Follow-up mailing audiences outperformed first-time mailed audiences in 88% of campaign periods — and in all remaining periods, performance was tied. Follow-up mailings generated a new customer response rate 43% higher than first-time mailings on average. Crucially, average sales value remained stable, confirming that the lift in response came without sacrificing customer quality.

OVERVIEW
Gundir demonstrated how repeat mailings improve campaign ROI.
The Challenge
Driving B2B response with a limited addressable market
The client needed to drive stronger B2B response without relying solely on fresh names. Many B2B marketers face a limited total addressable market (TAM), making a robust remail strategy essential. A fresh-names-only approach can leave value on the table by overlooking prospects who have already been introduced to the brand but have not yet acted.
The Solution
Structured remail strategy on a recurring cadence
Gundir implemented a follow-up mailing strategy designed to re-engage qualified business contacts who had previously received a direct mail piece but had not yet converted. Rather than treating direct mail as a one-time interaction, the program leveraged repeat exposure to keep the brand top of mind. Performance was tracked by comparing first-time and follow-up mailing audiences across multiple campaign periods.
The Results
Consistent response lift with no drop in customer quality
