VS
Which one fits your sending
Choose Mailboundry if
- A dedicated IP from $1.30, or a vetted and monitored pool from $0.80, instead of rotation across pools you cannot see
- No 15-a-day ceiling imposed by the mailbox provider
- Buy the exact mailbox count you need, monthly, with no plan blocks
Choose Maildoso if
- You need the lowest sticker price per inbox and will commit quarterly to get it
- A 15-emails-a-day ceiling per mailbox suits how you spread volume
- You want self-healing mailboxes and IP rotation handled for you
Both give you
- SMTP mailboxes built for outbound rather than office email
- Automated DNS and authentication
- Domains bought in-app
- API access
- Deliverability and reputation monitoring

100 mailboxes, both ways
A hundred mailboxes is where per-mailbox pricing stops being an abstraction. Domains are extra on both sides.
100 mailboxes at $1.50 on annual billing, dedicated IP each, domains $8–$14 a year, and no per-mailbox daily ceiling.
100 mailboxes = a 70 block ($158) + a 30 block ($75), shared IPs, 15 emails a day each, plus $12 per domain a year.
Three reasons that decide it
The cheap rate has a quarter attached
The headline price needs 400 mailboxes paid quarterly. At 100, costs are within a few dollars, and Mailboundry includes the IP.
Caps decide your real capacity
15 a day caps 100 mailboxes at 1,500 sends. Mailboundry limits follow your plan and warmup.
Rotation is not isolation
Shared rotation spreads risk but doesn’t remove it. A dedicated IP makes the data yours.
