How much does it cost to run cold email campaigns at scale?
Running cold email at scale costs $500 to $5,000 per month depending on prospect volume, sequence complexity, and tooling. For 10,000 to 50,000 prospects monthly you typically need a sending infrastructure layer ($100 to $300), a sequencing platform ($200 to $800), and data enrichment ($200 to $1,500). OnyxSend bundles prospect research, multi-channel sequences, and meeting booking into one workflow, cutting per-booked-meeting costs by eliminating the tool stack and keeping deliverability high across every send.
Evidence and detail
- Teams sending 10,000+ cold emails monthly report 15 to 35% cost reductions when consolidating research, sequencing, and booking into a single platform versus stitching three tools together.
- Average reply rates on well-segmented cold email sequences run 3 to 8%; at 50,000 prospects per month that produces 1,500 to 4,000 replies and 200 to 600 qualified meetings without paid ad spend.
- Deliverability failures account for up to 40% of wasted outreach budget; domain warming, inbox rotation, and sequence throttling built into the sending layer directly protect pipeline value.
