Scalable Outbound Email System Development

PHP, Java, Software Architecture, CRM, Email Marketing, API, Automation, Workflow Automation · I am looking for an experienced automation developer to build a scalable outbound email system for my company.

The system needs to handle lead imports, automated email sequences, reply detection, lead status tracking, follow-ups, CRM updates, and handoff of interested prospects to a salesperson.

The goal is a system where leads are consistently contacted and followed up with automatically while interested prospects are surfaced immediately.

You should be experienced with tools such as Instantly, Smartlead, n8n/Make, APIs, email infrastructure, CRM automation, and email deliverability.

I am not looking for someone who needs extensive direction. I will provide the required workflow and desired outcome, and I need someone capable of designing and implementing the system efficiently.

AI-assisted development is encouraged. I care about the finished system, reliability, and speed—not billable hours.

When applying, please include:

- Similar outbound systems you have built - The exact tech stack you recommend - Your estimated fixed price - Your estimated completion timeframe - What ongoing costs the system will have - A short explanation of how you would architect the system
