Slicey vs Mailforge
How Slicey's managed, isolated inboxes compare to Mailforge's self-service shared infrastructure.
Mailforge offers affordable, self-service inbox infrastructure with automated setup. It's popular with high-volume senders who want to keep costs down. But Mailforge uses shared infrastructure, so your domains share resources with other customers. With Slicey, every domain gets its own isolated Microsoft account, and our team handles the setup for you.

The bottom line
