Cold email to businesses in the UK
In the UK, B2B cold email is covered by the Privacy and Electronic Communications Regulations (PECR) and UK GDPR. PECR generally allows marketing email to corporate subscribers such as limited companies without prior consent, but sole traders and some partnerships are treated like individuals and usually need consent, and every message must identify you and offer a simple way to opt out. Under UK GDPR you also need a lawful basis, often legitimate interests, to use the details of named contacts. 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 UK in its own segment, or keep a City field and save a filter such as city contains the UK. You always see which part of the market you already worked.
