Use ZeroBounce's email validation API to increase your email marketing ROI!
Remove invalid email addresses from your list using our unique email verification scrubbing system to prevent email bounces.
Our API will protect your reputation by reducing your bounce rate, remove bad emails to improve overall inbox delivery metrics, and we have a 98% accuracy guarantee.
Below you will find the documentation on our API, it's very easy to use and requires SSL.
The response time for our API is between one second and 70 seconds. Since API's are meant to be fast by nature, we limit the amount of time we spend validating an email address. So if we encounter a slow mail server or a mail server with a greylisting algorithm you will get an unknown result. You can always re-validate those conditions, uploading a file to the bulk email validator.
On average 96-98% of all domains will return in 1 to 5 seconds, there are a handful of domains that run off Postfix/Dovecot that have a 20 second connection time for real-time validations and a very small fractional percentage of other domains that are very slow to respond to SMTP inquires. All the major ISP will return in 1 to 3 seconds, which is usually the majority of most email distribution.
The API will return these results in a JSON format using the "Validate" method.

Zyla API Hub is, in other words, an API MarketPlace. An all-in-one solution for your developing needs. You will be accessing our extended list of APIs with only your user. Also, you won't need to worry about storing API keys, only one API key for all our products is needed.
Prices are listed in USD. 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 with paying by card, just contact us at [email protected]
Sometimes depending on the bank's fraud protection settings, a bank will decline the validation charge we make when we attempt to be sure a card is valid. We recommend first contacting your bank to see if they are blocking our charges. If more help is needed, please contact [email protected] and our team will investigate further
Prices are based on a recurring monthly subscription depending on the plan selected — plus overage fees applied when a developer exceeds a plan’s quota limits. In this example, you'll see the base plan amount as well as a quota limit of API requests. Be sure to notice the overage fee because you will be charged for each additional request.
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.
Just go to the pricing page of that API and select the plan that you want to upgrade to. You will only be charged the full amount of that plan, but you will be enjoying the features that the plan offers right away.
Yes, absolutely. If you want to cancel your plan, simply go to your account and cancel on the Billing page. Upgrades, downgrades, and cancellations are immediate.
