FAQ

Cold outbound in Spain: questions

How many companies in Spain run cold outbound?

480 have at least one sending domain that redirects to them; 15 added three or more in the last 30 days.

How do you know?

Cold e-mail is sent from lookalike domains, never from the main domain. We read new domains from certificate-transparency logs, check their DNS for cold-email infrastructure and follow the redirect to the company.

Does absence mean no cold e-mail?

No. Teams sending from their main domain or through platforms without a DNS trace are not counted.
