金融推广App必看：如何通过邮件反垃圾解析提升海外推广效果
在金融类App的海外推广工作中，邮件营销是不可或缺的重要环节。 特别是通过Google Ads等渠道获取的国外客户，邮件送达率直接影响转化效果。
In overseas promotion of financial apps, email marketing is an indispensable component. Especially for foreign clients acquired through channels like Google Ads, email delivery rates directly impact conversion results.
一、SiteGround邮箱的基础设置
1. Basic Setup of SiteGround Email
实际上，如果你使用的是SiteGround赠送的企业邮箱，即使不解析MX记录，也可以创建和使用邮箱。不同之处在于，收件人会收到不安全提醒，邮件也容易进垃圾箱。
In fact, if you're using the enterprise email provided by SiteGround, you can create and use email accounts even without resolving MX records. The difference is that recipients will receive security warnings and emails are more likely to end up in spam folders.
当然了，把NS设置成SiteGround主机的服务器地址后，MX记录是自动解析的。
Of course, after setting the NS to SiteGround's server address, the MX records are automatically resolved.
二、SiteGround后台操作步骤
2. SiteGround Backend Operation Steps
步骤1： 先把NS设置为SiteGround主机的服务器地址。
Step 1: First set the NS to SiteGround's server address.
步骤2： 待解析生效后，登陆SiteGround官网，点击上方的"Websites"标签。
Step 2: After the resolution takes effect, log in to SiteGround's official website and click the "Websites" tab at the top.
步骤3： 再点击网站下方的"Site Tools"，进入SG的控制面板。
Step 3: Then click "Site Tools" below the website to enter SG's control panel.
三、关键的反垃圾邮件解析
3. Key Anti-Spam Email Resolution
在SG控制面板处查看解析结果：
View resolution results in the SG control panel:
① 点击左边侧边栏中的"Domain"
① Click "Domain" in the left sidebar
② 点击"DNS Zone Editor"
② Click "DNS Zone Editor"
③ 在右侧就能看到所有的域名解析记录
③ All domain resolution records can be seen on the right side
反垃圾邮件的解析记录有3条：
There are 3 anti-spam email resolution records:
• DKIM (Domain Keys Identified Mail) - 域名密钥识别邮件
• SPF (Sender Policy Framework) - 发件人政策框架
• DMARC (Domain-based Message Authentication Reporting Conformance) - 基于域名的消息认证报告一致性
四、为什么这三项技术很重要？
4. Why Are These Three Technologies Important?
SPF、DKIM和DMARC是增强电子邮件生态安全性和信任度的三种技术。为了降低邮件的可交付性风险，最好同时使用这三项技术。
SPF, DKIM and DMARC are three technologies that enhance the security and trustworthiness of the email ecosystem. To reduce email deliverability risks, it's best to use all three technologies together.
对于金融类App的推广邮件来说，这些设置尤为重要，可以显著提高邮件送达率和客户信任度。
For promotional emails from financial apps, these settings are particularly important as they can significantly improve email delivery rates and customer trust.
