Here's what happens next
Google Workspace, Outlook, prewarmed, SMTP, all under one roof. Place your order, fill a 3-minute form, and we build everything. You focus on campaigns. We handle the plumbing.
Nothing is shared. Every inbox runs on its own dedicated IP, in its own isolated workspace. No shared servers, no shared tenants, no cross-contamination from other senders. Your infrastructure is yours alone.
Bring your own domains or let us buy them for you, either way, we handle everything. SPF, DKIM, DMARC, forwarding, tracking, all configured end-to-end. You just tell us what you need.
We don't just set it up and disappear. Swap inboxes, update profiles, add seats, anything you need, anytime, at no extra cost. One Slack message and it's done.
Deliverability isn't set-and-forget. We actively monitor trends, adapt to policy changes, and tune your infrastructure daily. The result: consistent inbox placement that holds up campaign after campaign.
Zero risk - Bulletproof inboxes built for scale and reliability
Microsoft 365 enterprise inboxes based on Azure. Each domain includes 50 users.

Get the Answers You're Looking For
Yes to all. You can customize everything: profile pictures, passwords, forwarding rules, signatures - whatever you need. We'll help with the technical setup to ensure everything works properly.
After the initial month or two, your sending practices, nature of campaigns, level of personalization, and new regulation policies will influence your deliverability. We monitor and optimize continuously, but results also depend on your campaign quality.
Yes, we can buy domains for you at $15/domain. As standard, we only buy .com domains as they perform the best.
Absolutely. You get complete access to the inboxes and can easily log into them if you'd like to.
Yes, we provide ongoing monthly support to all of our clients. For clients with over 100 inboxes, we have a dedicated account manager and a private Slack channel for priority support.
Yes, we upload the accounts into your Smartlead/Instantly or any sending platform using OAuth, and we even turn on warmup for you.
Shared IPs from these providers are prone to blacklisting because they attract spammers and abusers. This means you're sharing servers with high-risk users, increasing the risk to your outbound emails. Our inboxes offer safer, dedicated infrastructure.
IP-based inbox providers share IPs among multiple users, increasing the risk of blacklisting. Our service provides dedicated, isolated infrastructure for each client.
We recommend a 3-week warmup period before you start sending cold emails.
Everything would get delivered in less than 72 hours.

We have a free replacement policy - if an inbox gets burned, we'll replace it at no cost (just cover domain costs if new domains are needed).
Everything you need: complete DFY inbox setup, technical configuration, domain management, custom tracking domains, warmup configuration, platform import, and ongoing support.
Yes, you can use your existing domains without any extra fees. Just make sure they aren't connected with any existing Google Workspace or Microsoft 365 account.
Yes, but be aware that previously used domains may have reputation issues or low deliverability which can carry over to your brand new infrastructure.
We recommend using secondary domains to protect your primary domain's reputation. This strategy helps mitigate risks associated with cold outreach.
Yes, you have full ownership of any domains purchased through us.
You can buy domain credits, 1 credit = 1 .com domain. Domain credits don't expire, and you can redeem them anytime.
We handle all aspects: configuring domains, SPF, DMARC, and DKIM records, custom domain tracking, and domain forwarding.
We support all domain providers, we don't discriminate.
No, these are not reseller inboxes. They're built specifically for you, giving you dedicated access and control with no shared infrastructure.
Yes, every single order comes with a dedicated IP and an individual tenant, so there is absolutely no sharing with other customers. Your sending reputation stays completely isolated, which means what other senders do can never impact your deliverability. This is one of the key reasons our inboxes consistently outperform shared infrastructure providers.
Yes, we take care of that for you, ensuring a smooth integration with your sending platform.
You get the full package: technical setup, inbox and user creation, account import, and ongoing management. Basically, we handle everything.
It depends on who you're targeting. If you're focusing on larger companies, 30-40% Outlook inboxes is ideal. For SMBs or startups, a lower percentage works fine.
A tenant is essentially the environment or workspace where your inboxes live. It's tied to an IP address, and its reputation directly affects your deliverability.
