Slicey vs Infraforge
How Slicey's isolated architecture compares to Infraforge's shared-panel bulk inboxes.
Infraforge makes it easy to spin up large numbers of Microsoft inboxes at competitive prices. But like most providers, they use shared Microsoft panels. Your domains sit alongside other customers' domains. If someone on your panel sends spam or gets flagged, your deliverability takes the hit. Slicey costs more per domain, but every domain is completely isolated with its own Microsoft account, credit card, proxy, and fingerprint.

The bottom line
Infraforge is cheaper per domain. But you're paying for shared infrastructure. If another customer on your panel gets burned, your deliverability drops too. With Slicey, your domains only depend on your own sending behavior. The price difference is small compared to the pipeline you lose when emails go to spam.
