1stBase is committed to maintaining the accuracy, depth and freshness of its focused sector databases.

We complete 1,000s of telephone research interviews to update key data fields that yield invaluable information for our clients. All 1stBase database content is processed through sectorResultsTM™ and through 1stBase's database systems and disciplines.

We suggest clients use the most recent updates of our refreshed sector databases. As a result, we are confident that 1stBase offers the highest level of quality available, backed with a 97% deliverability guarantee. For returns on any direct mail or telemarketing campaign based on 1stBase databases exceeding 3%, we deliver a No Quibble Reward (or credit toward a future purchase) of the pro rata price of each record for each piece above the initial 3% returned.

Because of the fast-moving nature of email addressing, this offer does not apply to email campaigns. For direct mail and telemarketing, the offer applies to the portion of the campaign that uses 1stBase content and 1stBase will request samples in order to validate the claim and to ensure that proper corrective action is put in place. The refund applies to mailings that were completed using the most up-to-date version of 1stBase data.
