# Free Email Inbox Placement & Spam Tester

> Free email inbox placement and spam tester. Test deliverability across Gmail, Microsoft 365, Yahoo, and Apple Mail with live seed inboxes before sending.

Authentication checks tell you whether your records are correct. They do not tell you whether Gmail put your message in the inbox. This sends one message to real seed accounts and reports placement per provider.

## Checks Performed
- Placement per provider — inbox, promotions, spam, or missing
- Authentication results as each provider actually evaluated them
- The raw headers of the received message
- Content signals that commonly push mail to promotions

## Sample Verification (Test message · seed run)
Four of five providers delivered to the inbox. The outlier is consistent with a young sending domain.

| Check | Verdict | Details |
| --- | --- | --- |
| Gmail | PASS | Inbox |
| Outlook / Microsoft 365 | PASS | Inbox |
| Yahoo | PASS | Inbox |
| Apple iCloud | PASS | Inbox |
| Proton | WARN | Spam |

## Frequently Asked Questions
### Why does my mail land in Gmail's Promotions tab?

Promotions is not spam — the message was delivered. Gmail sorts on content signals: heavy imagery, multiple tracked links, marketing language, and list-style headers. Transactional messages with a single clear purpose and minimal markup generally stay in Primary.

### Is a placement test the same as a spam score?

No, and the difference matters. A spam score is a heuristic guess from a scoring engine. A placement test sends a real message to real accounts and reports where each provider put it.

### How often should I test?

Before any significant change to sending — a new domain, a new provider, a new template family — and after any incident that affected your complaint or bounce rate.
