Pulse guides you through mapping your columns before the healthcheck begins. - ### Can Pulse match incomplete or outdated records? Yes. Pulse compares multiple business details and uses historical information, spelling variations, abbreviations and other contextual signals to identify the most likely business. Each result is assessed for confidence, with uncertain matches kept separate. - ### What will my Pulse healthcheck show? Your report shows the condition and coverage of your data, including business status, duplicate records, validation problems, missing information and what can be added. You can also explore patterns across sectors, locations, company sizes and turnover ranges. - ### Can Pulse identify dissolved or changed businesses? Yes. Pulse checks your records against current UK business information to identify live, dissolved and changed businesses. It can also highlight previous names, addresses and telephone numbers that may need updating. - ### What information can I add to my file? For matched businesses, Pulse shows the company details, named contacts, verified emails, job titles, social profiles and specialist information available to add. You can choose from more than 360 company, contact and specialist fields. - ### Do I have to purchase every available field? No. You can review what is available and select only the fields and contacts that are useful to you. This gives you control over what is added and what you pay for. - ### Can Pulse help me find new prospects? Yes.
