Kickbox API: What it Is and How it Works

What is the Kickbox API?

 
The Kickbox email verification API is a straightforward tool that helps you stop invalid, outdated, and disposable emails from sneaking into your email lists.

It works at the point of capture. This means as soon as someone enters an email on your site, the Kickbox API checks it. You get a free API key to start with, so you can test it out without spending a dime. When someone signs up, the API quickly sends a response back.

If there’s an error, like a typo in the domain, or it’s a disposable email, the API flags it as false. This way, you don’t accept any bad emails in your lists. It’s all done over a secure HTTPS connection, so your data stays safe.

The function of this API is to keep your email list healthy, which is very important for any business relying on email communication.

How does the Kickbox API work?

The Kickbox API functions as a tool for maintaining the cleanliness of your email list.

Here’s how it works:

Get your API key

First things first, you need to sign up for a free Kickbox account to obtain your API key. This key is essential as it’s your pass to access the API.

Choose your mode

Decide whether you want to use the Production or Sandbox mode. Sandbox is great for testing as it doesn’t use up your credits. As a result, you get mock results for trial runs.

Make the call

When you’re ready, make an HTTPS request to the Kickbox API. You’ll need to include your API key with each call, either as a query string parameter or in the authorization header.

Set your parameters

In your request, you’ll specify the email address you want to verify. Optionally, you can set a timeout parameter to limit how long the API waits before giving up on a verification attempt.

Receive the response

The API will respond with a JSON object containing several pieces of information about the email address. Those include details such as whether it’s deliverable, if it’s a disposable email, and even if there’s a typo that Kickbox has detected and suggests a correction for.

Interpret the results

The JSON response will include a ‘result’ field that can be ‘deliverable’, ‘undeliverable’, ‘risky’, or ‘unknown’. This comes along with a ‘reason’ field that provides more context for the result.

Take action based on the response

Depending on the email verification results, you can then decide whether to accept, flag, or reject the email address from entering your database.

Monitor your usage

Keep an eye on your API usage through the response headers that include your remaining credit balance and the response time for the request.

Handle errors gracefully

If there are any issues with your request, the API will return standard HTTP error codes to help you identify and fix the problem.

When you follow these steps, you can seamlessly integrate Kickbox’s email verification into your systems. This will make your email list remain pristine and your communications reach their intended targets.

What can you use the Kickbox API for?

You can use the Kickbox API for a few key tasks that are crucial for anyone managing email communications:

Real-time email verification

As soon as someone enters an email address on your website – be it through a sign-up form, checkout page, or newsletter subscription – the API can verify that email address in real time. This helps prevent typos and fake emails from entering your system.

Maintaining email list health

The API can check the emails on your list to see if they are still valid. This is great for cleaning up your list periodically. Thanks to that, you’re not sending emails into the void.

Preventing disposable emails

If you’re worried about users signing up with temporary or disposable email addresses, the Kickbox API can identify and block these. This keeps your list filled with only genuine, long-term contacts.

Batch verification

Do you have a big list of emails to verify? The API can handle that too. You can verify large batches of emails in one go, which is a huge time-saver.

Error and typo correction

The API can often detect when a user has made a typo in their email domain (like ‘gamil.com‘ instead of ‘gmail.com‘) and suggest the correct version. This can improve the user experience by catching errors before they become a problem.

Quality scoring

With the Sendex score that Kickbox provides, you can gauge the quality of the email addresses on your list, helping you to segment and target your communications more effectively.

Integration with your Systems

Because it’s an API, you can integrate Kickbox’s functionality directly into your own apps and workflows. As such, automating the process of email verification within your existing tools and systems becomes a piece of cake.

In essence, the Kickbox API helps to transform your email list into a foundation you can build upon, not a shaky structure that could collapse at any moment.

Kickbox API pricing

 
Kickbox offers a “straightforward pricing” structure* that’s designed to fit the needs of organizations of any size.

Starting off, you can test the waters with 100 email verifications free of charge, which is a nice touch for those dipping their toes into email marketing.

As your needs grow, the prices scale up modestly:

• 500 verifications will cost you just $5,
• a thousand doubles that at $10, and so on,
• up to a million verifications for $4,000.

It’s a clear, no-nonsense approach that scales with your business.

And if you’re wondering about API access, the good news is that it’s included with all Kickbox accounts, which means you can integrate their service into your platform right from the start.

This inclusion keeps your list growing, while Kickbox grows with you. Essentially, it’s like a seamless part of your email verification process.

Plus, they throw in some extras like volume discounts, free credits for unknown verification results, and a suite of deliverability tools to keep your email game strong and compliant with GDPR.

And that’s no matter where you are on your email marketing journey.
