Zorraquín + Meneses y Asociados, one of the most prestigious agribusiness consultancies in Argentina with over 15 years in the market, was losing its most valuable channel without knowing it: the inbox. We found the problem in the numbers, not in the design.
Z + M was hitting a technical ceiling: its contact network was shrinking every month and its infrastructure was blocking access to the inbox. We identified a linear drop in subscribers and a malformed SPF record that invalidated the authentication of its mailings. We also found that corporate mailboxes were dying five times faster than personal ones, accumulating 8.4% non-existent addresses that put the account's reputation at risk.
We applied our engineering methodology to streamline the process, overcoming display limits through internal APIs. We verified thousands of contacts individually and corrected the domain's technical configuration in minutes.
Full technical audit of the sending infrastructure. Individual verification of thousands of contacts via internal APIs. Domain configuration fix (SPF).
Massive expansion: total safe sending reach rose to +80%. Corporate quality: we multiplied the business decision-maker segment by 3.4. Traceability and cleanliness: 100% new contacts, thousands of dead addresses removed before the first send. Channel optimisation: verified lists open 57% more on some days, 75% more on others.
After ten years of partnership, Z+M today has a proprietary data infrastructure that ensures its expert voice effectively reaches those who make the decisions.
