How to design bulletproof CTA buttons in email

Earlier this week, we gotinspired by the email design of a recent webinar invitation email from Skillcrush, a coding academy that focuses on teaching women how to code. Their webinar invitation email had all the relevant information—event time, cost, key details, and a way to register—but they didn't get boxed in by the standard, bland email template we so often see... and that we start to tune out. Instead, they created an engaging, personality-packed webinar invitation email. There's plenty to learn from! Check out our email design tips on How Skillcrush Built a Unique Webinar Invitation Email.In today's workshop, we're going to focus on a key design element of the Skillcrush email: the bulletproof call-to-action (CTA) button. But first, what does bulletproof mean? It's a term used by email professionals for a CTA button, written in HTML, that renders across all inboxes and, because it's HTML code and not an image, the CTA button will always be shown, no matter what.Now that we know what a bulletproof button is, the next step is to figure out: how do we design one? And this is where it can be a little bit tricky for some. You can either turn 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). We'll look at how to design a bulletproof button with the use of the BEE email editor.

How a bulletproof CTA button should look

Let's start with a look at the bulletproof button from the Skillcrush email. For reference, here's the full email:

And here's a close-up of their unique call-to-action button:

It's a refreshing change of pace fromthe typical "webinar blue" button weoften see, like this one:

Notice how Skillcrush uses smart design tactics for its CTA button, which in turn reflectits modern, feminine, and personable brand:

  • The button is on-brand pink with bright white text
  • It's the full width of the email and doesn't have a bulky outline (like the black one around the "Register Now" button), evoking a light, modern feel
  • "Claim your spot," with the use of a personal pronoun "your," has an approachable, friendly tone while still directing readers to act

But perhapsthe most important design feature ofthe CTA button is that it’sbulletproof, meaningthe button is written in HTML so that it fully renders on all inboxes. We can see how the button is shown even with images turned off on iPhone:

Let's now get much more hands-on and see how to design a bulletproof button ourselves and recreate the Skillcrush CTA button. We'll be using the BEE email editor, which generates bulletproof CTA buttons.

Be sure to follow along and open the BEE email editor in a new browser tab. The BEE email editor is free, online, and requires no registration. So, do give it a try!

Video Overview: How to design a bulletproof CTA button

As a quick overview, here's our video tutorial on how to design the bulletproof CTA button from the Skillcrush email in the BEE email editor:

A step-by-step guide in the BEE editor

Let's walk through how to easily create a stellar CTA button in the BEE editor, where we have full customization of width, border radius, border color, padding, and color and text styling.

screenshot-beefree.io 2015-10-14 12-57-07

To get us started, we took a couple minutes to recreate the top portion of Skillcrush's email,populating abasic one-column templatewith the header image and intro content. (For a step-by-step guide on how to set up a modular single-column email, check out this workshop post).Now, let's create our button!Over in the Structure menu to the right, we'll grab a button content block and simply drag it into the body of our email.

Screen Shot 2015-10-14 at 1.07.24 PM

Notice that the default button is blue, rectangular, and centered on the page:

Screen Shot 2015-10-14 at 1.10.46 PM

But there's a lot we can do to customize it! To match Skillcrush's button, we'll need to:

  • Change the background color
  • Update and style the text
  • Increase the width and adjust the padding
  • Insert a link

In the body of our email, we'll click on the button structure to activate it, then start making our adjustments in the Content menu on the right.

Button color

First, we'll set the button color to pink(#F16059 in hexidecimal format) to match Skillcrush.

Screen Shot 2015-10-14 at 1.24.23 PM

Then, we'll update the text. As we type, the button automatically widens to accommodate our content:

Screen Shot 2015-10-14 at 1.25.58 PM

We can keep our default font color (white #ffffff), font family (Arial), and font size (16px), but we'll make our messagebold (and be sure to type in all caps).

Full button width

Makingthe button stretch to the full width of the email body is easy. Back in the Content Properties menu, we'll adjustthe width slider to the right, up to 100%. From a design perspective, the full width makes sense: it mirrors the Skillcrush header at the top of the email, providing an aesthetically pleasing balance, and it also givesmobile readersmore space to click.

Finishing touches

Under Content Padding, we'll make sure we have a padding of 5 px top and bottom.Let's also remember to insert a link to the button: in the same Content Properties menu we've been working from, we'll scroll to the Action section and paste in our link.

ScreenShot1414

Now, we have a fully functional bulletproof CTA button, identical to the Skillcrush email! Wasn't that easy?

Screen Shot 2015-10-14 at 2.24.53 PM

If you would like to further customize the CTA button, here are a few additional button design settings in the BEE editor:

Border radius

You can adjust the Border Radius to change your button's shape. From a design perspective, rectangular elements generally connote a senseof traditionalism, practicality, and balance, while circular elements can be perceived as softer and calming.

ScreenShot1412

Here's a rounded version of our CTA button after adjusting theradius to25 px:

Screen Shot 2015-10-14 at 2.35.15 PM

Button padding

We can also make the button taller (or shorter): make sure the "More options" button is turned on in the Content Padding section, and bump up thetop and bottom padding.

