Follow these troubleshooting steps to identify a cause when an Everest inbox test appears with 100% missing results.
- Confirm that you are sending to the entire Everest seed list including all four unique reference seed addresses. You can view your reference addresses and download the latest version of the seed list by navigating to In-Flight>Inbox Placement>Manage Seed List.
- Ensure your test email has an x-header or HTML body tag ID by opening the email in Inbox Tests (In-Flight>Inbox Placement>Inbox Tests). The ID helps Everest identify all the seeds associated to a campaign. Everest automatically detects IDs from many ESPs, but be sure to implement one if this value is missing from your test campaign. An ID is especially important for A/B testing or if you see duplicate versions of the same campaign.
- Ensure your Everest seed list addresses are not being suppressed by your ESP. The Everest seed list addresses only engage with your email when checking links and images and do not engage with your email in a way that will register with your ESP. This lack of engagement may result in the ESP suppressing the seed addresses.
- A specific mailbox provider may be blocking your email. Check your SMTP error codes from the affected mailbox provider to see if a block is in place. Most mailbox providers provide an error code number and a link you can use to get more information about the cause of the block.
- Ask your email administrator or ESP for a list or report of these error codes for the affected test campaign.
- You can also use Everest to check if your IP or domain is on a third-party blocklist by navigating to Monitoring>Reputation and clicking View Report on the Blocklisted tile. Fix the cause and submit a delist request if you are on a high priority blocklist.
