes to CTAs. Links are better used to take readers somewhere — like your website, an article you've referenced or a customer support center. Compared to buttons, links are often less important, urgent and specific.Call to action buttons get your reader to act. Buttons stand out — they take up significant space in an email, helping them get attention. They stand alone as their own component of an email. Even if readers just skim or skip your body copy, they'll still notice that big, bright, shiny button. Buttons are used for the primary action you want readers to take.If your email is well-focused with a key objective or purpose (like getting webinar signups or increasing product sales), the action that will lead to that result is best presented in a well-designed, standout button.

Craft strong call to action button text

Good call to action button design will showcase the email's value proposition in a way that's clear, specific and concise — so readers understand exactly what they're getting by clicking. Here's a good example from Wilton Icing:

call to action button in email

The button makes it clear what will happen if you click — you'll be able to view a guide. The text on your CTA button shouldn't be too short or too long. Three to four words is a good rule of thumb. Think "Download your free ebook" instead of "Click to register for our special ebook deal today." Here's a good example from Lunya:

email call to action button text

Good CTAs are customized, unique, and they reflect the tone of the brand. "Click here," "Register," "Learn more" and "Sign up" are overused and generic; stay away from those if you can. Instead, use personal pronouns like “my” and “your” to set a friendly tone and make a CTA engaging and approachable. Charity:water, a nonprofit bringing clean drinking water to people in developing countries, uses a unique CTA that reflects their brand voice and mission:

Here are some others to try:

  • Reserve my spot
  • Redeem my coupon now
  • Get my free ticket
  • Pre-order yours
  • Claim your seat
  • Get the full scoop

Now that we’ve covered what your email marketing call to action should say, let’s talk about what it should look like.

Tips for call to action button design

Buttons come in all shapes and sizes — some more effective than others. Here's what you need to keep in mind when designing the perfect CTA button.

Remember to make it bulletproof

CTA buttons in email are generally designed one of two ways: with HTML code or with an image. Your buttons should always be written in HTML. Buttons written in HTML — also known as bulletproof buttons — will render across all inboxes, ensuring that all of your customers can see them. You can either make a standard CTA button bulletproof by adding a few lines of HTML code or check that the email editor that you’re using generates bulletproof buttons (and that those buttons are not simply images).The problem with image buttons is that you have much less control of how the image looks across devices (and if it will show up at all). For subscribers who have images disabled, your button won’t show up at all. And no button means no clicks.Here's the Wilton Icing email we looked at above, but with image-viewing disabled. Their bulletproof button still shows up:

In another email from Lord & Taylor, their "Shop shoes" and "Shop handbag" buttons look great with images on...

...but check out how those same buttons evaporate when we aren't viewing images:

Avoid this kind of situation by making sure your CTA buttons are completely bulletproof.

Pick your call to action button size

How big should your CTA button be? You might be tempted to go big to make it visible — but bigger isn’t always better. Readers shouldn't feel like you’re shoving a demand in their faces. Strike a balance by making your button wide if it’s not too tall, or by making it a little taller if it’s not too wide.Check out how REI’s CTA button appears in this email. It feels balanced, with the width of the image, the width of the text and the width of the button creating an inverted triangle effect.

Alternatively, this one from the Getty Museum is a bit over-the-top. The height of the button is in balance with the header (the word "SHOP" is quite tall), but having two lines of text for the button makes it unwieldy, and with a quick scan, it's hard to tell if the button is a button at all.

Screen Shot 2015-11-18 at 3.29.23 PM

It's also important to remember that readers on mobile devices or tablets should be able to easily tap a button with a fingertip, so best practice is to allow ample white space around your button. Here's an example of effective use of whitespace in a message from Melissa & Doug:

mobile email call to action

Including whitespace makes it easy for people to tap.

