Email Warm-Up

Email warm-up gradually ramps a new mailbox's send volume and engagement so inbox providers learn to trust it before any cold outreach starts.

What is email warm-up?

Email warm-up is the process of slowly building a fresh mailbox's sender reputation. Most warm-up tools auto-send and auto-reply between accounts in a network, simulating real conversation patterns — opens, replies, threading — over 2–4 weeks before the mailbox is used for real outreach.

Why it matters

  • A brand-new mailbox sending 50 cold emails on day one lands 80% of them in spam
  • Reputation is per-mailbox and per-domain; both have to be warmed
  • Recovery from a cold-start mistake takes longer than doing warm-up properly the first time

A safe warm-up pattern

  • Authenticate domain (SPF, DKIM, DMARC) before any send
  • Start at 5–10 sends/day, ramp 5–10/day until you hit your target volume
  • Keep ramping engagement signals (replies, marks-as-not-spam) throughout
  • Don't stop warm-up the day you start outbound — keep a baseline of warm-up traffic running

How TexAu helps

Pair warm-up infrastructure with a TexAu-fed sequencer so cold outreach only starts once warm-up signals say the mailbox is ready, and so volume per mailbox stays inside safe ramp limits.
