Overview

Sending 1,500 cold emails a day for around 50 meetings a month doesn't require a massive budget, and Wesley Hoang breaks down exactly what it costs to build.

The math starts with the 10-emails-per-inbox rule: hitting 1,500 sends a day means running 150 active inboxes across 50 domains, three per domain, to keep domain reputation intact. The monthly budget lands around $1,500 total: roughly $50 for domains, $540 for inboxes including backups, and $99 for Smartlead, plus data tools and AI agents, which works out to about $30 per booked meeting.

Smartlead does the heavy lifting on inbox rotation, warm-up automation, and analytics, while lead sourcing shifts depending on the audience, Apollo, AI Ark, Clutch, or D7 depending on whether the target is SMBs, agencies, or e-commerce. Clay handles data enrichment and personalization at scale. One rule worth flagging: standard CRMs aren't built for high-volume, multi-domain sending and will likely get domains flagged.

At this volume, the benchmarks to hit are a 2% reply rate and 25% positive replies, landing in the 40 to 50 meetings a month range. The most common ways this breaks: skipping the 2 to 3 week warm-up period, ramping sending volume too fast instead of stepping it up gradually, and leaning on infrastructure to cover for weak copy when the hook, body, and CTA are still what actually gets the meeting.
