Feature Comparison
Infrastructure Approach
Inframail uses Microsoft-backed infrastructure with automatic SPF, DKIM, and DMARC setup. It's shared among Inframail users but still better than pure shared IPs.
Mailreef provides dedicated servers at entry-level pricing. You get more isolation than shared infrastructure without premium pricing.
Cost Comparison
Inframail's flat-rate model means your per-inbox cost drops as you scale. At 100+ inboxes, you're paying significantly less per inbox.
Mailreef at $3-4/inbox is straightforward per-inbox pricing. At smaller scale, the total cost may be comparable, but dedicated servers provide better isolation.
