I’m getting ready to launch cold email campaigns across 24 highly segmented data feeds, targeting CIOs and C-suite executives at $1B+ enterprise companies for B2B IT consulting. Because we’re going after high-level enterprise decision-makers, authority and brand image are extremely important. I recently had a custom banner image created (attached below) to build immediate confidence and trust right when the email opens. Years ago, when our business was doing $4M/year, we ran emails through ConstantContact with visual banners and saw great success. However, standard cold email consensus today is: "Never include images in your first email—it will tank deliverability straight to spam." Here is our current setup: Accounts are pre-warmed (purchased directly through Instantly). Extremely low/sparing sending volume per inbox. Highly optimized spintax and copy to avoid traditional spam triggers. Deeply segmented firmographic data. At the same time, I regularly receive newsletter-style outbound emails in my primary inbox that feature visual header banners. I’d love feedback from anyone running B2B enterprise outreach: 1. Have you tested using a header banner or image in Email #1 when targeting enterprise C-suite? 2. Did you notice a measurable drop in deliverability (especially against enterprise filters like Proofpoint, Mimecast, or Microsoft Defender)? 3. If you use visuals, do you keep Email #1 strictly text-only and introduce graphics in follow-up steps, or do you use them from day one? Would appreciate hearing real test data or experiences from the group!
