No.

“$105k MRR, but it's mostly resold Google and Microsoft inboxes at ~$3 each. Mailforge, Zapmail and a dozen others sell the same thing.”

01/The verdict

Upscale B2B is a done-for-you outbound agency that runs email, calling and LinkedIn campaigns. Its sister brand Warm Inboxes sells cheap pre-warmed Google, Microsoft and Azure inboxes. Both are paid for by B2B companies and cold email agencies.

Most of the revenue looks like it comes from Warm Inboxes: 372 subscriptions at about $280 each, built on per-inbox seats priced at $2 to $3.50 for fresh and $8 for pre-warmed. That is commodity cold email infrastructure in a market with at least 10 well-funded rivals. A competitor's review says the seats come through the cheap reseller channel, so the supply isn't exclusive either. The only real friction is a stock of warmed domains and inboxes plus some agency know-how, and a newcomer with cash can build both in 4 to 8 weeks.

Infrastructure at scale

Shallow

~2 mo to cross

It sells pre-warmed Google, M365 and Azure inboxes with same-day delivery. That means holding a stock of domains and mailboxes that have already been warmed for weeks. The Azure tenant setup it markets as 'officially licensed' takes some know-how.

To cross it: Buy domains and reseller seats in bulk, then run them through a warmup pool for 4 to 6 weeks before launch.

Switching costs

Shallow

~1 mo to cross

Customers plug dozens to hundreds of inboxes into Instantly or Smartlead, and agency clients run campaigns that are already live. Moving means re-provisioning and re-warming, which costs them a few weeks of sending capacity.

To cross it: Offer free migration plus pre-warmed replacement inboxes, so the customer never has a gap in sending.

Real-world operations

Shallow

~3 mo to cross

The Upscale B2B side delivers through people running pilot campaigns across email, calling and LinkedIn. It claims about 200 clients, and some retention likely comes from service relationships.

To cross it: Hire SDR and copywriting contractors and offer the same free pilot or pay-per-meeting deal.

03/The gap

Easy to copy

  • The inbox provisioning dashboard and automatic DNS setup, which are a standard feature set across Zapmail, InboxKit and Mailforge
  • Cheap Google and Microsoft seats bought through the same reseller channel any competitor can use
  • The 'free pilot before you commit' agency offer, which rivals like Growth Engine X already run
  • Content and comparison-page SEO on a domain with a rating of only 25

How you'd go after it

  • Undercut on price: offer prices at or below $2 an inbox, or bundle free warmup, which Aerosend already does with 30 free inboxes for 30 days
  • Compete on deliverability quality: sell US-origin or dedicated-IP inboxes against claims that Warm Inboxes uses India-origin reseller seats
  • Go after Upscale's agency clients with pay-per-meeting pricing in one vertical, such as SaaS or dropshipping brands
  • Sell to agencies through Instantly and Smartlead partner listings and affiliate programs, where infrastructure buyers already shop

04/Build against it?

Only with an edge

The demand and revenue are real, but the market is a price war on commodity inboxes, and Google and Microsoft could crack down on it. Only enter with an edge on deliverability (your own IPs or tenants with proof of inbox placement) or an existing audience of agencies.
