Inbox Placement Testing: What It Is and How to Run One

Inbox placement testing checks where a specific email actually lands — primary inbox, spam folder, or promotions tab — across major providers, as opposed to whether it merely sent without bouncing. A send with a 0% bounce rate can still land entirely in spam; delivery and placement are different measurements.

Sender reputation, domain authentication, and content signals all shift placement independently of each other. Testing placement before a full send catches a misconfigured DMARC record or a reputation problem while it only affects a handful of test inboxes, instead of an entire campaign.

Aimly Audit checks sender authentication (SPF, DKIM, DMARC), domain reputation, and blocklist status in one report, and flags the specific configuration issues most likely to affect placement before you send a campaign — rather than after deliverability has already dropped.

• SPF, DKIM, and DMARC validation with DNS-level detail
• Domain blocklist checks
• A single deliverability score and report you can act on

Run a check on your sending domain with Aimly Audit at https://audit.aimly.online/ before your next campaign, then re-check after any DNS or sending-provider change — placement issues are far cheaper to fix pre-send than mid-campaign.
