How to Set Up a Banner Email Captcha for Digital Marketing

Email marketing is one of the most effective ways of getting new customers and generating leads. But just like any other marketing channel, email marketing is not easy to automate and scale. That’s where a Captcha solution comes in.

If you’re looking to set up a Captcha solution for your email marketing program, here’s what you need to know.

Why Set Up a Captcha For Your Email Marketing?

You might be wondering why you need a Captcha solution for your email marketing. Well, first off, spam is an issue. The U.S. government considered spam to be “unsolicited commercial email” (ICEM), and as a result, introduced the CAN-SPAM Act in 2003. (

According to the CAN-SPAM Act, a business that sends out more than 10,000 pieces of spam in a single year faces heavy penalties.

In addition to the heavy penalties that come with violating the CAN-SPAM Act, sending spam is also a major turnoff for potential customers. People hate to be spammed, and it puts a major damper on a business’ credibility to be seen as an open mail-order pharmacy or a telemarketer. For these reasons, it’s essential to verify that a subscriber is human before sending them email.

Another big problem for email marketers is that people are just becoming tired of reading endless emails. According to HubSpot Blogs research, people unsubscribe from email lists that send useless content regularly. That’s why it’s essential to provide value in your email messages. If you do, you’ll find that people are more likely to stick around and engage with your content.

How Do I Set Up a Captcha For My Email Marketing?

If you want to set up a Captcha solution for your email marketing, you need to do a few things. First off, you need to decide what type of Captcha you’ll use. There are three major types of CAPTCHAs:

ReCAPTCHA, Solver, and Typeahead. Each one offers some unique features, so you want to ensure that you choose the best one for your needs.

Now, you might be wondering what all the fuzz is regarding the solver Captcha. In fact, many people think that the solver Captcha is unbreakable and essentially ‘impractical’. While it’s true that solving complicated captchas is a very difficult task, not all captchas can be easily solved. There are also ‘bots’ that can automatically solve complicated Captchas for spammers.

The reCAPTCHA and Typeahead Captcha are the most popular ones, and for good reason. They’re both easy to implement, and because they’re easy to use, they don’t require lots of training for your staff.

Which One Should I Use?

Well, that depends on your needs. If you want to completely cut out the spam, then go with the reCAPTCHA. If your goal is to get as many people as possible to click on a confirmation link in order to verify their identity, then choose the Typeahead Captcha. Last, if you just want to reduce the number of people who unsubscribe from your emails, then opt for the Solver Captcha. Each one has its perks, so ensure that you pick the one that meets your needs best.

Implementing A Captcha Solution For Email Marketing

Once you’ve picked the right type of Captcha, you need to move on to the next step. This is where things get a little tricky. You see, not all Captcha implementations are created equal. Some solutions are much easier to set up than others, and depending on your familiarity with code, this can be a minor or major hassle. Here’s a short list of things you need to check before you move forward:

Server Configuration – Make sure that you’ve deployed your Captcha solution on a web server that’s accessible from anywhere on the internet. This ensures that you can use the solution from anywhere and that you don’t have to worry about accessing the web server from outside of your own network. In addition, you need to make sure that the server is configured to handle emails containing sensitive information. Be sure to consult your email service provider regarding the required settings.

Back-End Configurations – Your CAPTCHA solution needs to integrate with your email marketing platform of choice. This means that it needs to be accessible via a web-based API, as well as through a.NET or PHP SOAP client. Most businesses will have some sort of back-end configuration that needs to be done before you can use the solution.

User Interface – The last thing you want is a user interface that’s unintuitive or poorly designed. When setting up your CAPTCHA, try to choose a theme and design that your users will find easy to navigate. Aesthetics aside, you also need to make sure that the solution is easy to use.

What About Spam Tolerance?

You might be wondering about the spam tolerance settings for your new Captcha solution. After all, you don’t want to block legitimate email messages just to keep spammers at bay. The truth is that there’s no need to be overly concerned with spam tolerance when it comes to Captcha solutions. In fact, according to HubSpot Blogs research, most users have very little to no problem with receiving spam. As long as you’ve implemented a decent privacy policy and you provide value, your users will have no problem being engaged with your content.

How Many Questions Should The Captcha Ask?

Another important question to ask is how many questions should your Captcha ask? Theoretically, the more questions you ask, the better. However, in practice, the answer is a little more complicated. If your users are experiencing any difficulties, they’ll be confused as to why they’re having trouble with the Captcha. So, above a certain point, the more questions you ask, the more likely users are to become frustrated and leave.

If you’re worried about people taking your content for spam, then ask for only one or two questions. Solver Captcha’s two-question demo can be easily seen as a spam trap, so don’t use it if your goal is to increase engagement levels. In addition, if you want to keep people around, give them a decent amount of trouble. More specifically, give them a challenge that’s tied to something valuable. For example, if you’re selling products, ask for their shipping address. You’ll find that people are much more likely to give you their shipping address if you’ve made the process hard. In that case, the more questions you ask, the greater the chance that you’ll obtain a valid shipping address.

What Should The Captcha Ask?

Now that you know how to set up a Captcha solution for your email marketing, you need to figure out what the heck you’ll ask your users to do. Remember, the goal is to verify their identity. For this reason, you’ll want to choose a challenge that’s tied to something valuable. In practice, this means that you’ll want to ask for information that can be uniquely identified.

Ask for just enough information to make the process difficult. Also, ensure that the information you’re collecting is of value. Otherwise, there’s no point in running a Captcha. In order to make the Captcha process worthwhile, you’ll want to make sure that the information you’re collecting is relevant to your business.

Where Do I Display The Captcha?

Once you’ve set up your Captcha, you need to decide where you’ll display it. As much as possible, you don’t want to clutter up your webpage with unnecessary design elements. So, if you decide that using the Captcha is important, ensure that you’ve used a clear call-to-action (CTA) button that encourages your users to solve the puzzle. This way, you can easily direct them to the relevant page on your site.