Choose the best call to action button color

Color is a key way to make your button stand out. Most brands choose a button color that's on-brand and lines up with the design of the email. Often, the button echoes the header design in color (if not also in width or tone). Here's how Zoe’s Kitchen uses the same bright orange color of its logo for an email call to action button:

Other brands rely on a button's border for definition, like this example from Partake Cookies:

email call to action button example

Keep things simple with your color gradients. The best choice is often an on-brand background color or border that helps your CTA button stand out in a good way.

Decide on a shape

From a design perspective, rectangular elements generally connote a sense of traditionalism, practicality and balance. Circular elements can be perceived as soft and calming. Like color, the shape of your button should align with your brand style as well as the design of your email. An email with square and rectangular images or design elements would probably do better with a button that mirrors that style, like this example from The North Face:

email call to action example

And here's how Quip, a toothbrush company, softens the edges of its button to match the circles pictured in the product photo above:

email marketing call to action

These are a few call to action button best practices that can help your button be as effective as possible.

Consider your call to action button placement

Many of the emails in this post follow the best practice of communicating a clear, single message that leads to a clear, single call to action. Research has shown that placing a CTA button below the fold actually increases clicks by 304%! The important thing is to let readers know what they’re signing up for first — with great copy and visuals — and then invite them to act.We’re also seeing a lot of emails in our inbox with multiple CTA buttons. Many of these emails, like the example from Lucky Brand below, have their main CTA halfway through the email. Then they list several specific products, adding a separate CTA button for each one.

If you’re sending browse or cart abandonment emails, it can be helpful to give customers a specific CTA button for each product they’ve previously considered.

Your call to action button design checklist 

There are as many button styles out there as there are emails. Take note of how the brands you admire are designing their CTAs and test the effectiveness of different button styles to see what works best with your audience. Remember these rules of thumb for your call to action button design:

  • Write action-oriented, compelling and unique copy for your button
  • Keep the copy direct and clear, making sure readers know exactly why they're clicking
  • Make sure your button is bulletproof (written in HTML so it always renders)
  • Check that your button "pops" (stands out visually)
  • Consider your visual brand identity and the style of your email when choosing a button's color and shape
  • Place your button in an easy-to-find spot that fits organically in the story of your email (probably below the fold)

Now, let's be honest—you’ve likely heard about all of these rotating for the last few years. While email marketing has come a long way and is changing faster than ever, there’s only so much you can do within 600x1,500 pixels. However, there are no limits to where your creativity can take you. 

Let’s get into it.  

#1. Unique, tailored experiences 

Damian Grabarczyk, the co-founder and growth marketer of PetLab Co., says, “We faced the challenge of connecting meaningfully with an audience that expects more than one-size-fits-all communication.” 

When we speak about crafting tailored emails we mean going beyond the recipient's first name in the subject line. We’re talking about optimizing your entire email strategy to design multi-stage touchpoints to nurture leads across the customer lifecycle. As well as, leveraging data to send hyper-personalized, relevant, and engaging emails that feel less like a broadcast message and more like a conversation. 

Many are using AI machine learning algorithms and AI automation to analyze customer interactions, past purchases, browsing habits, website visits, and even social media behavior to curate engaging email content that resonates deeply with the real-time needs of recipients.

For PetLab Co this looked like including content such as an individual’s pet health history or product usage timelines. Damian Grabarzyk expands, “This approach transformed the conversion rate and strengthened customer loyalty. As we look ahead, I see brands in 2025 moving beyond generic personalization to adopt strategies that make customers feel truly understood and valued.”

On the other hand, many are leaning into user-generated content (UGC) for crafting tailored experiences. Customers today are more likely to trust the opinions of peers over branded messages. UGC like customer reviews, testimonials, videos, and photos are the best form of social proof depicting real people using and benefitting from your products or services. 

We see the benefits of using both AI and UGC to get the most out of your email conversions ;). 

#2. AI tools as an addition, not a substitution

Experts at NordPass state, "AI-powered content generation tools are not here to replace email copywriters and marketers. These tools make us more efficient. The smarter the tool is, the better equipped we are to create high-performing email content that drives results." 

