Frequently Asked Questions #
What is the average cold email open rate in Luxembourg?
The median cold email open rate in Luxembourg for 2026 is 18%, with the typical range running 14–22% for well-targeted B2B campaigns. Verified-only lists and native-French subject lines push performance toward the upper band; cold lists with poor verification land near the floor.
Why is Luxembourg's open rate around the global average?
Luxembourg sits in the strict compliance tier, which demands explicit opt-in for most B2B contacts. Luxembourgish business culture is formal, multilingual, and internationally oriented. Together these shape the observed open rate distribution.
When is the best time to send cold email in Luxembourg?
Send Tuesday through Thursday in the 9:00-11:00am local window. Tuesday, Wednesday, Thursday consistently outperform Mondays and Fridays in Luxembourg. Time-zone alignment matters more than absolute send time — schedule against the recipient's local morning, not your own.
What hard bounce rate is acceptable for Luxembourg?
Keep hard bounces below 2.5%. Above that level, ESPs (Gmail, Outlook 365) start throttling subsequent sends and your domain reputation degrades within days. Verify lists with SMTP-level checks before launching Luxembourg campaigns.
How do I improve cold email open rates in Luxembourg?
Three levers, in order of impact: (1) list quality — verified, decision-maker-targeted lists with current titles; (2) language match — subject lines in French when possible, even if the body is English; (3) send-time alignment with 9:00-11:00am. Luxembourg B2B cold email in English or French (both official) reaches the international financial community effectively.
