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.
