痛点：冷邮件营销中高退信率和角色/一次性邮箱污染会损害发件人声誉，需要批量邮箱验证与决策者邮箱过滤。

目标用户：SaaS 创始人、冷邮件外拓团队、增长营销人员、CRM 运营。

证据：bounce rates and generic inbox pollution (support@, sales@, disposable domains) were consistently hurting sender reputation. I ended up building a dedicated verification microservice with batch support (up to 100 emails per call) and server-side filters to isolate decision-maker inboxes (business_only, no_role_only, deliverable_only).

变现：按调用量订阅或 API 计费，免费额度获客；高级过滤（business_only、no_role_only）和批量验证作为付费点，可在 RapidAPI 或独立 API 上收费。

MVP：2 周内做邮箱验证 API：语法+MX+SMTP 探测、一次性域名库、角色账号识别、business_only/no_role_only/deliverable_only 过滤器、批量 100 个、RapidAPI/Stripe 按量付费。

竞品：ZeroBounce、NeverBounce、MillionVerifier、Bouncer、Hunter.io、Abstract API

摘要：发帖者因冷邮件退信率和 support@/sales@ 等污染发件人声誉，构建了批量邮箱验证微服务，支持每次 100 个检查和 business_only/no_role_only/deliverable_only 过滤，并在 RapidAPI 提供每月 100 次免费额度。帖子未展示付费用户或收入数据，且邮箱验证赛道已非常拥挤。
