Inframail flat rate pricing seems too good. What is the catch?

I have been looking at inframail.io and their unlimited inbox model is tempting. Pay one flat fee and get as many inboxes as you want.
For someone running an agency with 100+ inboxes, the math looks incredible compared to per-inbox pricing. But it seems too good to be true.
Questions for anyone who has used Inframail: What kind of infrastructure do they use? Is it Google Workspace, Outlook, or custom SMTP? How is the deliverability? Does unlimited actually mean unlimited or are there hidden limits?
My concern is that unlimited flat-rate models incentivize the provider to cut corners on infrastructure to maintain margins. If they are using cheap SMTP rather than Google Workspace, the deliverability will suffer.
Currently on PuzzleInbox and deliverability is great, but the per-inbox cost adds up at scale. Would love to hear real experiences from Inframail users.

tried inframail for a month. the inboxes use custom SMTP, not Google Workspace or Outlook. deliverability was noticeably worse than my regular GWS inboxes. you get what you pay for

unlimited anything in email should be a red flag tbh. if it's too cheap the provider has to cut corners somewhere — either infrastructure quality, support, or deliverability

I manage 100+ inboxes for clients. tried inframail for a subset of them. reply rates were significantly lower than my Google Workspace inboxes on the same campaigns with the same copy. switched back within 3 weeks

the math on flat rate only works if the inboxes actually deliver. a $5 inbox that goes to spam is infinitely more expensive than a $4.50 GWS inbox that lands in the primary tab

honest question — has anyone had a GOOD experience with inframail? all i see is negative reviews but maybe there's selection bias in this sub

I used it for 2 months. Low volume sending (under 50/day total) was fine. The problems start when you scale up. At higher volumes the custom SMTP infrastructure just can't compete with Google Workspace deliverability.

custom SMTP will always struggle against native Google/Outlook infrastructure. Gmail trusts its own servers more than random SMTP IPs. this isn't even controversial, it's just how email works
