Your email signature is the last thing the reader sees. It's also the first thing spam filters scan for "marketing email." A minimal, human-looking signature helps deliverability and conversion. A corporate signature with logo, banners, social icons, and disclaimers does the opposite.
The minimal signature
What works for cold B2B in 2026:
Minimal signature
Sam
Sam Ochoa
[Title], [Company]
[City, State]
Four lines. Name, title, company, location. Nothing else.
Why this works
Feels like a person. Colleagues don't email each other with 12-line corporate signatures.
Deliverability. Signature blocks with logos, banners, social icons, legal disclaimers trigger promotional/marketing classifiers.
No distraction. The CTA is in the email body, not competing with "Follow me on LinkedIn!" links.
What to leave out
Logo, image in email = higher spam score. Text-only.
Banner ads, "Check out our latest webinar" below the signature = marketing flag.
Legal disclaimers, "This email is confidential...", if required by your role, keep brief; it's a spam signal.
Phone number, most cold reply paths go through email, not phone. Add to follow-ups if useful.
Social icons, sophisticated LinkedIn icons, Twitter icons, etc. flag as marketing.
Quote of the day, no.
Award badges, no.
Progressive signatures across sequence
A small technique: add one element per email across the sequence to signal continuity without cluttering:
Email 1: minimal (name, title, company, location)
Email 2-3: add phone number
Email 4+: add a link to one relevant resource (case study or LinkedIn profile)
The "replying from phone" trick
"Sent from my phone, excuse brevity and typos" at the end of cold emails feels personal and explains casual tone. Do not overuse. Legitimate when you are on phone; fake when everyone does it.
For regulated industries
Some industries require specific disclaimers in email (financial services, healthcare, legal). Keep them brief, use small grey text, and place after a line break:
Compliant minimal signature

Sam Ochoa
Licensed Agent | [Company]
[City, State]

Where compliance requires more, work with your firm's compliance team, never trim legal requirements to optimize deliverability.
The one-line description
Some operators add a single line of "what I do" under their title:
Signature with one-line positioning
Sam Ochoa
Pipeline & ramp consultant for B2B SaaS teams
San Francisco, CA
Works when your positioning is clear and specific. Skip if it sounds like a tagline.
The recipient's test
Read your signature as a recipient. Does it look like a peer emailed you, or does it look like a marketing email? If there's any question, trim.
What to do with this
Strip your signature to name + title + company + one optional link, more than that reads as marketing and triggers filters
Never attach a logo image on cold email 1, images contribute to spam scores and pattern-match to promotional emails
Match signature tone to the email tone, a peer-style email with a corporate-branded signature reads dissonant
Include the unsubscribe in small footer text, legal requirement + signals legitimacy to recipients
Test your signature visually in GMail, Outlook, and mobile, signatures that look fine on desktop often break on phones
