The service provides validation of email addresses. It determines not only that an address has correct syntax and references a functional domain but also that it matches a valid account properly registered under the domain and configured to receive email. In this way, it ensures that email data submitted online or accessed from vendors represent deliverable addresses.
API methods support submission of an email address or list of addresses. For each one, the API returns a status of verified, disposable (provided by a service unusable for ongoing communications), unreachable (not connected to functional mail handlers), illegitimate, or undeliverable. Methods allow specific checks for full mailboxes, expired domains, and other common issues that prevent email delivery.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API. If you think an SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
