Product Details

What is WhoisXML Email Verification API?

Email Verification API is a tool that allows verifying the validity of email addresses through API calls using a variety of programming languages (PHP, Node.js, Python, Flask, and Express.js). Developers and product architects can use the API to integrate email-checking capabilities into existing software and applications.

Email Verification API helps with the business tasks identified below.

Cleaning Up Email Distribution Lists

Nonexistent email addresses can hurt an organization’s email-sending reputation with high bounceback rates. At worst, companies sending emails to such addresses could get tagged as spammers and be consequently blocked on current and prospective clients’ networks. Email Verification API can help users get rid of email addresses that don’t meet IETF standards, are disposable, and don’t have corresponding mailboxes or mail servers.

Reducing Possibly Bogus Registrations

While not all temporary email address users are up to something bad, some might be out to abuse free trial offers. Email Verification API is connected to a comprehensive disposable domain database that’s updated daily, giving it the ability to spot disposable email addresses in real-time so these won’t get into users’ subscriber bases.

Avoiding Spam Traps

Many companies employ spam traps, typically by setting up catch-all email addresses. But that can be bad for senders in that their messages might not get to their intended recipients. Email Verification API is capable of detecting catch-all addresses.

WhoisXML Email Verification API provides additional value to our corporate email security

Vetted Review

Use Cases and Deployment Scope
We use WhoisXML Email Verification API to derive an added functionality from the email security system we currently have. In particular, WhoisXML Email Verification API enhanced the capability of our spam filters, as it automatically flags messages from disposable email addresses, which spammers could use.
Pros and Cons
  • WhoisXML Email Verification API obtains its disposable email detection capabilities from a disposable email domain database that monitors most disposable email providers regularly.
  • WhoisXML Email Verification API is compatible with most spam filtering solutions and other email security systems. It is also available as a Splunk application, so compatibility wasn’t an issue for us.
  • We had to avail ourselves of the custom plan because we have a pretty large user base, and each user receives hundreds of emails per day. We were able to come up with a reasonable agreement, in any case.
Likelihood to Recommend
We use WhoisXML Email Verification API for the additional value it provides to our corporate email security, and we recommend that most organizations do the same. Disposable email services may help protect the privacy of their users, but in the corporate setting, receiving emails from these domains may not be safe. So, aside from flagging emails from domains categorized as spam, we wanted our spam filtering system to be stricter and include disposable email addresses.
Most Important Features
  • Disposable email address detection
  • Generic email address detection
  • Mail server existence
  • Mailbox existence
Return on Investment
  • Enhances spam filtering, which helps keep malicious emails away. Having someone in our network falling for spam or phishing emails could be far more expensive in the long run.
  • Detects emails from disposable email domains, which are non-work-related.

Email Verification API benefits our email marketing efforts

Marketing & Advertising Company, 1-10 employees

Vetted Review
Verified User
Use Cases and Deployment Scope
We launched one of our websites a year ago with the Email Verification API already integrated into the signup process. We wanted our users to be able to make sure they type in the correct email address all the time. We also wanted to screen our subscribers’ email addresses and ensure that those that make it to our mailing list are valid and existing. Email verification benefits both our subscribers and us. On our part, we can reach out to them through email to keep them informed of relevant information about their subscriptions.
Pros and Cons
  • It helps our system automatically tell users when they mistype their email addresses or provide nonexistent ones. It helps improve customer experience since they aren’t left assuming they entered the correct email address, only to wait for responses.
  • I like that the vendor made Email Verification API available in several languages and client libraries— PHP, Node.js, Python, Flask, and Express.js. For the dev team, it took a weight off our shoulders in terms of coding.
  • There is a maximum number of requests per second, which is 10. While this is a reasonable number, and we haven’t had any issue after a year of using the API, that is something that dev teams should take note of.
Likelihood to Recommend
We initially used it because we know that our target website visitors are prone to mistyping email addresses. We wanted to provide a good experience for them. Over time, we realized that it also benefited our email marketing efforts. So if you’re going to validate users’ email addresses upon signup, Email Verification API can help.
Most Important Features
  • Syntax check
  • Mail server existence
Return on Investment
  • Decrease in email bounce rates and, therefore, less likelihood of getting tagged as a spammer.
  • Good customer signup experience.
