The most time-consuming part of launching a new cold email campaign used to be the infrastructure setup. Buying 50 domains, setting up DNS records on each, creating Google Workspace or Microsoft 365 accounts, configuring forwarding, and pushing the inboxes into a sequencer would eat three to five working days for any new client. Resellers killed that timeline. A properly run reseller will spin up 50 inboxes, fully configured, in under a minute of operator time.
This guide covers the exact reseller stack we use at Borks, what a good reseller actually sets up for you, the total cost, and the mistakes to avoid when picking a provider.
What a cold email inbox reseller does
A reseller is a company that buys Google Workspace or Microsoft 365 accounts at wholesale rates, provisions them in bulk, configures the sending infrastructure, and resells them to outbound operators at a markup. Because the reseller handles all the setup, the operator effectively gets a fully provisioned inbox with zero manual work.
The work a good reseller handles for you
- Domain purchase and forwarding. You supply the root domain pattern, the reseller buys the variants.
- DNS records. SPF, DKIM, DMARC, MX records all configured correctly.
- Inbox creation. Google Workspace or Microsoft 365 accounts with Gmail or Outlook access.
- Forwarding setup. Replies forward to a central inbox of your choice.
- Integration with sequencer. Direct push into Smartlead, Instantly, or any modern sequencer that supports CSV or API ingest.
The work you should still do yourself
- 14-day warm-up before the first campaign.
- Campaign copy and sequence design.
- Reply management and triage.
- Campaign-level reporting.
The reseller stack we run
We have tested 15 plus resellers over four years. Most are between fine and dangerously bad. Two have proven reliable enough to run at scale across client campaigns. Both are named below.
Primary: verified direct-from-Google resellers
The best resellers source their Google Workspace inventory directly from a named Google representative, not from third-party markets. This guarantees US or European IP addresses on the accounts, which is a core deliverability requirement. Third-party markets often return Indian or Pakistani IPs, which have worse sender reputation and measurably lower inbox placement.
Backup: certified Microsoft partners
Microsoft 365 accounts through a certified Microsoft Solutions Partner. Slightly more expensive per inbox than Google, but useful as a diversification layer when Google tightens enforcement on a specific pattern. We rotate Microsoft inboxes into the pool at a 20 to 30 percent mix.
The pricing benchmark
Google public price
~$7.20 per inbox / mo
Reseller price
$2.60 to $3.80 per inbox / mo
Setup time per 50 inboxes
< 60 seconds of operator time
Total cost per 50 inboxes / mo
~$130 to $190
Providers to avoid and why
The reseller market is full of low-quality providers. Three patterns to avoid.
Pattern 1: geographic arbitrage from lower-income markets
Some resellers buy Google accounts at regional pricing from India, Pakistan, Vietnam, or similar markets where Google charges less. The inboxes work, but the sending IPs trace back to those regions and carry significantly worse deliverability than US or EU accounts. Reply rates on these inboxes run 40 to 60 percent of the equivalent on a US IP.
Pattern 2: aged accounts of unknown origin
A handful of providers sell aged accounts with a history. Sometimes these work. More often they carry hidden issues: previous spam activity, blacklisted IPs, or policy flags that reduce sending capacity. Avoid any reseller that cannot explain exactly how the accounts were provisioned.
Pattern 3: opaque support and slow response
Deliverability issues happen. What matters is how fast the reseller responds. A 4-hour turnaround on an inbox issue is acceptable. A 48-hour turnaround breaks campaigns. Test support responsiveness before signing on for volume.
The setup flow in practice
Here is what a proper reseller onboarding looks like end to end.
- Send the reseller your desired root domain pattern (e.g., getacme.co, tryacme.com, acmehq.co).
- The reseller purchases 50 domains matching the pattern from Porkbun or similar registrar.
- DNS records get configured automatically on domain provisioning.
- Google Workspace or Microsoft accounts are created on each domain, typically two to three inboxes per domain.
- Forwarding and sequencer integration is configured.
- You get a spreadsheet back with all 50 inboxes, passwords, and a ready-to-push integration link.
Total elapsed time from request to ready inboxes is typically 24 to 72 hours. Total operator time on your side is the five minutes you spend sending the request.
The one thing the reseller cannot do for you
Warm-up. Even the best-provisioned inbox with perfect DNS is still a zero-reputation sender. Gmail and Microsoft do not know you. The 14-day warm-up is mandatory regardless of where the inboxes came from. Any reseller that tells you their inboxes are "ready to send campaigns immediately" is lying. Warm-up is non-negotiable, and no provisioning shortcut fixes it.
Setting up 50 inboxes used to be the work that killed weekend after weekend. The reseller model turns it into a 24-hour turnaround for 130 to 190 dollars a month. Every operator running cold email at any scale should be using one. The only open question is which. The pattern above narrows the answer to a handful of competent providers in any given year.
