New Data Reveals How Banking Email List Accuracy Impacts Lead Conversion Rates | InfoGlobalData

Or:

Correct accounting firm → wrong department → irrelevant software pitch → ignored email

Even a valid address can be commercially inaccurate if the recipient no longer influences the purchase.

Poor data can also create operational costs. Salespeople may need to:

1. Check whether the accountant still works for the firm.
2. Verify the current role.
3. Search for a replacement contact.
4. Correct the CRM.
5. Remove duplicates.
6. Restart the outreach sequence.

Validity's 2025 research shows why these issues deserve management attention: 37% of surveyed CRM users reported revenue loss associated with poor data quality. (Validity)

That statistic is cross-industry, so it should not be interpreted as a specific conversion effect for accounting campaigns. It does, however, demonstrate that data quality can have commercial consequences.
