email-infra-instantly-setuplisted

Set up and connect sending inboxes in Instantly (infrastructure side). Use for connecting Google, Microsoft and custom-SMTP inboxes, warmup configuration, advanced deliverability settings, the required Unibox toggles (Save undelivered emails is off by default and gates what the reporting can see), and vendor-managed versus in-house setup. Triggers on Instantly setup, connect inboxes, Instantly warmup, advanced deliverability, Unibox, Unibox settings, save undelivered emails, show auto-replies, ScaledMail, IMAP SMTP host, provider matching. Do NOT use for writing sequences or copy (use gt-cold-email) or buying domains (use the domain-research sub-skill).

Growth Today keeps **domain research and verification only** — hand off the domain-research output plus a brief, then **verify on delivery**.
