## 从这里开始
**新应用？** 首先从[目录](./resources/transactional-email-catalog.md)开始，规划您的应用需要哪些邮件（密码重置、验证等），然后在发送第一封邮件之前设置[送达能力](./resources/deliverability.md)（DNS 身份验证）。
**垃圾邮件问题？** 首先检查[送达能力](./resources/deliverability.md)——身份验证问题是最常见的原因。Gmail/Yahoo 会拒绝未经身份验证的电子邮件。
**营销邮件？** 遵循此路径：[Email Capture](./resources/email-capture.md)（收集同意）→ [Compliance](./resources/compliance.md)（法律要求）→ [Marketing Emails](./resources/marketing-emails.md)（最佳实践）。
**生产环境就绪的发送？** 增加可靠性：[Sending Reliability](./resources/sending-reliability.md)（重试 + 幂等性）→ [Webhooks & Events](./resources/webhooks-events.md)（追踪送达）→ [List Management](./resources/list-management.md)（处理退信）。