AI tools can support us by significantly enhancing the speed, precision, and effectiveness of your emails. For instance while traditionally A/B testing has required a lot of time to analyze small variations with AI you quickly implement and test multiple email elements and make adjustments based on real-time engagement data. There are AI algorithms that can even predict which variations are most likely to resonate with different audience segments, leading to more accurate targeting and faster optimization.

In short, AI tools are revolutionizing the way we craft and optimize our email’s deliverability. There are many different types of AI solutions so we suggest finding the right one for your needs. 

#3. Even more transparency around data

With AI continuing to rise, folks are more and more concerned about where their data is going. That’s where zero-party data collection becomes a key strategy in email marketing, allowing you to gather data directly from customers rather than relying on third-party sources. 

Zero-party data includes information that consumers willingly share, such as preferences, interests, and purchase intentions. This data is often collected through surveys, preference centers, quizzes, or interactive content and is highly valuable because it is shared explicitly, ensuring accuracy and deeper personalization without privacy concerns associated with third-party tracking.

As privacy regulations tighten, zero-party data will empower you to deliver hyper-personalized email experiences while respecting user privacy. This approach will help you build trust, as customers feel more in control of their data, and you gain insights that lead to more relevant and engaging email content.

#4. The death of static emails

With attention span getting shorter day after day, digest-format emails are expected to rise in popularity in 2025. Presenting email content in an easy-to-scan, organized, and minimalistic layout will surely help deliver the most relevant information in a fraction of the time. 

Additionally, interactive emails will allow recipients to directly engage within the email without having to visit a landing page or website. Interactive elements like product carousels, polls, and quizzes create a dynamic experience that keeps subscribers engaged, especially in visually driven industries like fashion brands

So what now? 

You’ve heard these strategies before, but now it’s time to actually put them into action. The brands that win at email marketing in 2025 won’t just be sending emails—they’ll be creating experiences. Whether it’s hyper-personalized content, AI-driven efficiency, zero-party data collection, or interactive emails that break the mold, the key is to stay ahead of the curve.

So, what’s the first strategy you’ll finally implement? Your inbox (and your audience) are waiting.

What do customers think about your brand’s products? The best way to find out is to ask them directly, which you can do via strategic email campaigns.

Email makes gathering authentic product reviews quick and easy. By collecting sincere feedback, you can build trust, increase sales, boost loyalty, and innovate product improvements. 

That said, requesting reviews via email requires precise timing, personalized messaging, and lots of engagement optimizations. But don’t worry—we’ll walk you through some key steps to create email campaigns that deliver the valuable feedback you need.

Why product reviews matter

Product reviews do more than confirm that you're meeting customers’ needs. Sincere feedback drives loyalty and sales, offers valuable customer insights, and helps you develop a strategic product development roadmap.

  • Fosters customer loyalty: Requesting and listening to feedback makes your customers feel valued and heard. It demonstrates that you prioritize customer satisfaction, which helps you build stronger, long-term relationships. Review requests also act as re-engagement emails by starting new conversations with customers.
  • Increases sales: Social proof drives sales. According to a recent survey by Power Reviews, 90% of potential customers use online reviews to make purchasing decisions. In fact, reviews have more influence over purchasing decisions than product prices. Turning product reviews into customer testimonials and encouraging reviews on third-party sites can significantly boost sales.

  • Builds Customer 360 insights: Customer feedback delivers insights into customer needs and sentiments, enriching Customer 360. Exactly what is Customer 360? It’s a unified, 360-degree view of customer data. It empowers you to tailor products and customer experiences to meet individual needs and preferences. 
  • Drives product improvements: Sincere customer feedback reveals what target customers like/dislike about your products. It provides key insight into their value, functionality, and usability, unlocking large-scale development opportunities.

How to create an email campaign to collect product reviews

Want to unlock the power of product reviews? Let’s explore how to create email campaigns that encourage customers to share their feedback.

Segment your audience

Like promotional emails, product review requests shouldn’t be sent to every subscriber.

If subscribers haven’t had the chance to try your product, product review requests will feel irrelevant and may trigger unsubscriptions. So, only send review email requests to customers recently trying your product.

