Maildoso Pricing: What You Pay
Full breakdown of every Maildoso plan, mailbox type, and domain cost. Here is what you actually pay at scale and how it compares to InboxKit.
Bottom line
Maildoso offers the cheapest per-mailbox pricing in the infrastructure space. SMTP from $1.90/mailbox and Combo (SMTP + Google Workspace) from $2-$3/mailbox. Domains from $2 each.
The trade-off: no warmup, no verification, no inbox placement testing. You need SendKit or another tool for deliverability. For teams that want deliverability tools included, InboxKit at $2.50/mailbox is the better value.

How Maildoso Pricing Works
Maildoso uses per-mailbox pricing with two tiers. SMTP mailboxes run $1.90 to $2.50 per month. Combo mailboxes (SMTP plus Google Workspace) cost $2 to $3 per month.
Domains are available from $2 each. The pricing is the most competitive in the market for raw mailbox provisioning. No base fees, no tiers to navigate.
Just pick your mailbox type and scale.
Key takeaways
- SMTP: $1.90-$2.50/mailbox/mo
- Combo (SMTP+GW): $2-$3/mailbox/mo
- Domains: from $2/domain
- No base fees or tier requirements
Cost at Scale
At 50 SMTP mailboxes: $95-$125/mo. At 100: $190-$250/mo. At 200: $380-$500/mo.
Add domains at $2 each for initial setup. Compare to InboxKit at $2.50/mailbox: 50 mailboxes cost $125, 100 cost $250, 200 cost $500. The gap between Maildoso SMTP and InboxKit is $0 to $60 per month at 100 mailboxes.
But InboxKit includes warmup, verification, and placement testing that you would otherwise need from SendKit or another tool.
Key takeaways
- 100 SMTP mailboxes: $190-$250/mo
- 100 InboxKit mailboxes: $250/mo (with deliverability tools)
- Real cost gap is $0-$60/mo at 100 mailboxes when tools are factored in
All-inclusive from $99/mo
Dedicated IPs, warmup, validation, inbox testing, blacklist monitoring. No add-ons.
