MailboxValidator Single Email Validation API FAQs

The Single Email Validation API is a powerful tool that validates individual email addresses to identify and eliminate invalid or unreachable email addresses. It checks various aspects such as email syntax, MX record, server connection, greylisting, and more to provide accurate validation results.

The API thoroughly examines the structure and format of an email address, checking for common syntax errors such as missing or misplaced characters, invalid symbols, and incorrect formatting. It ensures that the email address follows the standard syntax rules.

The API verifies the MX (Mail Exchanger) record associated with the email address domain to ensure that it points to a valid mail server. It also establishes a connection with the server to validate its responsiveness, ensuring that emails can be sent to and received from the address successfully.

Yes, the Single Email Validation API identifies free email services (e.g., Gmail, Yahoo) and disposable email services (temporary email providers commonly used for spam or fraudulent activities). This helps businesses avoid engaging with unreliable or untraceable email sources.

Suppressed email addresses are typically those opted out of receiving emails or marked as "do not contact." The API checks if an email address is suppressed to respect user preferences and comply with email marketing regulations. Additionally, it identifies role-based email addresses (e.g., [email protected], [email protected]) that may have limited engagement potential.

The API returns detailed validation results for a single email address, including checks for syntax, MX records, server connection, and classifications such as free, disposable, or role-based emails. The results are provided in either JSON or XML format.

Key fields in the response include "email_address," "is_free," "is_syntax," "is_smtp," "is_verified," "is_disposable," "is_role," and "mailboxvalidator_score." These fields provide insights into the validity and characteristics of the email address.

The response data is structured as a JSON or XML object, with key-value pairs representing various validation results. Each field indicates a specific aspect of the email's validity, making it easy to parse and utilize programmatically.

The endpoint provides information on email validity, including syntax correctness, server connectivity, greylisting status, and classifications like disposable or high-risk emails. This comprehensive data helps users assess the reliability of an email address.

The primary parameter for the endpoint is the email address to be validated. Users should ensure the email is formatted correctly. No additional parameters are required, simplifying the request process.

Users can analyze fields like "is_verified" and "is_smtp" to determine if an email is valid and reachable. The "mailboxvalidator_score" can help prioritize follow-up actions based on the risk level associated with the email address.

Data accuracy is maintained through continuous updates and checks against known email service providers and validation techniques. The API employs various methods to ensure that the results reflect the current status of the email address.

Typical use cases include email marketing, user registration validation, and fraud prevention. Businesses can use the API to clean their email lists, ensuring they only engage with valid and reachable addresses, thus improving campaign effectiveness.

General FAQs

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.

Prices are listed in USD (United States Dollar), EUR (Euro), CAD (Canadian Dollar), AUD (Australian Dollar), and GBP (British Pound). We accept all major debit and credit cards. Our payment system uses the latest security technology and is powered by Stripe, one of the world’s most reliable payment companies. If you have any trouble paying by card, just contact us at [email protected]

Additionally, if you already have an active subscription in any of these currencies (USD, EUR, CAD, AUD, GBP), that currency will remain for subsequent subscriptions. You can change the currency at any time as long as you don't have any active subscriptions.

The local currency shown on the pricing page is based on the country of your IP address and is provided for reference only. The actual prices are in USD (United States Dollar). When you make a payment, the charge will appear on your card statement in USD, even if you see the equivalent amount in your local currency on our website. This means you cannot pay directly with your local currency.

Occasionally, a bank may decline the charge due to its fraud protection settings. We suggest reaching out to your bank initially to check if they are blocking our charges. Also, you can access the Billing Portal and change the card associated to make the payment. If these does not work and you need further assistance, please contact our team at [email protected]

Prices are determined by a recurring monthly or yearly subscription, depending on the chosen plan.

API calls are deducted from your plan based on successful requests. Each plan comes with a specific number of calls that you can make per month. Only successful calls, indicated by a Status 200 response, will be counted against your total. This ensures that failed or incomplete requests do not impact your monthly quota.

Zyla API Hub works on a recurring monthly subscription system. Your billing cycle will start the day you purchase one of the paid plans, and it will renew the same day of the next month. So be aware to cancel your subscription beforehand if you want to avoid future charges.

To upgrade your current subscription plan, simply go to the pricing page of the API and select the plan you want to upgrade to. The upgrade will be instant, allowing you to immediately enjoy the features of the new plan. Please note that any remaining calls from your previous plan will not be carried over to the new plan, so be aware of this when upgrading. You will be charged the full amount of the new plan.

To check how many API calls you have left for the current month, refer to the β€˜X-Zyla-API-Calls-Monthly-Remaining’ field in the response header. For example, if your plan allows 1,000 requests per month and you've used 100, this field in the response header will indicate 900 remaining calls.

To see the maximum number of API requests your plan allows, check the β€˜X-Zyla-RateLimit-Limit’ response header. For instance, if your plan includes 1,000 requests per month, this header will display 1,000.

The β€˜X-Zyla-RateLimit-Reset’ header shows the number of seconds until your rate limit resets. This tells you when your request count will start fresh. For example, if it displays 3,600, it means 3,600 seconds are left until the limit resets.

Yes, you can cancel your plan anytime by going to your account and selecting the cancellation option on the Billing page. Please note that upgrades, downgrades, and cancellations take effect immediately. Additionally, upon cancellation, you will no longer have access to the service, even if you have remaining calls left in your quota.

You can contact us through our chat channel to receive immediate assistance. We are always online from 8 am to 5 pm (EST). If you reach us after that time, we will get back to you as soon as possible. Additionally, you can contact us via email at [email protected]

To give you the opportunity to experience our APIs without any commitment, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost. This trial can be used only once, so we recommend applying it to the API that interests you the most. While most of our APIs offer a free trial, some may not. The trial concludes after 7 days or once you've made 50 requests, whichever occurs first. If you reach the 50 request limit during the trial, you will need to "Start Your Paid Plan" to continue making requests. You can find the "Start Your Paid Plan" button in your profile under Subscription -> Choose the API you are subscribed to -> Pricing tab. Alternatively, if you don't cancel your subscription before the 7th day, your free trial will end, and your plan will automatically be billed, granting you access to all the API calls specified in your plan. Please keep this in mind to avoid unwanted charges.

After 7 days, you will be charged the full amount for the plan you were subscribed to during the trial. Therefore, it’s important to cancel before the trial period ends. Refund requests for forgetting to cancel on time are not accepted.

When you subscribe to an API free trial, you can make up to 50 API calls. If you wish to make additional API calls beyond this limit, the API will prompt you to perform an "Start Your Paid Plan." You can find the "Start Your Paid Plan" button in your profile under Subscription -> Choose the API you are subscribed to -> Pricing tab.

Payout Orders are processed between the 20th and the 30th of each month. If you submit your request before the 20th, your payment will be processed within this timeframe.
