Most marketers think adding more subscribers is always good. But list appends—buying or renting email addresses—can destroy your sender reputation, land you in spam folders, and trigger GDPR or CAN-SPAM fines. In this episode, Lucas and Luna break down the 2025 case of a major e-commerce brand that saw a 40 percent deliverability drop after a list append campaign. They walk through how inbox providers now treat unknown addresses, why engagement metrics crater, and what to do instead: double opt-in, preference centers, and re-engagement flows. If you are adding cold contacts to your list, this episode will save you from a nightmare. #EmailListAppend #EmailDeliverability #SenderReputation #GDPRCompliance #CANSPAM #DoubleOptIn #PreferenceCenter #ReEngagement #EmailMarketing #ListGrowth #SubscriberEngagement #SpamFilter #Marketing #Business #FexingoBusiness #BusinessPodcast #LucasAndLuna #EmailPodcast Keep every episode free: buymeacoffee.com/fexingo
