Meet the #1 Maildoso Alternative
Get real Google, Microsoft, and Azure mailboxes on US IPs — not SMTP combos. A powerful, monitored alternative to Maildoso, with Microsoft 365 support Maildoso lacks.
How does Maildoso compare with InboxKit?
Why choose InboxKit over Maildoso?
See why 3,000+ companies and agencies choose InboxKit over Maildoso for their cold outreach infrastructure.
Real accounts, plus Microsoft 365
Maildoso's cheapest mailboxes are SMTP — its own infrastructure, not real Google or Microsoft accounts — and it offers no Microsoft 365 at any tier. InboxKit provisions real Google, Microsoft 365, and Azure accounts.
- Real Google Workspace + Microsoft 365 + Azure
- Microsoft 365 coverage Maildoso doesn't offer
- Full provider admin access per domain

Test placement whenever you want
Maildoso runs scheduled placement tests every 3 days on SMTP mailboxes. InboxKit gives you unlimited, on-demand inbox placement testing across Gmail, Outlook, and Yahoo on every plan.
- Unlimited on-demand placement testing
- Inbox, spam, and promotions breakdown
- 95% guaranteed inbox placement rate

Always-on InfraGuard monitoring
Maildoso offers domain health and 14-day self-healing recovery. InboxKit's InfraGuard adds blacklist checks every 6 hours, DNS change detection, and bounce tracking across your whole infrastructure.
- Blacklist checks every 6 hours
- DNS watchdog and bounce tracking
- Real-time alerts across all mailboxes

Don't take our word for it. Take theirs.

Burned through 9 domains in 6 weeks with our old setup. Same domains have been running fine on InboxKit since March.

Jayson DeMers

The unified inbox thing sounded like a gimmick until I realized my SDRs were missing replies across 30 different accounts.

Walter Winn
Anevo Marketing
Our agency manages 40 client accounts now. Would have been impossible before this.

Atishay Jain
Eagle Info Services
Our ops guy used to manually configure DNS for every mailbox. Now he's actually doing ops work instead.

Dimitar Petkov
Leadhaste
My reply rate jumped from 2% to 11% and I literally changed nothing except moving to InboxKit infrastructure.

Benjamin Douablin
Fullenrich
Went from sending 800 emails a day to 12,000. Deliverability got better somehow. Still don't fully understand it.

Jesse Oulette
Leadmagic
Finally stopped waking up to suspended Google accounts. It's been 6 months now and everything is still clean.

Abbas Somji
The Playbook Agency
Consolidated our entire cold email stack into one dashboard. Saved us 6 hours a week just in context switching.

I used to spend every Monday morning setting up new domains because the old ones kept dying. Haven't done that in months.
