KNOWLEDGE BASE
Cold Email Infrastructure FAQs
What is cold email infrastructure?
Cold email infrastructure is the technical foundation behind outreach campaigns. It includes domain setup, inbox provisioning, SPF, DKIM, DMARC alignment, sending limits, and reputation management to ensure consistent inbox placement.
Why not send from my main business domain?
Cold outreach carries risk. Using dedicated sending domains protects your primary business domain from blacklisting or reputation damage.
How many inboxes should I use per domain?
We recommend 2–3 inboxes per domain with controlled sending limits. Scaling is achieved through additional domains rather than overloading a single one.
How long does setup take?
Most setups are completed within 24–48 hours depending on DNS propagation and account provisioning.
Can I scale safely after setup?
Yes. Infrastructure is structured with scaling in mind. We implement domain segmentation and inbox distribution strategies to maintain long-term deliverability.
