nvoke - a lead finder that asks the mail server if every email is real (my first app on Windows, Mac and Linux)

Hey r/SideProject . I just launched nvoke and wanted to share it here first. It's a lead finder. You type a kind of company and a place, like "dentists" and "Austin, TX". nvoke finds the companies, reads their own websites today (contact, about, team, imprint pages), and then asks each mail server if the address actually exists. You only pay for the emails that work. I didn't want another database someone scraped last year. I wanted the addresses companies publish themselves, checked rig

AI 分析

痛点:做冷外联的销售和中小团队需要"现在仍然有效"的公司公开邮箱,以避免退信、避免购买过期爬取数据库。

目标用户:做冷邮件的销售、外贸和本地服务获客的小团队,以及需要批量找线索的 AI Agent 开发者

证据:You only pay for the emails that work.(50 verified emails a month are free. Paid starts at $5 for 1,000.)

变现:按"验证成功邮箱数"计量收费(约 $0.005/封)+ 订阅套餐;对 Agent 开发者按 API、MCP 调用量计费

MVP:两周版:输入行业+城市 -> 抓取目标公司官网 contact、about、imprint 页面提取邮箱 -> 实时 SMTP 握手验证 -> 只对验证通过的结果计费,Stripe 按量结算 + 一个简单 REST 接口;桌面端和 MCP 留到后续

竞品:Hunter.io、Apollo.io、Snov.io、Anymail Finder、Findymail、NeverBounce、ZeroBounce

摘要:独立开发者发布 nvoke:输入"行业 + 地点",抓取公司官网当天公开的邮箱并直接向邮件服务器做 SMTP 验证,只为有效邮箱付费,每月 50 个免费,$5 可买 1000 个,同时提供 REST API 和 MCP。帖子是作者自述的发布推广,没有任何第三方用户的付费反馈或收入数据,因此只能算供给侧信号而非需求验证。邮件查找+验证赛道已被 Hunter、Apollo、ZeroBounce 等占据,$5/1000 的定价也说明单价被压得极低、利润空间有限。