You can do this by segmenting your email list based on where customers are in the buying cycle. Target loyal customers, recent purchasers, and first-time buyers with tailored email campaigns. This ensures that you’re sending emails to customers most likely to respond with insightful feedback.

Write a compelling email subject line

According to Superoffice, 33% of people open an email based on the subject line.

To get the click-through rates you want, your email subject lines should be personalized, relevant, and engaging. Here are some examples:

  • Did you love [product]? Or hate it? Let us know!
  • We value your opinion — help us improve!
  • We want YOU to help us make our product better!
  • Up for a discount? Share your feedback for 10% off!

Optimize for customer engagement

A successful email marketing strategy relies on customer engagement. Here are some key email elements you need to encourage interactions.

  • An attractive email design: With the right layout, color scheme, typography, and images, you ensure easy readability and promote interaction. Use these engagement-boosting email design best practices to help you create a design that boosts conversion rates.
  • Gratitude and value: Thank customers for reading the email and explaining why their feedback is so important. Also, consider including a personalized Gmail email signature with your content details to build trust and encourage customers to engage with your review request. 
  • Personalized, relevant content: Personalized email content motivates engagement. Use customer data platform (CDP) data to tailor messages to individual customers. What is a CDP? It’s a centralized platform that collects and unifies customer information, building comprehensive customer profiles. 
  • Incentives: Offering a small discount can motivate customers to leave reviews, especially first-time buyers. That said, incentives can (sometimes) generate insincere reviews, so stress the importance of honesty. 
  • A strong call-to-action (CTA): Your CTA should direct readers straight to the reviews submission page. Use clear CTAs with bold buttons and typography to make it stand out.
  • Mobile responsiveness: If your emails are slow to load or don’t display correctly on mobile devices, your bounce rate will spike. Leverage solutions that offer advanced mobile optimization features — such as Beefree— to create responsive emails every single time.

Ask specific, concise questions

Complex, drawn-out questions that are too open-ended can disengage customers. So, get straight to the point with concise, direct questions. Here are some examples:

  • What did you think of [specific product feature]?
  • How often do you use our product?
  • What are your favorite/least favorite features?
  • How likely are you to recommend this product?
  • What could we do to improve our product?

Use a mixture of closed and open-ended questions to increase your chances of receiving meaningful responses.

Make it easy to respond

The easier it is for customers to leave a review, the more responses you’ll receive. So, make the process as seamless and convenient as possible. One way to do this is with survey emails.

Email surveys have high response rates. They can be completed within the email with minimal effort, which is a big plus for busy customers. And, they can generate a wealth of quantitative data and metrics that are quick to analyze, leading to faster improvements. BeeFree has an extensive collection of email survey templates to suit every need.

For longer review requests, include a CTA that directly links to the review submission page. Review forms should use simple, clear language, be optimized for mobile, and have a progress bar. 

You could even provide your telephone contact details to allow customers to leave a review via telephone. It’s the preferred communication method for 55% of Baby Boomers according to Hubspot, so it’s worth considering. 

Leverage small business telephone services from Vonage to access call center capabilities like virtual receptionists and CRM integrations, streamlining processes.

Also consider directing customers to leave reviews on popular review sites, such as Google and Amazon.

Optimize email timings

If you send product review requests too early, there’s a chance your customers won’t have tried your product yet. But if you send them too late, your customer might have forgotten their experience. 

So, when’s the best time to request reviews? 

Aim to send review requests within 7-14 days post-purchase. This gives customers a chance to try the product a few times, leading to more sincere, meaningful reviews. Plan for seasonal surges such as Black Friday and incorporate them into your schedules.

Key takeaways

Do email campaigns work for gathering valuable product reviews that drive improvements, boost trust, and increase sales and loyalty? 

Absolutely — but they need to be strategic.

To generate sincere reviews and valuable data, ensure your marketing emails are personalized, engaging, and optimized for convenience. And, use email list segmentation and marketing automation to ensure they’re sent to the right customers at the right time.
