Process

  • We match your file against our permission-based email databases to ensure the email provided belongs to the exact contact listed—not just anyone from their company.

  • To further improve accuracy, we use a domain pattern matching process. First, we identify the company’s email domain from your file. Then, using reference databases, we determine the company’s email format (e.g., firstname.lastname@company.com or firstname@company.com). Once identified, we generate the precise email address for your business contact.

  • After processing, a welcome email is sent to your customers, introducing your communications and offering an opt-out option.

  • When the process is complete, we return your enhanced file—ready for you to leverage in multi-channel marketing campaigns for maximum results.

  • Pay Only for Results – You only pay for e-mail addresses that are successfully appended, deliverable, and have received an opt-out message and decided not to unsubscribe from your e-mail list.

  • 100% Permission-Based – All emails are fully opt-in, ensuring compliance and trust.

  • High Match Rates – Achieve match rates ranging from 35% to 80%+.

  • Cost-Effective Investment – Pay solely for successful, deliverable results.

  • Strict Quality Control – All CASS standardization and customer matching are performed in-house.

  • No Middleman – Direct processing through our proprietary in-house database.

  • 5-Day Guarantee – We guarantee deliverability for all appended emails.

  • Fast Turnaround – Match reports delivered within 48 hours.

  • Free Match Test – No obligation—see potential results before committing.
