## Instantly

Instantly 把自己定位为其自身增长背后的外联系统，产品围绕三大支柱组织：寻找线索、启动活动、让邮件不进垃圾箱。线索获取与数据套件涵盖 AI 客户发现、线索数据库、验证与网站访客识别；外联与互动侧则提供序列器、CRM、自动化、AirMail 邮箱账户和收件箱投放测试。主要用户是代理商、自由职业者、创始人和销售团队。让它区别于普通邮件序列器的是智能体层。Instantly 提供一系列具名智能体——AI 销售智能体、回复智能体、线索发现智能体、送达率智能体、合作智能体、投资智能体、招聘智能体和用户研究智能体——可以组合成一支全天候的收入团队。Instantly AI 还能作为助手，根据提示词搭建活动、个性化文案并生成线索列表。当线索访问你的网站、回复或预约会议时，工作流会自动路由、打标签并触发后续活动。报表面向收入而非虚荣指标，追踪商机、管道、转化和已完成收入，并自动暂停表现不佳的活动。Instantly 可与现有工具栈连接，也可从 ChatGPT 驱动（Claude 标注为即将推出）。价格为按发送量、邮箱数量和线索额度分层的付费方案。

**定价与套餐:** 提供免费试用入口的付费方案；价格随邮件发送量、已连接邮箱数和线索库额度扩展。具体档位见 instantly.ai/pricing。

- **Chat with PDFs and web pages:** Upload documents or point the assistant at a page to extract answers, summaries, and key points instead of reading everything yourself.

- **Automations and campaigns:** Set up recurring responses, scheduled follow-ups, and AI-assisted campaigns to cut repetitive sending work.
