The trigger
A long-time buyer in EU asked, in a polite reply, why every link in the newsletter went through a tracking redirect that flagged in his corporate firewall. Marco, the second-generation owner, didn't know. He spent a Tuesday afternoon reading what his ESP did by default and was unhappy with what he found.
The migration
CSV export Friday evening. Imported into BLUN · Mailing Monday morning — de-duplicated against bounces, country-tagged from the address fields, opt-in dates preserved for the GDPR audit trail. Domain warmup ran on the DE-NUE pool for nine days.
The first send — a Q1 collection preview — went to 1,802 contacts. Open rate jumped from 33% on the old tool to 41% on BLUN · Mailing. Marco ascribed it to the cleaner sender domain; we ascribe it to the dropped tracking pixel making the body lighter.
The flow that runs every Tuesday
One automation: tag-added "leather-buyer" → 30-min delay → personalised greeting in IT or DE → 7-day delay → product preview block. 218 contacts in flow at any given moment, 642 completed since launch, 3,557 €/mo of attributable revenue.
