Every tool here is free and needs no account. We build them because most senders have never actually measured their deliverability — and you can't fix what you haven't seen.
Authentication passing doesn't mean you're inboxing. Our team runs a full placement test — the exact share of your email reaching the inbox versus spam across Gmail, Outlook and Yahoo — then sends the fixes ranked by revenue impact.
Someone from our team will send your full placement report within one business day. If it isn't in your inbox, check spam — and that tells us something too.
Send to our seed addresses and see exactly where your mail lands — inbox, promotions or spam — across Gmail, Outlook and Yahoo, read from the real message headers.

Every tool here tells you the truth about your own sending, whether or not you ever hire us. Most people find something broken, fix the easy parts themselves, and come back when they hit the part that needs a specialist. That's a fair trade.
It takes 60 seconds and asks for nothing. The full placement test comes back within a day.
