Due to the nature of our classification system, we currently do not offer a disposable email provider database download option at this time. Our classification system conducts real-time checks to verify if an email address is a temporary address. Since our classification system is updated both automatically and by email analysts, results can change within minutes. Based on our internal testing, a week old disposable email database backup had a 64% accuracy rate, while a month old backup only had a 43% accuracy rate.
We have an advanced classification system that utilizes either a rule-based or a predictive decision system. Our rule-based system is pretty straight forward, we gather real-time mail server properties, data from multiple sources (many are fetched within our own nodedata.io API service), and datasets. From there, the data goes through a ruleset defined by our email analyst's configuration. If the email address is not considered a disposable email, our classification system will run the predictive decision system to determine if the email has any connection or similar properties between a disposable email provider. Also, if an disposable address has gone undetected by our system, our clients can submit a data correction request for us to review the email address. From there, our email analysts will manually verify and determine if the email address is considered a disposable.
Though a good amount of our data are fetched from thousands of disposable email providers by either our email analysts or bots.
Our disposable email provider detection service is constantly being updated, since real-time checks are conducted. Though, in some cases, we may cache certain datasets within our classification process for up to 15 minutes.
Yes. Though, please note that results may be inaccurate after some time. There are several disposable email address providers that constantly rotate between mail servers, change their mail server configuration settings, or update DNS records.
Our email detection service actually employs email analysts who detect and verify email addresses. Unlike other detection services, we simply don't just fetch a few disposable email addresses from Github or an open source disposable email blocklist and aggregate them all into one list and call it an email detection service. Instead, our service is actually based on an advanced classification system that works closely with email analysts, while at the same time, can make it's own decisions. On top of that, our email analysts are constantly refining our dataset and classification system. This means that our classification system is slowly becoming more accurate as time goes on.
In addition to that, we have a few email detection providers who actually purchased a redistribution license from us, in order for them to source our data for their products.
A public disposable block list will produce many false positive and false negative results. Disposable domain block lists or blacklists typically contains outdated domain names and are not regularly moderated. Especially with open source email blacklists, anyone can submit a request to add or remove a temporary email address and the contributor of the blacklist does not have any procedures in verifying the changes from the requests.
On top of that, disposable email block lists does not conduct real-time verification tests. For example, our disposable email detection software conducts dozens of real-time checks, such as, verifying whois records, DNS, and mail server configurations. In addition to that, we haven't come across to any domain block lists that incorporate either crawlers or actual email analysts that constantly visit a disposable email provider's webpages or API service to ensure their information is the most accurate and up-to-date.
We don't consider disposable email lists up-to-date or accurate. We like to call these lists "set it and forget it" lists, where the emails are added and are not regularly checked. Some of these emails are no longer pointed to any mail server or the domain is expired. In addition to that, the blocklist contributors does not have any formal verification process in verifying the disposable addresses and it's simply a "he said, she said" type situation.
The nodedata.io team has a strong background in cybersecurity, development, and computer networking. We've been developing cybersecurity API services since 2018 and began detecting disposable email addresses since 2022.
