Why fresh data outperforms old data, every time
Email data decays at roughly 2–3% per month as people change roles. That compounds: a list that was 98% deliverable in January can be well below 90% by summer.
This is why we put a Last-updated badge on every bundle and refresh on a rolling basis. You should always know how recent a list is before you buy it.
The practical takeaway: buy fresh, and send soon. A verified list emailed this week will beat a bigger, older list every time.
