Separate, authenticated sending domains and warmed-up mailboxes, so your outreach can reach inboxes without putting your main domain at risk.
Cold outreach often fails before anyone reads it, because new domains and mailboxes land in spam. Sending from your main domain puts its reputation at risk too. Cold Email Infrastructure Setup builds separate sending domains and mailboxes in your own accounts. We authenticate every domain, connect your sending tool, switch on warm-up and test inbox placement before you send.

Cold Email Infrastructure Setup is a one-time service that builds the sending side of your outreach. We set up to 3 separate domains and 9 mailboxes in your own accounts. We add SPF, DKIM and DMARC, connect one sending tool, start warm-up and test inbox placement.
Many outreach projects look like they do not work, when the real problem is the sending setup. Missing DNS records, cold mailboxes and no warm-up send messages to spam. Fixing that yourself means hours of provider guides and trial and error. This service does the setup once, properly, in accounts you own. Your main domain stays out of it, so staff and customer email are protected. You get tested mailboxes, a sending-limit plan and a checklist for opt-outs. Results still depend on your list, your copy and how you send.
We register up to 3 separate sending domains in your registrar account. Each one redirects to your website, so outreach runs away from the domain your staff and customers use.
Every domain gets SPF, DKIM and DMARC records, with a DMARC monitoring address and a custom tracking domain. Mailbox providers can then check that your messages are genuine.
Warm-up is switched on in your sending tool, and a sending-limit plan sets a careful ramp. It caps each mailbox at no more than 30 emails a day.
We run an inbox-placement seed test and a blacklist check on every mailbox before handover. Anything that fails is fixed while we still have access.
Your portal lists these the moment you order. Delivery starts the working day after everything is in and your access is checked.
| Option | Delivery time | Price |
|---|---|---|
| Standard | 5–15 working days | $975 |
Before you start: Before work starts, note your recent open, bounce and reply rates and whether outreach was sent from your main domain.
These are things to track, not promised results. Outcomes depend on your data, your team and your market.
The setup itself has no ongoing fee from us. You pay the providers directly for domain renewals, monthly mailbox licenses and your sending tool plan. Any separate warm-up tool you choose is also yours to pay. Warm-up then runs for two to three weeks on your tool before full sending.
Ask about running costsAdd a note at checkout if you need something specific. If it fits within the Scope Card it is simply included. If it goes beyond it, you get a written Change Quote within two working days, and that work starts only once you accept it, with its time added to your delivery date.
Request a custom versionThis is a one-time setup, so there is no maintenance plan. The domains, mailboxes and settings live in your accounts and keep working as long as you renew them. Stick to the sending-limit plan and keep an eye on the DMARC reports. If you later want AI to write and send the outreach, AI SDR Agent and AI Outreach Sequencer build on this setup.
| Do it yourself | Hire a traditional agency | Upmark Labs | |
|---|---|---|---|
| Setup | You work through DNS records, mailbox settings and warm-up guides yourself | Often bundled into a larger outreach retainer | A fixed scope of 3 domains and 9 mailboxes, set up and tested |
| Ownership | Yours, if you set it up in your own accounts | Domains and mailboxes sometimes sit in the agency's accounts | Everything is created in accounts you own and control |
| Testing | Easy to skip until replies stop coming | Varies by provider | Inbox-placement and blacklist checks on every mailbox before handover |
| Main domain | Tempting to send from it to save time | Depends on the approach | Kept separate, so outreach does not touch its reputation |
Because spam complaints and bounces hurt the domain they come from. If outreach goes from your main domain, invoices, support replies and staff email can start landing in spam too. Separate sending domains keep that risk away from the domain your business depends on. Each one redirects to your website, so prospects who check it still find you.
Usually after two to three weeks of warm-up. We switch warm-up on during the setup, and it then runs on your sending tool while the mailboxes build a sending history. The sending-limit plan shows how to ramp up, with no more than 30 emails per mailbox per day. Going faster than that raises the chance of landing in spam.
No. Nobody can promise inbox placement, replies or meetings, because mailbox providers decide what to filter. What the setup does is remove the common technical reasons outreach lands in spam. Every domain is authenticated and every mailbox is tested before handover. Your list quality, your copy and how fast you send still make a big difference.
One sending tool from Instantly, Smartlead, lemlist, Apollo or HubSpot sequences, with mailboxes on Google Workspace or Microsoft 365. We work in your registrar or DNS host, such as Cloudflare, GoDaddy or Namecheap. A second sending tool is not included. Add a note at checkout and we will quote one through a Change Quote.
It covers the basics of CAN-SPAM in the US and GDPR and PECR in the UK and EU. That includes opt-out handling, sender identification and the questions to check before you email a contact. It helps you prepare and is not legal advice. For your own situation, especially when emailing people in Europe, check with a qualified adviser.
No, that is outside this setup. Repairing a blacklisted main domain is separate work with its own steps and timing. We can keep new outreach away from it with fresh sending domains, which gives your main domain a chance to recover. If you need help with the repair, add a note at checkout for a Change Quote.
You keep everything, and you get 14 days of post-launch support. The domains, mailboxes, DNS records and tool connections all sit in your accounts. During support you can ask about warm-up progress, test results or the sending-limit plan. After that, you renew the domains and licenses with the providers, and you can remove our access at any time.
Order Cold Email Infrastructure Setup for separate domains, authenticated mailboxes and tested warm-up, all in accounts you own.
