Your prospect list is growing, but your open rates keep slipping.<\/p>\n\n\n\n

If you\u2019re running structured outreach campaigns, there\u2019s one silent killer behind the dip in performance: inactive subscribers.<\/p>\n\n\n\n

They’re not just sitting idle; they’re quietly wrecking your deliverability and draining pipeline potential.<\/p>\n\n\n\n

In this guide, we\u2019ll break down the real, data-backed impact of inactive contacts and why ignoring them could be costing your team qualified leads, productivity, and serious revenue.<\/p>\n\n\n\n

Let\u2019s break down how this happens, starting with how email providers<\/a> judge you.<\/p>\n\n\n\n

How inbox providers evaluate your sender reputation<\/h3>\n\n\n\n

Email providers like Gmail and Outlook don\u2019t manually decide where your emails land; they rely on algorithms. <\/p>\n\n\n\n

These algorithms look at specific signals to decide whether to put you in the inbox, promotions tab, or spam.<\/p>\n\n\n\n

Here are the signals they\u2019re tracking:<\/p>\n\n\n\n
