Authenticated domains and warmed mailboxes still need to be connected into a sending platform that can rotate sends across them, track engagement without triggering spam filters, and handle unsubscribes automatically. This is the final step before a campaign goes live.
Platform Choice: Smartlead or Instantly
We connect infrastructure into either Smartlead or Instantly depending on your volume and reporting needs. Both platforms support unlimited mailbox connections and built-in warmup tracking, but they differ in automation depth and pricing at scale, and we recommend the right one for your specific send volume during the infrastructure build rather than defaulting to whichever tool is trendiest.
What Gets Configured
- All mailboxes connected and rotation logic set so no single mailbox exceeds its daily send cap
- Open and click tracking configured carefully, since aggressive tracking pixels are themselves a spam trigger if implemented wrong
- Unsubscribe handling automated and legally compliant, removing contacts across every connected mailbox instantly
- Reply detection configured so positive replies route to a shared inbox or CRM instead of getting buried
- Sending schedule and daily volume caps locked in per mailbox to match the warmup and reputation status of each domain
Why This Step Is Not Just a Formality
A poorly configured platform integration can undo weeks of careful domain and mailbox work in days. Tracking links that are too aggressive, rotation logic that overloads one mailbox, or missing unsubscribe automation all create the exact spam signals that a clean infrastructure build was designed to avoid.
Handoff
Once platform integration is complete and verified, you receive full login access, a rotation and volume summary for every mailbox, and a monitoring dashboard so you can see placement and reputation health at any time, not just when we report it to you.
