Resend suspended our entire SaaS email service twice because of malicious signups. Seriously reconsidering using them.

I run a multi-tenant SaaS application called Ji4, which uses Resend for transactional emails, primarily ticket acknowledgements, notifications and replies.

痛点：多租户 SaaS 依赖第三方邮件 API 时，少数恶意注册用户就可能让整个账号被暂停，导致所有合法租户的邮件功能中断，而且平台不会主动提前预警。

目标用户：使用 Resend、SendGrid、SES 等第三方邮件 API 的中小多租户 SaaS 独立开发者和小团队

证据：we've had our entire Resend account suspended twice / No proactive notification that the service had been suspended. We discovered it because our application stopped sending emails. / All legitimate customers were affected because of the actions of a handful of malicious signups. / Seriously reconsidering using them.

变现：订阅制 SaaS，按项目、发送量阶梯收费（$19–79/月）；也可做成开源自托管、商业托管版收费的模式。

MVP：两周内做一个轻量邮件发送网关，用统一 SDK 或 HTTP 代理封装，内置：①多供应商自动故障转移（主供应商失败或被停后切备用）；②退信率、投诉率、账号异常和暂停状态的监控告警；③注册环节用一次性邮箱和伪造域名黑名单，拦截滥用。

竞品：Resend、Postmark、Amazon SES、SendGrid、Cloudflare Turnstile、Fingerprint

摘要：一位 Ji4 SaaS 创始人称，一周内 Resend 账号被暂停两次，原因是恶意用户注册并伪造公司 workspace 群发欺诈邮件，平台没有任何主动通知，所有合法租户邮件功能中断，申诉需反复邮件沟通。即便关闭注册、改为人工审核 workspace、限制企业邮箱域名，服务仍未恢复。发帖人明确表示正在认真考虑弃用 Resend，但未出现具体付费报价或他人附和。
