如何通过API检测邮件地址？

我们的 邮件地址验证API 可以轻松嵌入现有网站或者应用程序（包括网站内容管理及发布系统，如Drupal,Typo3, WordPress或者Joomla）的Javascript、PHP、Java、C#、VB和NET-Code内。作为结果，API将反馈 每一个邮件地址的可投递性状态。

我们的多级验证程序可以为您完整检测每一个邮件地址并包含以下所有检测：

• 语法验证 (根据当前的IETF/RFC标准)
• DNS验证，包含MX记录检测
• 识别临时 一次性邮件地址
• 识别拼写错误的域名以防止 误植域名
• SMTP连接检测
• SMTP临时性错误检测
• 收件人邮箱存在状态检查
• Catch-All检测
• 灰名单检测

我们保证，在整个检测过程中，我们绝不会向收件人邮箱发送任何一封邮件。
