Placement Tests

A placement test answers the only question that matters in deliverability: where does your mail actually land? Open rates and bounce logs are proxies. A placement test is a direct measurement.

How it works

When you run a test, EmailWarmer sends one email from your mailbox to a set of seed addresses — real inboxes we control across the major providers (Gmail, Microsoft, Yahoo, and others). Each seed reports back where the message arrived. A few minutes later you get:

• Per-provider placement — inbox, spam, or promotions, broken down by provider
• An overall inbox rate — the share of seeds where your mail hit the primary inbox

Because the seeds span providers, you'll often find your mail inboxes fine at Gmail but lands in spam at Microsoft (or vice versa). That granularity is the point — it tells you where to focus.

Running a test

1. Open the mailbox you want to test.
2. Start a placement test. The test email sends automatically from your connected mailbox — no copy-pasting or manual sending.
3. Wait for the seeds to report. Results appear per provider as they come in.

If you haven't connected a mailbox yet, start with the quickstart.

Reading the results

A single spam placement at one provider isn't a crisis. A pattern — the same provider flagging you across consecutive tests — is a signal worth acting on.

How often to test

Once a mailbox is warmed and stable, you can drop to a test every couple of weeks, plus an extra test before any significant campaign or after any change to your DNS records or sending setup.
