您是否曾经想要同时验证大量电子邮件地址？地址几乎可以来自任何地方。您的电子邮件帐户、旧数据文件或任何东西。如果您进行了调查或其他事情，并且在发送电子邮件之前，您需要验证地址。MailChecker是一款适用于(MailChecker)Windows PC的邮件检查软件，绝对可以帮到你。无论信息来源是什么，您都可以复制和粘贴数据，然后点击检查按钮来验证所有电子邮件。
用于 Windows 的邮件检查器
MailChecker是一个小而有效的实用程序，可以帮助您处理电子邮件地址。您可以直接从Microsoft Excel(Microsoft Excel)复制粘贴整个电子邮件列表。否则，您可以输入以逗号、分号、冒号、换行符甚至制表符分隔的电子邮件地址。或者，您可以改为复制文本文件的内容。
出于测试目的，我从Gmail(Gmail)中导出了我的联系人，并从CSV文件中复制了数据并将其粘贴到应用程序中。另外，我插入了一个实际上不存在的电子邮件地址。结果符合预期。
所有正确的地址都被标记为“OK”。我们故意添加的条目被标记为DNS错误。但是在连接到某些服务时出现了一些问题。这些服务不信任此应用程序，也未提供任何数据。
我在连接最流行的Outlook.com服务时遇到问题。虽然您可能会遇到类似的问题，但该程序有望与大多数服务兼容。点击检查按钮后，将弹出一个新窗口，显示验证详细信息。最后执行的操作和最终结果将显示与您选择的电子邮件地址相对应。
验证完成后，您可以将所有行复制回Excel。如果要进行另一次验证，则需要关闭应用程序并从头开始。
验证电子邮件地址
想知道该程序如何验证您的电子邮件地址？好吧，它会向您的电子邮件服务器发出SMTP请求，询问您的电子邮件地址。服务器可以回复“OK”响应或“未找到”响应，或者它可能根本不回复。如果服务器信任应用程序，它将提供响应。如果没有邮件服务器监听响应，那么您可能会看到DNS错误。
MailChecker是一个很棒的应用程序。它很小但功能强大。但是该应用程序肯定缺少一些功能。喜欢从主要联系人服务自动导入。或者在后台运行验证的能力。此外，一些流行的电子邮件提供商不信任该应用程序。如果这些问题能以某种方式解决，MailChecker会更好，更有效。

MailChecker for Windows lets you Batch validate email addresses
Ever hapрened that you’ve wanted to validate а lot of еmail addresses altogеther? The addresses can be frоm almost anywhere. Your email account, old data file or just anything. If you’ve conducted a surveу or somеthing and before sending out emails you need tо validate the addresses. MailChecker is a mail checked software for Windows PC can definitely help you out. Whatever the source of information be, you can just copy and paste the data and hit the check button to validate all the emails.
MailChecker for Windows
MailChecker is a small yet effective utility that can help you out in dealing with email addresses. You can directly copy paste the entire list of emails from Microsoft Excel. Else you can enter the email addresses separated by comma, semi-colon, colon, newline or even a tab. Or you can copy the contents of a text file instead.
For testing purpose, I exported my contacts from Gmail and copied the data from CSV file and pasted that into the application. Also, I inserted an email address that actually does not exist. The results were as expected.
All the addresses that were correct were marked to be ‘OK’. And the entry that we purposely added was marked with a DNS error. But there were some issues while connecting to some services. These services did not trust this application and no data was provided.
I had problems connection to the most popular Outlook.com service. While you may face similar issues but the program is expected to be compatible with most of the services. Once you hit the check button, a new window will pop up displaying the validation details. The last operation conducted and the final result is displayed corresponding to your chosen email address.
Once the validation has completed, you can copy all the rows back to Excel. If you want to do another validation, you need to close the application and start from the beginning.
Validate email addresses
Wondering that how does the program validates your email address? Well, it makes an SMTP request to your email server asking for your email address. The server can reply with an ‘OK’ response or a ‘not found’ response or it may not reply at all. If the server trusts the application, it will provide a response. And if there is no mail server listening to the response then you may see a DNS error.
MailChecker is a great application. It is tiny yet powerful. But the application lacks some features for sure. Like automatic import from major contact services. Or the ability to run the validation in the background. Also, some popular email providers do not trust the application. If these issues could be resolved somehow, MailChecker will be better and a lot more effective.
