Bulk Cold Email Inboxes 2026: Wholesale Pricing, Volume Discounts and Custom Orders
If you are a bulk or wholesale buyer of cold email inboxes, you already know that marketplace resellers charge a heavy markup on top of the same Google Workspace and Microsoft 365 seats you can buy direct. At Puzzle Inbox we serve agencies, lead generation companies and enterprise SDR teams that need 50, 500 or 5,000 inboxes at a time, and we publish transparent wholesale pricing so you can model your unit economics before you commit. Google Workspace inboxes start at $3 to $4.50 per inbox depending on volume, and Outlook 365 inboxes drop as low as $0.35 to $0.50 each. You can self-serve up to 833 GWS Standard, 555 GWS Warm, 7,100 Outlook Standard or 5,000 Outlook Warm per order. For custom orders beyond those thresholds, we book a call to scope domains, warmup pacing, payment terms and white-label requirements before fulfilling the order in staged batches.
Bulk Pricing Tiers (50, 100, 500, 1000+)
Wholesale pricing at Puzzle Inbox is tiered by volume across both Google Workspace and Outlook 365. The more inboxes you commit to in a single order, the lower the per-inbox cost. Below is the pricing matrix used to size bulk orders. | Tier | Inbox Count | GWS Standard | GWS Warm | Outlook Standard | Outlook Warm | |------|-------------|--------------|----------|------------------|--------------| | Starter Bulk | 50-99 | $4.50 | $5.50 | $0.50 | $0.95 | | Growth Bulk | 100-499 | $4.00 | $5.00 | $0.45 | $0.85 | | Scale Bulk | 500-999 | $3.50 | $4.50 | $0.40 | $0.75 | | Wholesale | 1000+ | $3.00 | $4.00 | $0.35 | $0.65 | Tiers apply per order, not per month, so you can stack discounts by consolidating purchases.

Google Workspace Bulk Pricing
Google Workspace is the premium tier for cold email. Bulk GWS pricing at Puzzle Inbox runs $3 to $4.50 per inbox for Standard and $4 to $5.50 for pre-warmed. The maximum self-serve quantity in a single order is 833 GWS Standard inboxes or 555 GWS Warm inboxes. Each GWS order includes domain forwarding, SPF/DKIM/DMARC configured at registrar level, and Google verification handled before delivery. Larger commitments unlock dedicated provisioning and staged delivery windows so your warmup pool ramps in waves instead of all at once.

Outlook 365 Bulk Pricing
Outlook 365 is the volume tier for cost-sensitive agencies and lead-gen shops. Bulk Outlook pricing starts at $0.35 per inbox at Wholesale tier (1,000+) and tops out at $0.50 for Starter Bulk. Pre-warmed Outlook inboxes add roughly $0.30-$0.60 per seat depending on tier. Self-serve max per order is 7,100 Outlook Standard or 5,000 Outlook Warm. Outlook is ideal when you need to send hundreds of thousands of cold emails per month at predictable per-touch cost, and the per-inbox economics make it easy to absorb domain replacement cycles.

Enterprise Volume Orders (5,000+ Inboxes)
Orders above 5,000 Outlook Warm, 7,100 Outlook Standard, 555 GWS Warm or 833 GWS Standard fall outside the self-serve flow and require a scoping call. On that call we confirm domain naming conventions, registrar split (Cloudflare vs Namecheap vs your own), warmup pacing, mailbox-per-domain ratio, and the staged delivery schedule. Enterprise volume orders typically deliver across 2-6 weeks in tranches of 500-2,000 inboxes to avoid provider abuse signals and to give your sending platform time to absorb the new sender pool.

Bulk Delivery Timeline
Bulk delivery timelines depend on inbox type and volume. Outlook Standard orders up to 1,000 inboxes deliver in 24-48 hours. Outlook orders of 1,000-7,100 inboxes deliver in 3-7 business days in staged batches. Google Workspace Standard up to 200 inboxes delivers in 2-4 business days, with 200-833 inboxes taking 5-10 business days due to Google verification limits. Pre-warmed inboxes add 14-21 days of warmup time before handoff. For enterprise orders we share a Gantt-style delivery schedule on the kickoff call.

