The Email Blacklist Verification API offers a comprehensive solution for validating email addresses in real time, helping businesses and developers maintain clean databases, improve deliverability, and reduce bounces. Using advanced analysis, the service checks multiple aspects of an email address to determine whether it is valid, active, and reliable before it is used in critical processes such as registrations, mass mailings, or marketing campaigns.
The verification process includes confirming the correct email format, ensuring that it complies with established standards. The API then checks whether the domain actually exists and has MX records configured, which is essential for receiving emails effectively. In addition, integration with Gravatar is performed, allowing images and profiles to be associated with addresses, providing an additional layer of validation.
In short, this API is an indispensable tool for any organization that relies on email as a communication channel. It offers speed, accuracy, and security, ensuring that each validated email address meets the quality and reliability standards required in modern digital environments.
Verify emails in real time by checking format, domain, MX records, gravatar, and blacklists, ensuring clean and reliable data.

The Email Check endpoint returns data regarding the validity of an email address, including its format, domain existence, MX records, Gravatar profile, and whether the email is listed on any blacklists.
Key fields in the response include "valid" (boolean), "domain" (string), "mx_records" (boolean), "gravatar" (object), and "blacklisted" (boolean), providing a comprehensive overview of the email's status.
The Email Check endpoint accepts parameters such as "email" (the email address to verify) and optional flags for additional checks, allowing users to customize their verification requests.
The response data is structured in a JSON format, with each key representing a specific aspect of the email verification process, making it easy to parse and utilize programmatically.
The data is sourced from various email validation databases, DNS records for domain checks, and Gravatar services, ensuring a comprehensive and reliable verification process.
Data accuracy is maintained through regular updates from trusted sources, automated checks for domain and MX record validity, and continuous monitoring of blacklist databases.
Typical use cases include validating email addresses during user registrations, cleaning email lists for marketing campaigns, and ensuring reliable communication in business processes.
If the response indicates partial or empty results, users should implement fallback mechanisms, such as prompting users to re-enter their email or providing alternative contact methods for verification.

To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
