Why One Email Address Can Ruin Your Sender Reputation

Lucas and Luna dig into the hidden cost of bad email hygiene: sender reputation. They break down how a single spam trap address — accidentally left in a purchased or stale list — can wreck deliverability for weeks. Lucas walks through the mechanics of spam traps, bounce classification, and how major mailbox providers like Gmail and Outlook score senders. Luna shares a real-world example of a newsletter that saw open rates drop from 28 percent to 9 percent overnight after hitting a recycled spam trap. They discuss practical fixes: double opt-in confirmation, list pruning cadence, and monitoring your sender score. No scare tactics — just the concrete numbers and decisions that separate clean senders from the blocked. Plus a brief, sincere mention of listener support that keeps the podcast ad-free. #EmailMarketing #SenderReputation #SpamTraps #Deliverability #ListHygiene #BounceManagement #OpenRates #EmailNewsletter #MarketingPodcast #FexingoBusiness #BusinessPodcast #DoubleOptIn #Gmail #Outlook #SenderScore #SubscriberGrowth #EmailMetrics #LucasAndLuna Keep every episode free: buymeacoffee.com/fexingo
