When a Prebuilt List Fits
A prebuilt list fits when the segment maps to standard attributes, for example marketing directors at software companies with 200 to 1,000 employees in the United States. The filters isolate that group, and the list downloads in minutes.
When BeSpoke Fits
BeSpoke fits when the filters return too few matches or miss the segment entirely. Examples include a certification paired with a company-size band, a named-account list for account-based marketing, a geography below state level, or an off-menu job title the standard role filter does not isolate.
Both Carry the Same Guarantee
Prebuilt lists and BeSpoke lists both carry BookYourData's 97% deliverability guarantee, and BookYourData returns credits for records beyond the guarantee. Read what BeSpoke list building is, or how BookYourData builds custom lists with BeSpoke.
