Inbox-warmup tools vs. ramping volume by hand

Inbox-warmup tools vs. ramping volume by hand
Everyone says: "Run a warmup tool — it auto-exchanges emails to build sender reputation."
Myth. Warmup networks send fake mail to fake inboxes that fish your message out of spam and reply with gibberish, and mailbox providers increasingly recognize the pattern. You're not building reputation; you're simulating it, and the simulation is getting detected. Real reputation comes from real recipients engaging — start at ten genuine sends a day and climb as replies come in. It's not a warmup you buy, it's one you earn slowly. The shortcut is the thing now getting flagged.