ScreenShot1413

Here's our button with an upper and lower padding of 20 px.

Screen Shot 2015-10-14 at 2.43.23 PM

Borders

Another adjustment we can make is the color and width of the button's border, found under Content Properties in the BEE editor. Notice how we have granular control on borders (to learn more watch a quick video tutorial on borders).

ScreenShot1415

The traditional "Register Now" button we looked at earlier had a thin black line around it. In the Border settings in the BEE editor, we can play with different colors and thicknesses.A thin, light border adds a bit of depth:

Screen Shot 2015-10-14 at 2.50.05 PM

And slightly thicker, darker border is more prominent but has a similar effect:

Screen Shot 2015-10-14 at 2.51.14 PM

Switching to a totally different color generally detracts from the light, modern feel of the button:

Screen Shot 2015-10-14 at 2.53.53 PM

But a border can also be useful in maintaininga light, airy, and modern look if weomit a background color, like this:

Screen Shot 2015-10-14 at 2.56.01 PM

As you can see, we could spend probably all day customizing a CTA button in the BEE editor!

Our CTA button design takeaways

As you're designing your own emails and customizing your CTA button, hereare the key thingstokeep in mind:

  • Buttons should be on-brand, too. Skillcrush does a great job of demonstrating how a well-designed button can go a long way in reflecting your brand so you can connect with your audience. Play with colors and styles to achieve a look that matches both your brand identity and your email's aesthetic. The button should attract attention (it should be obvious that it's a button) but not stick out like a sore thumb.
  • Balance the size of your button. Bigger isn't always better. Don't make your readers 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. Remember, readers on mobile devices or tablets should be able to easily click with a fingertip, so allow ample white space around your button.
  • Don't forget content! "Register," "Learn more," "Sign up," and similar CTAs are overused. Think about how you can customize your message in a way that reflects the tone of your brand. Be sure to use a clear, direct action verb—and be concise. Try using personal pronouns like "my" and "your" that make your message friendly and engaging. You could try: "Reserve my spot now" or "Get my free ticket."
  • Placement is key. Research has shown that placing a CTA button below the fold actually increases clicks by 304%! Let readers know what they're signing up for first—with great copy and visuals—then invite them to act. Skillcrush does exactly this by placing their CTA button last.
  • Be bulletproof. Above all else, it's critical that your button looks great and works as it should, no matter the device or email inbox. Always use HTML instead of an image. We've seen that in the BEE editor, all buttons are bulletproof, so you'll never need to worry about how they'll render!

This flexibility is especially beneficial for maintaining a low code architecture in website design.

2. Personalize

Consistency is key to building trust, and when your emails have a cohesive look, it helps recipients recognize your brand.

8 Common Email Spam Triggers That Can Damage Your Sender Reputation

Whether you’re employing a lifecycle email marketing strategy or simply confirming an order, we’ve outlined the basics of how spam prevention works, why it matters, and how to avoid running afoul of some commonly used triggers.

In 2024, roughly 361.6 billion emails were sent per day. Whether you're using email for business or to keep in contact with your long distance cousin (do people still do this?), it’s easy to picture just how clogged someone's email can get. That's where modern day Email Service Providers (ESPs) come to save the day with trigger-based spam filtration tools.

For user these spam filters help ensure a smooth email experience, free of spammy and fishy emails. However, as email marketers, these filters lead us to be overly cautious out of fear that our emails are not accidentally filtered out.

Whether you’re employing a lifecycle email marketing strategy or simply confirming an order, we’ve outlined the basics of how spam prevention works, why it matters, and how to avoid running afoul of some commonly used triggers.

Why you need to avoid email spam triggers

Whether you’re an ESG reporting software or a travel company email spam triggers can email marketing performance and in turn hurt your business. For one, there’s the obvious reason that if your emails get sent to the spam folder, they probably won’t be seen. That's time and effort wasted.

Beyond that, being sent to the spam folder too many times delegitimizes your email marketing, which damages what’s known as your sender reputation. When just starting out, this reputation is effectively neutral. But if it gets too low, it could damage your marketing performance and even result in being blocklisted.

How email spam filtering works

As mentioned above, spam filters are implemented as a form of quality assurance and protection for end-users. Here's how ESPs determine content to be spam:

  • Sender reputation analysis: ESPs check sender reputation based on authentication, user complaints, bounce rates and sending patterns. They’ll also check the reputations of your IP address and web domain.

  • Content analysis: Content filtering uses triggers like keywords, formatting and error detection to distinguish spam from legitimate email marketing.

  • Blacklists: Along with sender reputation metrics, ESPs also cross-reference email senders against any of several blacklist databases. Being on even one of these means you’ll struggle to climb out of the spam folder at all.

8 common email spam triggers and how to avoid them

Now let's get to the good stuff. Prevention is generally the best strategy when it comes to avoiding email spam triggers. Here are seven factors commonly used by ESPs to filter spam emails, and the simplest solutions for dealing with them.

