The full cold email stack, handled
We don't just send emails. We engineer the entire system, from infrastructure to copy to conversations, so you get qualified calls without lifting a finger.
Sending Infrastructure
Multiple secondary domains, 20+ warmed inboxes per domain, rotating sender pools, and DKIM/SPF/DMARC dialed in. Your main domain stays untouched and your sender reputation stays clean.
Deliverability Engineering
Continuous warmup, smart sending pacing, spam-trigger detection, and inbox placement monitoring. We make sure your emails land in the primary tab, not Promotions or spam.
Lead Sourcing & Verification
We scrape Google, LinkedIn, and verified databases to build your exact ICP list. Every email is verified across multiple providers before sending, keeping bounce rates near zero.
AI Copywriting at Scale
Every email is researched and personalized to the recipient. We don't use {firstName} mail-merge tricks. The AI references their company, role, recent activity, and pain points individually.
AI Reply Handling
When prospects respond, the AI takes over the conversation. It qualifies, answers questions, handles objections, and books calls directly to your calendar. 24/7, in your tone of voice.
Live Pipeline Dashboard
Track everything in real time. Sends, opens, replies, qualified leads, booked calls, deliverability score per domain. Know exactly what's working and where the pipeline is moving.

DIY vs RespondedBy.ai
“The cold email systems built by the RespondedBy.ai team have consistently generated over 60 booked calls per month for us. What used to take an entire SDR team now runs on autopilot.”

Cold email questions, answered
No. We always send from secondary domains we register and warm up for you, never your primary domain. Your main domain stays untouched and your overall sender reputation stays clean.
