Why Project Inbox
Everything your cold email needs, done for you
We handle the technical setup that kills deliverability so your team can focus on writing great campaigns and booking meetings.
SPF, DKIM and DMARC
Every authentication record is configured correctly for you, so mailbox providers trust your domains from day one.
Automated inbox warm-up
We initiate warm-up as soon as your inboxes are ready, building sender reputation before your first campaign goes out.
Bulk domain setup
Buy domains in a few clicks with our in-platform guide, or bring your own. We connect and configure them all.
Scale in minutes
Order 10 or 1,000 inboxes and connect them to your sending platform. Scaling volume no longer means weeks of manual work.

About Project Inbox
Built by cold emailers, for cold emailers
We started Project Inbox because setting up deliverable infrastructure was eating whole weeks of every campaign. Buying domains, wiring DNS, getting SPF, DKIM and DMARC exactly right, then waiting out warm-up before a single email could send. So we turned all of it into a service. Today we run inbox infrastructure for agencies, recruiters and SDR teams who need to scale outreach without babysitting DNS records. Every inbox is Microsoft powered, authenticated and warmed, delivered in a day or two and priced from just $2.50.
Fully managed setup
24 to 48 hour delivery

Loved by outreach teams
"Getting started was effortless. We had authenticated inboxes ready in under two days and our open tracking looked healthy from the first send."
"We tried building infrastructure in house and burned domains fast. Project Inbox handles the SPF, DKIM and DMARC side so our SDRs just focus on booking calls."
"Everything lives in one place now. We scaled from a handful of inboxes to dozens without the usual deliverability drop off. Way less back and forth."

FAQ
Answers before you order
What exactly is included when I order an inbox?
Each inbox arrives fully set up: a Microsoft powered mailbox, domain connection, complete SPF, DKIM and DMARC configuration and automated warm-up. It is then linked to your cold email platform so you can start sending straight away.
How do SPF, DKIM and DMARC improve deliverability?
These records prove to mailbox providers that your email is authentic and authorised to send from your domain. Configured correctly, they build sender trust, reduce spam filtering and help your outreach reach the primary inbox instead of the junk folder.
How long until my inboxes are ready to use?
Most orders are delivered within 24 to 48 hours once onboarding is complete. Timelines depend on you providing access and completing setup steps promptly. We recommend allowing time for warm-up before launching high volume campaigns.
Which cold email platforms are compatible?
Our inboxes connect with the major sending tools including Instantly, Smartlead.ai, Reachinbox, Saleshandy and Woodpecker. If you use a different platform for your outreach, reach out and we will confirm compatibility.
Do I need to buy my own domains first?
You can bring existing domains or buy new ones. If you need domains, our platform includes a step by step guide to bulk purchase the right ones in a few clicks. We then handle the connection and configuration for you.
Can I cancel my subscription anytime?
Yes. You can cancel any time from the subscription management section of your account. Cancellation takes effect immediately and your access continues through the end of the current billing cycle, with auto-renewal switched off.
