Introduction

EmailWarmer is an email deliverability platform built around three jobs:

1. Warm up your mailboxes. Automated, human-like warmup conversations between real mailboxes build the sender reputation that keeps your mail out of spam. Volume ramps gradually, sends follow your working hours, and recipients open, reply to, and rescue your mail from the spam folder.
2. Measure where you land. Inbox placement tests show whether your emails hit the inbox, the spam folder, or promotions — before your real campaigns find out the hard way.
3. Watch your foundations. DNS audits (SPF, DKIM, DMARC, MX, rDNS), blacklist monitoring across major RBLs, and per-mailbox reputation scoring surface problems while they're still cheap to fix.

How warmup works in one paragraph

When you connect a mailbox and enable warmup, it joins the warmup network. Each day the scheduler plans a ramped number of conversations for it — starting at 5 emails/day and climbing to your target over ~30 days. Your mailbox sends natural-looking messages to other mailboxes in the network; they open them, mark them not-spam if needed, and often reply. Your mailbox does the same for others. Every interaction is a positive engagement signal recorded by Gmail, Microsoft, Zoho, and whoever else receives your mail.

Where to start

• Quickstart — connect your first mailbox and start warming in about five minutes.
• Provider guides: Google Workspace, Microsoft 365, Zoho Mail, or any SMTP/IMAP server.
