# How Warmerly works: the email warmup process end to end

URL: https://warmerly.com/how-it-works

> A complete walkthrough of how Warmerly warms a mailbox: from OAuth connection, ramp schedule, peer pairing, send/reply/recover loops, daily authentication checks, and reputation scoring.

Seven phases, all automated. From the moment you connect a mailbox to the day you ship your first campaign, here is exactly what Warmerly does.

## Phase 01: Connect your mailbox (60 seconds)

OAuth into Google Workspace, gmail.com, Microsoft 365, or Outlook.com. We request only the scopes needed to send and receive warmup mail (gmail.modify or Mail.ReadWrite + Mail.Send). No password is ever entered, stored, or transmitted. You can disconnect at any time, which immediately revokes every token we hold.

## Phase 02: Profile your domain and existing reputation (~2 minutes)

Before sending anything, Warmerly reads your DNS to determine domain age, SPF chain, DKIM selectors, DMARC policy, and MTA-STS state. We probe the mailbox for prior send volume, IMAP folder structure, and existing spam-folder population. The output is a baseline health score and a recommended ramp curve tuned to your specific starting point.

## Phase 03: Pick a ramp schedule (30 seconds)

Choose Conservative, Balanced, or Aggressive, or build your own. Conservative starts at 4 warmup sends per day and adds 2 per day, capping around 40. Balanced starts at 6 and adds 3, capping around 60. Aggressive starts at 10 and adds 5, capping around 100. You can change at any time and Warmerly auto-throttles back if your health score drops.

## Phase 04: Peer pairing kicks in (continuous)

Warmerly's pairing service decides who your mailbox should talk to today. Brand new mailboxes are matched mostly with aged, healthy peers. As your reputation grows, your mix shifts toward newer correspondents and cross-provider sends. You never warm against your own mailboxes.

## Phase 05: The send / reply / recover loop (all day, jittered)

Throughout your recipient's working day, with realistic jitter, Warmerly sends a small batch of warmup messages from your mailbox to its current peer set. Recipients open, mark important, star, reply with a contextual quoted-reply, and (critically) rescue from spam if the message landed there. Every action is performed by a real OAuth-connected mailbox, never simulated headers.

## Phase 06: Daily authentication and placement checks (every 24 hours)

At a randomised time each day, Warmerly re-verifies SPF, DKIM, DMARC, MX, and TLS-RPT for every connected mailbox. We also send tracked seeds to a panel of provider accounts to measure inbox placement: Gmail primary, promotions, updates, social, or spam.

## Phase 07: You read the dashboard and ship campaigns

Once health is consistently above 80 with stable inbox placement, you are ready to run real outbound. Warmerly keeps warming in the background while your campaigns run, so reputation does not decay during quiet periods.

Recommended green-light threshold: 80+ for 5 consecutive days.
