How we stopped paying $97/month for Instantly & built our own outbound sender system instead.

A few weeks ago I looked at our outbound workflow and realized we were paying roughly $97/month for Instantly & which was, for what we were actually using it for, mostly acting as a fancy wrapper around SMTP/IMAP. We needed multiple Google Workspace inboxes to rotate through, randomized delays, per-inbox sending limits, basic personalization, and, most importantly, automatic follow-up stopping when someone replies. So I decided to just build the thing we needed ourselves. The actual sending

痛点：冷邮件外发工具订阅费高（$97/月）且功能常只是 SMTP/IMAP 包装，技术团队希望自托管、可控成本并掌握发送逻辑。

目标用户：技术型 SaaS 团队、增长/外呼团队、独立开发者，尤其是已有多个 Google Workspace 邮箱并愿意自托管的人。

证据：we were paying roughly $97/month for Instantly & which was, for what we were actually using it for, mostly acting as a fancy wrapper around SMTP/IMAP. So I decided to just build the thing we needed ourselves. The actual sending side is pretty small.

变现：开源核心 + 付费托管/一键部署；或按 $19-39/月提供低价自托管替代方案；也可卖代码模板、部署支持、warmup/送达率配置服务。

MVP：2 周内做最小可用版：连接多个 Google Workspace 邮箱，SMTP 轮换发送、随机延迟、每日限额、CSV 导入、简单日志，并用 IMAP 检测回复后自动停止跟进。

竞品：Instantly、Smartlead、Lemlist、Woodpecker、Saleshandy、Mailshake、Mailwarm

摘要：原帖作者因每月 $97 的 Instantly 费用，自己用 Python + SMTP/IMAP 搭建外发系统，实现多邮箱轮换、随机延迟、限额和回复自动停止跟进。这验证了冷邮件外发工具存在真实付费市场，也暴露了自托管替代需求，但竞品密集且作者本身选择自建而非付费，机会更偏成本替代而非全新需求。
