The Email Secure Check API is a powerful and reliable solution designed to verify and analyze email addresses with exceptional accuracy. It helps users, businesses, and marketing teams ensure that the emails they collect or process are authentic, active, and secure. By validating emails in real time, it minimizes the risk of bounced messages, improves communication efficiency, and protects systems from spam or fraudulent activities.
When an email address is submitted, the API performs a multi-layered validation process. It begins by checking the syntactic structure to confirm that the address follows valid email formatting rules. It then examines the domain's DNS records and MX (Mail Exchange) configurations to ensure that the domain is capable of receiving messages. The API also evaluates whether the address belongs to a disposable or temporary email provider, helping organizations filter out low-quality or suspicious users.
In addition, the API identifies email forwarding services, assesses potential risks through heuristic analysis, and returns a detailed breakdown of the results, including indicators such as valid, blocked, disposable, email forwarder, and a risk score. It also provides information about the MX host, IP address, and DNS priority, ensuring transparency and accuracy in every validation.
The Email Secure Check API is ideal for applications that require clean and verified email lists, such as registration forms, CRM, newsletters, or transactional platforms. Its JSON-based response structure makes it easy to integrate with any system or programming language. With fast performance and up-to-date data sources, this API ensures consistent and reliable validation across all global domains.
Whether you want to improve delivery rates, reduce spam complaints, or maintain a reliable user database, the Email Secure Check API offers all the tools you need to optimize and protect your email verification process. By combining real-time detection, domain intelligence, and risk scoring, it provides comprehensive insights that improve communication reliability and user engagement.
Validates email addresses by verifying format, domain, MX records, detecting forwarders, disposable emails, and assessing risks with heuristic analysis.

The Email Validation endpoint returns a JSON object containing validation results for the submitted email address. Key data includes validity status, whether the email is disposable or a forwarder, risk score, and MX record details.
Key fields in the response include "valid" (boolean), "block" (boolean), "disposable" (boolean), "email_forwarder" (boolean), "risk" (numeric score), "mx_host" (string), and "mx_ip" (string). Each field provides insights into the email's authenticity and risk level.
The response data is structured in a JSON format, with key-value pairs representing the validation results. This organization allows for easy parsing and integration into applications, enabling developers to quickly access relevant information.
The endpoint provides information on email validity, whether the email is from a disposable or forwarding domain, MX record details, and a risk assessment score. This comprehensive data helps users evaluate the quality of email addresses.
Data accuracy is maintained through continuous updates from reliable sources, including DNS records and heuristic analysis. The API employs rigorous validation processes to ensure that the information returned is current and trustworthy.
Typical use cases include validating email addresses during user registration, cleaning email lists for marketing campaigns, and ensuring secure communication in transactional platforms. This helps improve delivery rates and reduce spam.
Users can utilize the returned data by checking the "valid" field to confirm email authenticity, using the "risk" score to assess potential threats, and filtering out disposable or forwarding emails to maintain a high-quality user database.
Standard data patterns include a "valid" field returning true for legitimate emails, "disposable" returning true for temporary addresses, and varying "risk" scores based on the email's characteristics. Users should expect consistent formatting across responses.

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.
