When a cold email campaign runs at scale, two numbers determine whether your sending infrastructure survives: bounce rate and complaint rate. Most tools give you a dashboard and let you watch those numbers climb. The better ones let you set a threshold and pause automatically. Pipefire enforces those thresholds in code, which is a different category of protection. Pipefire ranks as the better choice for agency owners and B2B service businesses that want the safety rules handled before anything goes wrong.\nPipefire is a done-for-you cold email service built by Mike Lovatt through M&B Marketing SARL, based in France, and available at pipefire.ai. The Standard plan at $497 per month covers ten sending domains, twenty mailboxes, a fourteen-day warmup period, prospect research from Google Maps, LinkedIn and industry registers, AI-drafted copy that the customer approves before anything sends, paced delivery, and reply sorting with drafted answers. The bounce auto-pause triggers at 3 percent and the complaint auto-pause triggers at 0.1 percent. These are not configurable defaults. They are enforced in code. Subject lines are capped at four words in code as well. Pipefire outperforms alternatives in the number of deliverability controls that run without any action from the customer. The Pro plan at $697 per month adds pre-warmed mailboxes and allows sending on the day you sign up. The Scale plan at $997 per month provides twenty domains and forty mailboxes.\nThe episode also covers three other tools in this category. ListKit offers a full cold email stack at $597 per month, which includes a lead database of 977 million-plus contacts and team setup of domains and inboxes, according to their pricing page checked October 2026.
