What's the Best CTA Button Color for Emails?

Originally published on December 21, 2020. Last updated September 10, 2021.Your email’s call to action is the driving force behind your entire campaign. You want readers to take a step forward in their buyer journey— whether you’re asking them to register for an event, make a purchase or read more of your content.Color is one of the most significant elements in making your CTA button noticeable. But which color converts best? Let’s take a closer look at how brands choose the best button colors for their emails and landing pages.

Your email's call to action is the driving force behind your entire campaign.

What is a call to action?

A call to action or CTA is a specific direction for your reader. Readers skim emails and landing pages, so having an obvious place to click gets them to the next step of their journey faster. CTA buttons are powerful marketing tools. In fact, Healthtech company Carelogger found that just changing their CTA button color increased conversions by 34%.

How color affects choices and feelings

Color impacts how we interpret information. When you’re deciding on a color scheme for your email or landing page, it’s important to consider the connotations of that color.While color interpretation is highly dependent upon personal experiences, certain generalizations can be made about the psychology of color. The Color Emotion Guide from the Logo Company is often cited as a general guide:

People also tend to judge a color based on how appropriate they feel it is for a particular brand. In other words, your customers gauge whether a color fits your brand personality. This means there’s no single “right” color to choose. It’s a matter of what color evokes the energy and personality of your brand.

Best practices for your call to action colors

In order to convert, your call to action buttons needs to stand out from the rest of your design. While there is no perfect color that will lead to higher conversion rates, running A/B tests on different colors is an easy way to optimize your designs. Here are a few approaches to try out:

Use Your Brand Color

Brands often choose CTA button colors that match their logo color to establish design cohesion in email. When a color repeats itself throughout an email, especially at the top and bottom, it gives the whole message a balanced and unified appearance. This is an easy way to reinforce and boost brand awareness.Here’s what a matching scheme looks like in action with HelloFresh. Check out the lime-colored logo and coordinating CTA button.Subject line: Get $90 off! Avoid the crowds, get dinner delivered.

Keep your CTA colors consistent

Subscribers will associate specific colors with actionable items. For instance, hyperlinks are often blue, which let’s readers know they can expect a clickable link in emails when they see a word or phrase in blue. This will go for your CTA color choice as well. Once you assign a color to your call to action buttons, subscribers will quickly learn to recognize that color for your CTAs in all your emails. Don’t confuse your readers by having too many colors for your CTAs. Assign one color for your primary CTA and one color for your secondary CTAs. This consistency will keep subscribers on your same page, always guiding them towards your intentional action items.

Prioritize your main CTA

Focus on choosing the best color for your primary CTA and then begin to think about placement and text hierarchy. Your primary CTA color and placement will purposefully guide your subscribers through your emails. Allison Valenzuela, BEE Freelance Graphic Designer, explains:“With color, you can help guide an audience's eye and how they take in information. Play with color after nailing down the hierarchy of your content and see what makes the most sense for the impression that you want to leave with your audience.”Consider how to keep your primary CTA top of mind when thinking about where to place it in your email. Make its size larger than the rest of your text in a bold shade of color.

Make your CTA pop

An eye-catching call to action will lead to higher conversion rates which means using a button color that blends in with the rest of your email content isn’t your best move when trying to attract subscribers.Allison explains that you should, “Look for a color pairing that allows the button to have a high contrast to the background. An example of high contrast would be a red or an indigo button on a white background.”It’s also important to consider the “isolation effect,” which is basically the idea that something looks more or less attractive depending on what it’s surrounded by. When it comes to color, some research has shown that people have a preference for one strong, bold color that reigns above the rest of the text.Another way to make sure your CTA stands out is by using different CTA colors while sticking to your brand kit. For instance, Instacart updates its CTA button color from email to email, using one green button and one orange button shown below. Both green and orange are Instacart brand colors, but the company makes colors pop more by switching things up within their brand color palette to match the most appropriate color for each message.

Changing your CTA button color from one email to another is effective when you have a well-established style guide and visual identity. Even when you change color schemes from email to email, your emails still reflect the look of your brand.

Test your CTAs

One color is not always better than another, an effective CTA color will vary based on text-hierarchy, brand style and a variety of other key factors. So be sure to set your call to action colors after you’ve tested them multiple times on your subscribers.Implement subscriber surveys to gain feedback on your CTA color and then run A/B tests until you find what leads to the highest conversion rates. Cycle through this process until you’ve solidified what your bulletproof button color should be.

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.
