No long term lock in · Works with Microsoft 365 · Built for teams and agencies
Export to any platform in one click
Everything you need beyond cheaper inboxes — bring or buy domains, get DNS handled for you, keep domains isolated, connect your sequencer, and scale inboxes in bulk.
Every client gets a dedicated Microsoft 365 tenant. No shared infrastructure, no cross-contamination. Your deliverability stays yours.
Connect your domains and walk away. We auto-configure MX, SPF, DKIM, and DMARC across Cloudflare, GoDaddy, Porkbun, Namecheap, and Spaceship.
Export mailboxes directly to Instantly, SmartLead, Apollo, and 12+ other sequencers. No CSV files. No copy-paste. Just click and send.
Real-time blacklist monitoring, DNS health checks, and inbox placement tracking. Know exactly where you stand before your next campaign.
Manage domains, mailboxes, exports, and reputation — without switching between ten different tools.
Every domain you add means DNS records to configure, mailboxes to create, authentication to verify, and platforms to connect. Manually. Again and again.

"We were losing inboxes every week on shared providers. Since switching to MailMart, we haven't lost a single one. Our reply rates are up 40%."
Sarah Chen
Head of Outreach, GrowthPilot
"What used to take our team 8 hours every Monday morning now takes 15 minutes. We onboard new clients same-day instead of next-week."
Marcus Rivera
Operations Lead, ScaleReach
"The dedicated tenants sold us. But the 1-click export to Instantly changed how we operate. We scaled from 30 to 200 domains without adding headcount."

Most providers put hundreds of clients on shared Microsoft 365 tenants. When one client gets flagged, everyone suffers. MailMart provisions a dedicated tenant for each client — your reputation is completely isolated. Combined with automated DNS and 1-click export, you get enterprise infrastructure without the setup overhead.
Most clients go from sign-up to first export in under 30 minutes. Domain verification, DNS configuration, mailbox creation, and warmup initiation all happen automatically once you connect your domains.
We support 1-click export to Instantly, SmartLead, Apollo, Saleshandy, Woodpecker, Lemlist, QuickMail, Snov.io, Reply.io, and more. New integrations are added regularly based on customer requests.
We have direct API integrations with Cloudflare, GoDaddy, Porkbun, Namecheap, and Spaceship for fully automated DNS setup. For other registrars, we provide guided manual setup with copy-paste instructions.
Yes. We handle full migration with zero downtime. Your domains move to dedicated tenants, DNS records are updated automatically, and your existing sending reputation carries over.
No contracts, no lock-in. Pay monthly based on your usage. Scale up or down anytime. If you're not happy, you can leave at any time with full ownership of your domains and data.
Join 100+ agencies who switched to dedicated tenants. Set up your first domains in under 30 minutes.
