Deliverability Check API

The Deliverability Check API ensures email accuracy by validating addresses. Its syntax, domain, and mailbox checks enhance deliverability and communication reliability.

About the API:  

The Deliverability Check API is a critical tool in the digital communication landscape, designed specifically to improve the accuracy and deliverability of email communications. In the contemporary era, where email serves as the primary medium for personal and professional interactions, the importance of maintaining a reliable and efficient communication channel cannot be overstated.

Email verification, a fundamental step in the email communication process, seeks to validate the authenticity of email addresses before sending messages. Inaccurate or invalid email addresses pose problems such as bounced messages, which can negatively affect the sender's reputation and overall email deliverability. The Deliverability Check API addresses these issues systematically and automatically, providing a comprehensive solution for email address verification.

The API works through a series of meticulous checks and validations that ensure a thorough assessment of the integrity of an email address. It incorporates syntactic verification to examine the structure of the email address, confirming its adherence to standard syntax rules. Domain validation is another key component, which verifies the existence, activity and functionality of the email domain to minimize problems related to domain errors.

In addition to domain verification, the API performs mailbox validation, checking the specific mailbox associated with the email address. This process confirms the mailbox's reachability and ability to receive emails, further improving the accuracy of email delivery. The API goes beyond the basics by incorporating mechanisms to detect disposable email addresses, often associated with temporary and potentially non-serious activities.

One of the notable advantages of the Deliverability Check API is its ease of integration into various applications, websites or systems where email verification is essential. With comprehensive documentation and support, users can seamlessly incorporate the API into their workflows, contributing to the accuracy of email databases and improving the effectiveness of email marketing campaigns.

In short, the Deliverability Check API is a reliable and indispensable solution for ensuring accurate and effective email communications in today's dynamic digital environment.

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.

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."

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.
