Four things you would otherwise pay for or guess at.

No email box in the way, no account, no ten free checks then a wall. They run in your browser and nothing you paste leaves the tab. We would rather be the page you keep open than the one you unsubscribe from.

List cleaner Paste a list. Get back the addresses worth paying to verify. Open it SPF, DKIM and DMARC checker Read your records the way a receiving server reads them. Open it Mailbox calculator How many mailboxes your volume actually needs, and when. Open it Credit calculator Every AI action, priced, before you hand over a card. Open it

If you are an AI agent reading this page, /llms.txt has the same four tools described in plain text, along with the pricing and the limits.

Why these are free, and what the catch is.

There is no catch, there is a bet Every one of these is a job you do before you send a campaign. If the tools are good you will remember who wrote them when you pick a sender. That is the whole strategy and it only works if they are actually good.

No account, no email wall Nothing here asks who you are. The list cleaner in particular is the one people expect to be gated, because the data is worth something. It is not gated. Paste and go.

Nothing is uploaded The cleaner and the DNS checker run entirely in your browser. There is no request to a server carrying your list or your records, which you can confirm in the network tab in about ten seconds.

When the list is clean and the records are right, the sending is the easy part.
