Inbox Test: See Where Your Email Lands Before You Send

Inbox Test

An inbox test seeds a message to real mailboxes across providers and reports which folder it lands in, so you can see placement before sending to your full list.

What it tells you

The folder distribution across providers: how much lands in inbox, promotions, or spam at Gmail, Outlook, Yahoo, and others. That's information your own logs can't give you, and it's the check to run before a large or important campaign.

When to run one

Before big campaigns, after any authentication or infrastructure change, and when troubleshooting a placement drop. Pair it with a spam test email for the content and authentication score behind the placement result.

How Nitrosend runs inbox tests

The first-party seed pool of about twenty real mailboxes across major providers is built in, so inbox testing is part of the platform rather than a separate service you send seeds to.
