NeverBounce API: The Email Marketer’s Review

But what if there is another solution?

One that is just as powerful but perhaps a little more flexible, easy to use or, dare we say, better suited to your needs?

This article discusses the NeverBounce API and explores how it helps manage your email verification. If you’re looking for an upgrade, we’ll introduce another API that might better fit your workflow.

Ready to get started?

What is the NeverBounce API?

The NeverBounce API is a service that allows developers to integrate email verification capabilities into their applications.

The API supports both individual email verifications and bulk verification requests. It enables customized integrations for various software solutions and provides callbacks for successful or failed verification responses.

NeverBounce API top features

NeverBounce‘s verification API is packed with features that are designed to keep email lists accurate and up-to-date.

Here’s a rundown of its core capabilities.

1. Real time. It verifies email addresses as users enter them and prevents bad data from entering your lists.
2. Bulk email verification. You can upload and verify large batches of emails in one go.
3. Webhook support. You can get instant updates and receive notifications about the status of each verification.
4. Email address validation. The API checks each email’s format and whether the domain exists. Emails on your list will be well-formed and reach valid domains.
5. Detecting temporary and disposable emails. You can quickly weed out temporary or disposable email addresses that can clutter your list and lead to unreliable metrics.
6. Detailed status codes. The API provides comprehensive status codes (such as valid, invalid, and disposable) and allows for better list management.
7. API key. For added security, you can manage access through multiple unique API keys. This feature helps authenticate requests securely.
8. Analytics and reporting. You can get valuable insights into your email list’s health with built-in analytics and reporting.

What can you do with the API?

The API from NeverBounce offers quite a lot. You can connect NeverBounce account with other tools, build custom workflows, and even embed it into your website.

Let’s get to more details.

Integrating tools and platforms

The NeverBounce API can connect seamlessly with CRMs like Salesforce, marketing platforms like HubSpot, and email marketing tools like Mailchimp. Integrating with such platforms allows you to validate emails before they’re automatically added to your lists.

NeverBounce also lets you create custom integrations, so you can adapt your account to your system’s unique tools or workflows.

• Example: You’re using Mailchimp to handle email marketing. You can set up a process where every email added to Mailchimp goes through NeverBounce verification. As a result, you will prevent invalid emails from reaching your lists.

Note: To securely use NeverBounce’s API, you’ll need an API username (a unique identifier for your application) and a secret key for authentication (it acts as a password that adds a layer of security.) These credentials let only authorized users interact with the API.

Embedding verification on your website

NeverBounce API offers a JavaScript Widget for easy direct embedding on your site.

This widget verifies email addresses in real-time, which is particularly useful for sign-up or contact forms.

The widget’s API (available as window._nb.api in the browser) has a few handy methods, such as getValidatePublic, which verifies an email entered by the user.

• Example code:
  

_nb.api.getValidatePublic('[email protected]',

function(result) {

console.log(result); // Returns a result object with verification data

},

function(err) {

console.log(err); // Returns error message if verification fails

}

);

Note: If you are not a developer, handling the APIs may seem complicated. Using this widget is a better choice for non-technical users.

Building custom workflows with API endpoints

With NeverBounce’s API, you can use various triggers, actions, and searches to create custom workflows. For example, to automate bulk email verification, real-time checking, or specific list verification processes.

Also, the bulk endpoint can run sample checks on lists to estimate bounce rates without incurring costs.

• Example: If you have an extensive list of contacts, you can use the jobs/create endpoint to upload and verify a CSV list. NeverBounce’s API handles this process, from indexing to deduplication, with the ability to check verification status through polling.
• Example code:
  

curl --request POST \

--url https://api.neverbounce.com/v4/jobs/create \

--data key=your_api_key \

--data input_location='remote_url' \

--data filename='YourFile.csv' \

--data input='https://yourdomain.com/YourFile.csv'

Once submitted, this job runs until completion, and you can poll the jobs/status endpoint to check its progress.

