Infrastructure Differences

MailDeck: Dedicated Microsoft 365 Tenants

MailDeck provisions dedicated Microsoft 365 tenants, Google Workspace inboxes, Outlook tenants, and SMTP inboxes with automated DNS configuration (SPF, DKIM, DMARC). Your emails send through Microsoft's or Google's servers with their established sender reputation.

This matters most when your recipients are enterprise companies using Microsoft Exchange. Microsoft-to-Microsoft email receives higher trust from corporate spam filters. For DNS setup details, see our SPF, DKIM, DMARC setup guide.

Mailreef: Dedicated Servers with Dedicated IPs

Mailreef provides dedicated servers with dedicated IPs. They emphasize that "70% of Email Delivery Success Starts with Your Server." Their approach gives you control over your IP reputation from scratch.

This matters if you prefer building your own IP reputation or need the specific control that dedicated servers provide.

Where MailDeck Falls Short

To give you an honest comparison, here's where Mailreef has advantages:

Pre-warmed infrastructure. Mailreef offers pre-warmed mailboxes ready to send. MailDeck's Microsoft 365 tenants inherit Microsoft's reputation, but we still recommend 3-7 days of warm-up before full cold sending volume.

Dedicated IP control. Mailreef gives you dedicated IPs that you control and build reputation for. MailDeck uses Microsoft's shared IP infrastructure within your tenant.

Delivery consulting. Mailreef offers delivery consulting services as part of their premium positioning. MailDeck focuses on infrastructure provisioning.

Google Workspace focus. MailDeck offers both Microsoft 365 and Google Workspace, but our primary focus and strongest infrastructure is Microsoft 365. If you need equal emphasis on Google Workspace, evaluate Mailreef's offering.

Setup speed. MailDeck takes 48 hours to provision tenants. Mailreef's pre-warmed infrastructure may be ready faster.

Minimum purchase. MailDeck's minimum varies by product (starting from 1 inbox for SMTP or 1 tenant for Outlook). Mailreef's minimum may be lower depending on their custom pricing.

Where MailDeck Wins

Transparent pricing. MailDeck publishes all pricing on our website. No demo calls required. Pricing varies by product — from $0.40/inbox (SMTP) to $3.50/inbox (Google Workspace).

Dedicated infrastructure. Each MailDeck domain gets its own Microsoft 365 tenant. Your domains are fully isolated from other customers.

Enterprise deliverability. Microsoft 365 infrastructure has the highest trust with corporate mail servers. We maintain 98% inbox placement across 650K+ managed Outlook inboxes.

Simple scaling. MailDeck pricing is linear. Add domains to add capacity. No negotiation required. To calculate capacity needs, see our inbox calculator.
