I will build your cold email infrastructure with spf dkim dmarc and deliverability
George O
About this gig
Most cold email campaigns fail because the infrastructure was never built to survive volume.
I build cold outbound systems the way infrastructure engineers do: domains and mailboxes configured correctly, ICP-specific offers instead of one generic pitch, and deliverability protected at every stage not bolted on after inboxes start landing in spam.
I work with founders, agencies, and B2B teams who want qualified sales meetings, not just "sent" email counts.
What I handle:
- Domain and mailbox setup
- SPF, DKIM, DMARC configuration and inbox warmup
- ICP mapping and offer creation tailored messaging per segment, not a single generic template
- Lead list building (Apollo, targeted scraping where relevant)
- Data enrichment and verification (waterfall email verification, custom variables)
- Plain-text, spam-filter-conscious sequence copywriting (max 3-4 step sequences)
- Sending platform setup (Instantly or Smartlead)
- Launch and first-pass optimization based on real reply data
I don't guarantee results What I guarantee is a system built correctly from the infrastructure up, so the offer actually gets a fair test in front of the right people.

FAQ
Do you guarantee replies or meetings?
No — anyone guaranteeing specific reply/meeting numbers in cold outbound isn't being straight with you. I'll give you realistic benchmark ranges based on similar campaigns, but actual results depend on your offer, ICP, and market conditions.
Do I need to already have Apollo/Clay/Instantly?
Yes Very necessarily — I can recommend and set up tools, costs are covered by the client directly.
Why separate domains instead of using our main company domain?
Cold outbound carries deliverability risk. Using dedicated domains protects your primary domain's sender reputation if anything goes wrong during warmup or sending.
What if I already have some of this in place (e.g., I already have Apollo, or existing mailboxes)?
Packages can be adjusted — message me with what you already have and I'll scope accordingly.
Do you help once we're getting replies and want to scale?
Yes — once a system is proven, I build custom reply-handling tools (automated classification and routing of replies) as part of ongoing management. This is a retainer-based add-on for clients moving from setup into scale, not part of the one-time build.
