Platform Coverage

Inframail is Outlook-only. Good for Microsoft-heavy prospect bases. Limiting for mixed ICP.

Maildoso is Google Workspace only. Good for Gmail-heavy prospects. Limiting for Microsoft-heavy ICP.

Neither provider offers both platforms — teams wanting diversification need a dual-platform alternative.

Cost Analysis

At 50 inboxes:

Inframail: $99-299/month flat + $750-1,250/month warmup = $850-1,550/month all-in
Maildoso: 50 × $3 = $150/month + $750-1,250 warmup = $900-1,400/month all-in

Total costs are comparable once warmup is factored in.

Deliverability

Inframail reply rate: 2-3% (Outlook-to-Outlook), 1.5-2% (Outlook-to-Gmail).

Maildoso reply rate: 1.5-3% on shared Google Workspace (variable).

Both have below-average deliverability vs pre-warmed alternatives.

Account Health

Both providers have higher account suspension rates than premium alternatives due to infrastructure patterns. Bulk provisioning and shared/related setups trigger platform anti-abuse systems.

When Inframail Wins

Large-scale Outlook-heavy cold email operations
Teams with technical bandwidth to manage many inboxes
Operators where unlimited flat pricing math works

When Maildoso Wins

Small operations under 20 Google Workspace inboxes
Gmail-heavy prospect targeting
Per-inbox pricing preference

Verdict: Both providers target the budget segment with structural trade-offs. Pre-warmed dual-platform providers like Puzzle Inbox deliver better deliverability at comparable all-in cost with Google AND Outlook from one source.