Using webhooks for real-time updates

NeverBounce’s webhook support allows for automated result processing. Once verification is completed, you will receive notifications on the status of each verification.

It’s a good way to automate data pipelines, where each change in verification status triggers specific actions in your CRM or email system.

• Example: If an email is verified invalid, the webhook can trigger a workflow to mark the contact inactive in your CRM. Your lists will be constantly updated with verified contacts.

Running free analysis to assess list health

If you’re unsure whether a complete verification is necessary, NeverBounce’s API offers a free analysis feature to assess your list’s overall health.

This option provides an estimated bounce rate and helps you decide if further action is required. To get an estimate, create a job with the run_sample parameter.

• Example code:
  

curl --request POST \

--url https://api.neverbounce.com/v4/jobs/create \

--data key=your_api_key \

--data input_location='remote_url' \

--data filename='YourFile.csv' \

--data input='https://yourdomain.com/YourFile.csv' \

--data run_sample=1

Optimizing email and list verification

Moreover, NeverBounce’s API offers help for optimization, whether it’s verifying individual emails or validating bulk lists. 

You can check single emails as they are entered (e.g., at the point of form submission) or entire lists to clean up existing databases.

When you upload a list through the API, NeverBounce automatically indexes and deduplicates the entries, which helps remove duplicates and spot invalid or risky emails before sending.

You can also use the following request to verify a single email.

• Example code:
  

curl --request POST\

--url https://api.neverbounce.com/v4/single/check?key={api_key}&email={email}

This command allows you to verify a single email using the NeverBounce API by substituting your api_key and the email you want to check.

Note: The standard API from NeverBounce is not suitable for use in client-side scripts (e.g., React, Angular, Vue, jQuery, and other Javascript frameworks), as it would involve revealing sensitive API credentials. Using a Javascript widget is, therefore, a more suitable option.

How much does it cost?

NeverBounce does not provide information on the cost of its API service, but it does provide a general price list on its website.

The platform offers pay-as-you-go rates and subscription plans to clean up your lists. Let’s start with pay-as-you-go rates.

The scheme goes as follows: the more you verify, the lower the cost. For 5,000 credits, you’ll pay $40.00 (that’s $0.008 per email), and for 10,000, you’ll pay $50.00 (that’s already $0.005 per email).

The Enterprise package includes more than 2,000,000 credits; to find out the pricing for that amount, you need to contact their sales department.

As for subscription plans, the list cleaning offer starts at 1,000 emails, for which you will pay $10.00 per month (or $8.00 if you pay annually).

If, on the other hand, you have more extensive needs and want to clean a list that has more than 1,000,000 emails, you qualify for the Enterprise plan. And again – you need to contact their sales department to find out how much such a service costs.

What else should you know about NeverBounce pricing?

First, they offer free credits to get you started, which is helpful if you’re just testing things out.

As your email verification needs grow, volume discounts are available, which can lower costs for high-volume users.

A nice feature is the free deduplication service, which automatically cleans out duplicates and syntax errors at no extra cost.

NeverBounce offers free list analysis for list health checks. This service is useful if you want to understand list quality upfront.

Does NeverBounce pricing have any drawbacks?

NeverBounce’s pricing structure has attractive features, but consider the other side of the coin:

1. The significant discounts only apply at higher usage tiers (up to 2 million credits), which may be out of reach for smaller businesses or those with less frequent verification needs.
2. For businesses with ongoing needs, the pay-as-you-go model might become expensive over time, mainly if you verify emails regularly but don’t quite reach the volume needed for discounted rates.
3. While each plan includes all features, this could feel unnecessary for those who only need basic verification and don’t require advanced options like list analysis or deduplication.
4. Unlike some competitors, NeverBounce doesn’t seem to offer lower prices for long-term commitments.

While NeverBounce offers a straightforward approach, it may feel somewhat limiting for small-to-medium businesses needing fewer credits or more customizable plans.
