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

Mailforge is cheaper per domain. But the cost that matters is cost per booked meeting. Slicey's isolation means your emails actually reach the primary inbox. More inbox placement, more replies, more pipeline. The extra $20/domain pays for itself on the first deal you close.
