Send a controlled Brevo test to Gmail, Google Workspace, Outlook, Microsoft 365, and Yahoo seed inboxes so you can see where the campaign lands before customers receive it.

Start a MailSlurp inbox placement test and copy its exact marker and current Gmail, Google Workspace, Outlook, Microsoft 365, and Yahoo recipients.