Bulk Warmup Strategy
Warming 1,000+ inboxes at once is not a copy-paste of single-inbox warmup. Our bulk warmup strategy ramps mailboxes in cohorts of 100-250 to spread reputation signals across the provider's spam infrastructure. Pre-warmed seats arrive with 21 days of peer-to-peer warmup, positive engagement signals and inbox placement testing already complete. For self-warmed bulk orders, we recommend connecting to a warmup tool for an additional 14 days before sending cold, and capping send volume to 20 emails per inbox per day for the first month.
Use Cases: Agencies, Lead-Gen, Enterprise SDR Teams
Three buyer profiles dominate our bulk pipeline. Cold email agencies buy 500-2,000 Outlook inboxes per month to fulfill client retainers, and resell with their own SOPs and reporting layer on top. Lead-generation companies running pay-per-meeting or pay-per-lead models buy 1,000-5,000 Outlook inboxes to drive raw send volume at the lowest possible cost per touch. Enterprise SDR teams at Series B+ SaaS companies buy 100-500 Google Workspace inboxes to support multi-region outbound while keeping deliverability comparable to their primary corporate domain.

What is the minimum bulk order?
Bulk pricing kicks in at 50 inboxes per order. Below 50, standard retail pricing applies. There is no annual commitment required to access bulk tiers, you just need to hit the unit count in a single purchase.
Do you offer wholesale or reseller pricing?
Yes. Buyers committing to 1,000+ inboxes per month qualify for our Wholesale tier with the lowest published per-inbox pricing. Resellers who want to white-label inboxes under their own brand should book a call to discuss volume commitments, payment terms and SLA.
What is the delivery time for 1,000+ inboxes?
Outlook orders of 1,000-7,100 inboxes deliver in 3-7 business days in staged batches. Google Workspace orders of 200-833 inboxes deliver in 5-10 business days due to Google verification throughput. Pre-warmed orders add 14-21 days of warmup before handoff.
What are the payment terms for large orders?
Standard bulk orders up to $25,000 are charged upfront via Stripe. Orders above $25,000 can be split 50/50 (deposit on order, balance on delivery) or invoiced via ACH/wire after a credit check. Enterprise orders above $100,000 are eligible for milestone-based billing tied to delivery tranches.
Do you offer NET 30 for agencies?
Yes. Agencies with at least three months of consistent monthly spend above $5,000 can apply for NET 30 terms. New agency accounts start on prepaid Stripe billing and transition to NET 30 once payment history is established.
Do you have a white-label or reseller program?
Yes. Our white-label program lets agencies and infrastructure providers resell Puzzle Inbox inboxes under their own brand, with custom domain naming, branded onboarding docs and a dedicated Slack channel for support escalations. Minimum commitment is 500 inboxes per month.
Can I use custom domains for bulk orders?
Yes. You can either supply your own domains or have us purchase domains on your behalf at cost plus a $1 per domain handling fee. Custom domain orders typically use 2-3 inboxes per domain to balance deliverability and per-domain cost.
What is the bulk replacement policy?
Any inbox that gets suspended within 14 days of delivery due to provider issues unrelated to your sending behavior is replaced free of charge. For bulk orders we batch replacements weekly so you receive a single replacement tranche rather than ad-hoc inboxes.
How do I scale past 5,000 inboxes?
Self-serve maxes out at 833 GWS Standard, 555 GWS Warm, 7,100 Outlook Standard or 5,000 Outlook Warm per order. Beyond those thresholds we book a scoping call to plan staged delivery, domain procurement and warmup pacing. There is no hard ceiling on total volume.
What are the discount thresholds (50/100/500/1000)?
Discount tiers are Starter Bulk at 50-99 inboxes, Growth Bulk at 100-499, Scale Bulk at 500-999 and Wholesale at 1,000+. Each tier reduces the per-inbox price by roughly 10-15% versus the tier below, with Wholesale offering the deepest cut.
Do you offer annual vs monthly billing for bulk?
Bulk orders are billed per order rather than as a subscription, so you control cadence. Buyers who commit to a 12-month volume target receive an additional 5-10% discount on top of the volume tier, billed monthly with an annual true-up at month 12.
