Bought lists: pros
- fast — data is ready immediately
- broad — large databases cover many industries
- B2B depth — good for larger companies and job titles
Bought lists: cons
- stale data — collected months ago; businesses close, people move
- shared — other buyers email the same contacts
- weak on small businesses — local businesses and creators are often missing or outdated
- compliance questions — you may not know how the data was collected
- bounces — old lists often bounce more, hurting deliverability
Building your own: pros
- fresh — collected from the live source when you search
- targeted — exactly your niche, location and signals
- unique — your filters and timing create a list others don't have
- transparent — you know where each detail came from
Building your own: cons
- takes a few minutes per search
- you need a tool to enrich with emails and owners
With Prospect Cheap the second con goes away: enrichment is included, and searches run in the background.
When buying makes sense
If you sell to mid-size or enterprise companies by job title, B2B databases are a reasonable choice. For local businesses, creators, advertisers and early startups, live sources usually win.
A middle path
Some teams combine both: a B2B database for larger accounts and job titles, and live lists for local businesses, creators and new startups. What matters is choosing the source where your customers are actually listed — and keeping the data fresh.
Questions to ask any list seller
- When was the data collected, and how often is it updated?
- Where did it come from?
- What share of emails bounce?
- Is the same list sold to other buyers?
