Cold email to businesses in the US
In the US, commercial email is covered by the CAN-SPAM Act, which does not require prior consent but does require honest sender details and subject lines, a valid physical postal address and a clear way to opt out. Opt-out requests must be honoured within ten business days, and some states add their own privacy rules. This is general information, not legal advice.
Riftjaw helps with the practical side: every record keeps its source and date, unsubscribes are honoured automatically and every campaign carries your sender details and an opt out link.

No. Riftjaw is not a data vendor. You collect the businesses yourself from public sources or your own files and import them. That is why the list is yours and why there is no credit meter on it.
If your file has an email column, that wins. If it only has websites, tick the prefixes you want, such as info@ and hello@, and Riftjaw derives addresses from each domain. Derived addresses are good guesses, not verified, so start with small batches.
Yes. The Free plan runs the whole pipeline on one list with small campaigns, and you do not need a credit card. Move to Pro when you want more lists, segments and bigger campaigns.
Yes. Put the US in its own segment, or keep a City field and save a filter such as city contains the US. You always see which part of the market you already worked.
