Domain costs
.COM domains cost $8 to $15 per domain per year. At 5 domains, that is $40 to $75/year. At 20 domains, that is $160 to $300/year.
Email hosting costs
Google Workspace Business Starter: $7/user/month. With three accounts per domain and five domains, that is 15 accounts at $7 each = $105/month. Microsoft 365 Business Basic: $6/user/month, slightly less.
Warmup tool costs
Most warmup tools charge $3 to $5 per account per month. At 15 accounts, that is $45 to $75/month. Some sending tools include warmup in their pricing.
Sending tool costs
Instantly, Smartlead, and Saleshandy offer plans ranging from $30 to $200/month depending on account limits and features. A typical setup runs $50 to $100/month.
Data costs
Apollo.io free tier provides limited credits. Paid plans start at $49/month. ZoomInfo is significantly more expensive ($10,000+/year). For most small to mid-size operations, Apollo at $49 to $99/month is sufficient.
Email verification costs
NeverBounce, ZeroBounce, and similar tools charge $0.003 to $0.008 per verification. Verifying 5,000 emails per month costs $15 to $40.
Total monthly cost breakdown
For a small operation (5 domains, 15 accounts, 500 emails/day): $250 to $400/month. For a medium operation (15 domains, 45 accounts, 1,500 emails/day): $600 to $1,000/month. For a large operation (40 domains, 120 accounts, 4,000 emails/day): $1,500 to $3,000/month.
Simplifying the cost structure
Warm Inboxes bundles domains, hosting, authentication, and warmup into a single per-inbox price. This simplifies budgeting and eliminates the operational overhead of managing multiple vendor relationships.
The ROI context
Even at $1,000/month for a medium operation, if cold email generates 20 qualified meetings per month and a single closed deal is worth $10,000+, the ROI is overwhelming. Cold email infrastructure is one of the highest-return investments in B2B sales.
