smaller, targeted lists with genuine intent signals will outperform any scraped megafile nine times out of ten. Relevance trumps volume every time, and I've seen that play out across dozens of accounts I've audited. my rule of thumb is one strong trigger - say, a recent job change or a spike in page visits - paired with one supporting signal, like a specific content download. everything beyond that belongs in a nurture sequence, not the initial outreach. Sending five emails with three different personalisation angles just because you have data is how you end up on blocklists.
Also, fully agree on the "spam" complaint angle. when i dig into delivery logs, most flagged messages aren't even hitting spam filters - they're getting caught because the recipient has already marked one email from the same cadence before. that's cadence fatigue, not spam. And generic video thumbnails? They're the new "I noticed you downloaded our whitepaper" line. Unless the video literally opens with their name and a reference to their specific problem, they can smell the batch-and-blast from a mile away.