1. Lack of authentication

Missing authentication is one of the first red flags an ESP will pick up on. Authentication shows you’ve taken certain steps to establish legitimacy. It’s also used to prevent fraudsters from impersonating your brand online. There are three commonly used forms of email authentication:

  • Sender Policy Framework (SPF): This means publishing a list of mail servers and IPs with permission to send messages using your domain. This is one reason it’s important to conduct email marketing through a branded business email, rather than a personal account.

  • Domain Keys Identified Mail (DKIM): A cryptographic signature which shows a message’s original content has not been altered during sending. Think of it like the tamper-proof seal on a bottle of milk.

  • Domain-based Message Authentication, Reporting and Conformance (DMARC): A way for you to establish how you want receiving platforms to handle authentication failures related to your domain.

2. Shady linking practices

Link placement and presentation play an important role in email marketing. Aside from engaging recipients and securing click-throughs, using links appropriately helps avoid your emails looking like spam.

Questionable linking practices include:

  • Links to domains with poor reputations
  • Excessive numbers of in-email links
  • Compressed, modified or obscured links, particularly when generic link shorteners are used

Only link to your own authenticated domain. Also, use an unlimited bandwidth VPS to help ensure your website access speed is always stable and fast. This will give visitors the assurance that your site is legitimate.

Don’t forget to make the purpose of any in-email link absolutely clear.  

3. Content

Although the reason for an email landing in a spam folder is often related to authentication, reputation, or poor formatting, content can at times be the culprit. Here are elements that you should look at if you suspect that your content is why your emails are not reaching their recipients:

  • Typos
  • Irrelevant content that doesn’t foster positive engagement
  • Poorly translated text
  • Partner content with poor reputation
  • Possibly offensive content
  • URLs or images with poor reputation

Another thing to note is language detection filters. Various words, phrases and tone choices have strong associations with scam emails. This includes certain buzzwords, vague or exaggerated claims, or excessive sales jargon. However, this is only really an issue when you already have a bad reputation.

Nevertheless, let’s say you’re beginning to build your reputation back up and are conducting Black Friday email marketing. While it’s important to use engaging language and strong CTAs, you should avoid terms like:

  • Limited time only
  • 100% free
  • Make money from home
  • Avoid bankruptcy
  • You have won

4. Bounce rates

A ‘bounce’ is when an email doesn’t arrive in the recipient’s inbox. This could be due to it being sent to a fake email address, an out-of-date email that is no longer in use, a full inbox, etc.

When a sender frequently experiences high bounce rates for their emails, this damages their reputation with ESPs.

But how do you improve bounce rates and, therefore, your reputation? The best way is to have good segmentation practices to ensure the right content goes out to the right people. You should also keep your list clean by regularly evaluating it and removing hard-bounce email addresses as well as inactive subscribers.

Moreover, ensure you send relevant messages that your audience actually wants to receive. Of course, always be mindful of the rest of the triggers on this list to make sure you’re protecting your sender reputation.

5. Misleading email subjects

Even if you’re not trying to do anything malicious, misleading subject lines can trigger email spam filters. For example, an email might claim to promote educational B2B content about internal audit controls. Then, instead, link the user to a landing page to sell them a product.

Always set clear topic sentences as email subject lines. Try to summarize the content and intent of the email. If you’re sending a welcome email for customer retention or promoting, say, a product or sale, make it obvious before the recipient clicks on it.

6. Poorly written and formatted emails

Poor formatting and low-quality writing are other important email spam triggers. Common writing triggers include:

  • Overly vague language lacking personal detail
  • Typos and spelling errors
  • Being too brief

A marketing email can trigger spam filters if it lacks formatting of any kind, or if there are inconsistencies. It’s also suspicious when marketing emails lack branded color schemes, imagery or the correct logo design.
Avoiding these email triggers is simply a matter of emphasizing professional communication standards in email marketing.

7. Poor engagement

Low engagement manifests itself through a lack of interaction with your emails from the recipients—low open rates, click-through rates, and conversion rates, as well as low subscriber count are all indications. 

Consistently low engagement will likely result in your emails being filtered into spam. To combat this, you should strive to deliver good and captivating content tailored to your audience. More specifically, you can:

  • Use segmentation to personalize your emails and craft the most compelling content for each segment.
  • Put together attractive subject lines
  • Make use of solid and clear CTAs

8. Getting blacklisted

Improving your sender reputation, also means you don’t run the risk of being blacklisted. Blacklists are a useful prevention tool, but if you end up on one of these lists, your email marketing is more or less guaranteed to end up in spam folders.

Aim for prevention with email security and compliance training, and don’t send unsolicited marketing emails. You can also use a blacklist checking tool to make sure your sender emails haven’t been compromised.

Maintaining your sender reputation is essential

Email spam triggers aren’t all bad, they ensure that your well crafted messages aren’t drowned out and that users are able to easily see the emails they’re interested in. 

To reap these benefits, you need to keep an eye on these triggers and protect your sender reputation. Don’t worry, though. It’s easy to deliver marketing copy that avoids email spam triggers once you know what they’re looking for.
