Pricing
SMTP mailboxes from $1.80/month. Domains at $8/year first year ($12/year renewal). Google Workspace accounts also available at higher pricing.
Compare to:
- Mailforge: $2-3/inbox
- Hypertide: $1/inbox at scale
- Infraforge: $3-4/inbox with dedicated IPs
Maildoso wins on pure mailbox cost. Factor in domain costs when comparing.
The Shared IP Tradeoff
Maildoso uses shared IPs. Your deliverability depends partially on other users.
This means:
- More inbox-to-inbox variability
- Need to monitor and rotate underperformers
- Can't set and forget
Teams who monitor their inboxes get good results. Teams who don't monitor get frustrated.
Who Should Use Maildoso?
Good fit:
- Bootstrapped teams watching costs
- Testing cold email before bigger investment
- High-volume senders comfortable with rotation
Not ideal for:
- Teams who want to set and forget
- Anyone without inbox monitoring
- Agencies who can't afford deliverability issues
