Deliverability & mailbox health
Inbox visibility test
Send a tagged test email from any connected mailbox to a network of seed accounts across providers, then see whether it landed in Inbox or Spam — a snapshot of current deliverability before you launch a real campaign.
How it works
A tagged test email is sent from your mailbox to a network of seed accounts across Gmail, Outlook, and other providers. Each seed account's inbox is checked shortly after to see whether the email landed in Inbox or Spam.
The process in Sendqube
- 1Go to Inbox Visibility Test and select mailboxes to test (capped per plan).
- 2Run a test — it sends to every active seed account and creates one check per mailbox.
- 3Results populate as seed inboxes are checked: Inbox, Spam, or Not found, with a placement score.
