Discover the Preferred Alternative to Mailscale - Inframail

Inframail is email infrastructure built for cold outreach. We give you unlimited Microsoft-backed inboxes on your own domains, with SPF, DKIM and DMARC configured automatically — so you can stand up a complete sending system in minutes instead of days.

Email infrastructure is everything behind your campaigns: the domains, mailboxes, authentication records (SPF/DKIM/DMARC) and sending reputation that decide whether your emails reach the inbox. Inframail sets up and manages all of it for you.

Infrastructure is the single biggest factor in deliverability. Properly configured domains and inboxes mean more emails land in the primary inbox, fewer get filtered to spam, and your sender reputation stays healthy — which directly means more replies and more clients.

Yes. You can buy domains directly inside Inframail and we connect and configure them automatically. You can also bring domains you already own.

No. Inboxes are included in your plan — you can create unlimited inboxes across your domains with no extra per-mailbox cost.

No. Inframail is flat-rate. You're never charged per email, so you can scale your sending volume without your bill scaling with it.

We recommend warming up new inboxes the same way you would on any platform. Inframail integrates cleanly with the warm-up and sending tools you already use.

Inframail is your infrastructure layer. You connect your inboxes to your preferred cold email sending tool (Instantly, Smartlead and similar) and send from there, while Inframail handles the inboxes, domains and authentication underneath.

Yes. Most customers drop their expensive per-seat Google Workspace and Outlook subscriptions once they're on Inframail, since you get unlimited inboxes for a flat fee.

Excellent. Because every inbox ships with proper SPF, DKIM and DMARC and runs on Microsoft-backed infrastructure, your emails are built to land in the inbox — and we provide real-time deliverability monitoring on top.

Instantly and Smartlead are sending tools — Inframail is the infrastructure they run on. We provide the domains and inboxes; they run the campaigns. They work together, not instead of each other.

Yes. Domains you purchase through Inframail are yours — if you unsubscribe, you keep ownership and can transfer them to any registrar you like.
