Infrastructure Differences
MailDeck: Dedicated Microsoft 365 Tenants
MailDeck provisions a dedicated Microsoft 365 tenant for each domain. Each tenant includes 100 Outlook inboxes with automated DNS configuration (SPF, DKIM, DMARC). Your emails send through Microsoft's servers with Microsoft's 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 details, see our SPF, DKIM, DMARC setup guide.
ScaledMail: Managed Multi-Provider Infrastructure
ScaledMail manages Google Workspace, Microsoft 365, and SMTP inboxes with isolated tenants per customer. They offer white-glove setup with expert configuration and dedicated Slack support.
This matters if you prefer hands-on managed service, need dedicated support channels, or want pre-aged domains included.
Where MailDeck Falls Short
To give you an honest comparison, here's where ScaledMail has advantages:
White-glove setup. ScaledMail offers expert configuration with dedicated support. MailDeck handles setup automatically in 48 hours without hands-on assistance.
