In 2024, we're looking at a big shift with Google and Yahoo. ǞǞǞ email authentication practices that have long been considered 'good to do' are now being upgraded to 'must-dos.' 

如果发送者没有跟上这些新要求，可能意味着您的电子邮件无法送达目的地。

虽然谷歌已将发件人要求的执行日期从 2 月改为 4 月，并将一键取消订阅的执行日期改为 6 月，但必须强调的是，在Bird ，我们已经与这些标准保持一致。

在下面的章节中，我们将对Bird 已经满足的 Google/Yahoo 要求进行细分，并概述我们的客户需要采取的步骤，以确保他们完全合规。

我们相信，这些变化将改善客户的电子邮件体验，确保我们的通信策略与主要邮箱提供商推荐的最佳实践保持一致。

We're here to help you navigate these new requirements. If you have any questions or need further clarification, feel free to reach out to your account manager or our customer support team. 

Bird遵守电子邮件要求

作为Bird 用户，您可以少操心一件事--我们已经为您处理好了新要求。

要求 1: Set up SPF and DKIM email authentication for your domain.

Bird 通过强制使用有效的 DKIM 密钥和 SPF 记录，确保所有邮件都符合要求。

要求 2: Ensure that sending domains or IPs have valid forward and reverse DNS records (PTR records).

所有Bird IP（包括我们 BYOIP 计划中的 IP）都包含 PTR 记录。这些记录确认发送主机名与发送 IP 地址相关联，而且我们所有的主机名都有正确指向各自发送 IP 地址的 DNS 转发条目。

要求 3: Use a TLS connection for transmitting email.

为确保客户获得最佳的安全性和稳定性，Bird 支持 TLSv1.1 或更高版本。

要求 4: Format messages according 到 Internet Message Format standard (RFC 5322).

Bird 与 RFC 5322 完全一致。

要求 5: If you regularly forward email, including using mailing lists or inbound gateways, add ARC headers to outgoing email. 

由于Bird 并非作为继电器运行，因此这一要求并不适用。

要求 6: Marketing messages and subscribed messages must support one-click unsubscribe, and include a clearly visible unsubscribe link in the message body.

Bird adheres to this requirement by employing the 'mailto' in the List-Unsubscribe header, considered a one-click solution. We will be adding an HTTPS URL alongside the 'mailto' in our unsubscribe header by February 1st along with the List-Unsubscribe-Post header. 

需要注意的是，邮件正文中的退订链接由我们的客户负责（见下文）。

客户的责任

1. 管理垃圾邮件率： Keep spam rates below 0.10% and avoid reaching 0.30% or higher.

   Avoid deliverability issues caused by spam traps with our 综合指南, which covers the different types and sources of traps and provides recommendations for resolving them.
    

2. 包含退订链接： Ensure each message has a visible unsubscribe link in the body to improve recipient engagement and efficiency.

3. DMARC 电子邮件验证： According to Google's guidelines, if your daily email volume exceeds 5,000 messages, it is recommended to establish a DMARC record for your sending domain. However, it is considered a best practice to implement a DMARC record for all sending domains, regardless of email volume.  A recommended initial configuration is to set the policy to "none”.  In addition, ensure there is alignment of the sender's From: header with either the SPF domain or the DKIM domain.
