Yes - seriously.
Most people spend hours optimizing subject lines, first lines, CTAs…
Then destroy their deliverability with a bloated, risky signature.
Here’s what not to do in a cold email signature:
- Images (especially profile pics or logos)
- 3-5 links to socials, booking tools, websites
- Fancy formatting, bold colors, or HTML signatures copied from Gmail
ESPs filters love minimalism.
Every extra element is a potential spam trigger.
Here’s what your signature should look like in cold outreach:
→ Plain-text email
→ First name + role
→ Company name (no hyperlink)
→ No images, no quotes, no banners
Example:
Margaret Sikora
CEO @ Woodpecker.co
Keep it plain. Keep it short. Keep it unbranded.
Your signature isn’t a branding opportunity.
It’s a deliverability risk.
Don’t let your signature kill your campaign.
