Why self-managed Google Workspace fails
Most teams get the account right and get the configuration wrong. Mailflo closes every gap.
Sending cold email from a zero-reputation Google Workspace inbox triggers Gmail's filters immediately. Without structured warmup, your account gets rate-limited or suspended before it ever reaches primary.
Google enforces per-inbox daily sending limits. Teams that push volume too hard from too few inboxes see their sender reputation tank — and recovery takes weeks of reduced sending.
Google's SPF and DKIM configuration is specific to Workspace. One wrong record — a missing include, a broken selector — and Gmail rejects authentication on every outbound email.
Without monitoring Postmaster Tools, teams have no idea their domain reputation is declining until open rates collapse. By then, the damage requires weeks of rehabilitation to undo.
Done-for-you Google Workspace infrastructure
Six services that cover the complete Google Workspace cold email stack — from provisioning to ongoing Postmaster monitoring.
Real Google Workspace mailboxes provisioned under your billing account — with profile photos, signatures, and correct sending configurations — in under 30 minutes.
Full Google-specific authentication stack configured automatically: Google's SPF include, a DKIM selector per domain, and a DMARC policy that meets Gmail's bulk sender requirements.
AI-driven warmup using a network of real Google and Microsoft inboxes. Volume ramps over 14–21 days, building the sender trust Gmail needs before you start cold outreach.
Sending volume is distributed across all your Google Workspace mailboxes automatically, based on real-time health scores — keeping each inbox under safe daily limits at any scale.
Continuous monitoring of your Google Postmaster data — domain reputation, spam rate, authentication pass rate, and IP score — with instant alerts when any signal drops.
Blacklist checks across 50+ providers, inbox placement tests, weekly performance reports, and same-day removal requests if any domain gets flagged.

Inbox rotation keeps every mailbox under safe limits. Postmaster monitoring catches any signal drop before it affects your campaigns.
