COMMON QUESTIONS
Everything you need to know before you get started.
Where do the prospects come from?+
We research business directories, company websites, company records and approved contact-data sources around your agreed specification.
Are all emails verified?+
Records counted as verified-contact deliveries pass an independent work-email verification stage. Risky or incomplete records can be withheld or routed for review.
Can you avoid people already in my CRM?+
Yes. Existing customers, prior contacts, opt-outs and other suppression records can be supplied for exclusion before delivery.
Can Keystone send the outreach too?+
Yes. The Complete Outbound System can connect approved prospects to company-specific email sequences, reply handling and CRM follow-up.
How does n8n relate to the service?+
Keystone can use n8n within an installed system. Managed-service customers simply receive the agreed prospect delivery.
