Why this signature is deliverability-safe
No images, no tracking pixels, no nested tables, three of the biggest spam-filter triggers in cold email signatures.
Why most email signatures hurt cold outreach
Heavy HTML signatures, logos, banners, social icons, disclaimers, increase your message size, trip spam filters and look like marketing email to filters like Google's. For cold email, you want a signature that reads like a real person sent it.
Rules for a deliverability-safe signature
- No images. Image-heavy signatures correlate strongly with spam folder placement.
- No tracking pixels. Open-tracking pixels in the signature are one of the most reliable spam triggers in 2026.
- Keep it under 4 lines of text.
- Use plain links, not button-style CTAs.
- Include a real reply address and, ideally, a calendar link.
