The signature is the last thing anyone thinks about and one of the easier things to get wrong, because the instinct, look professional, include everything, produces exactly the artefact that makes a cold email look like a campaign.
What a cold email signature should be
Three lines:

That is it. Name, company, one link. Optionally a phone number if you genuinely want calls.
The reason is not minimalism as a style choice. A first cold email is trying to look like a message from a person, and a person emailing a stranger for the first time does not attach a logo, a banner, a calendar link, four social icons and a legal disclaimer. Every element you add moves the message from “someone wrote to me” towards “I have been added to a list”.
What to leave out, and why
| Element | Why not |
|---|---|
| Logo or banner image | Images in cold email are a commercial signal, and a hosted image is another external request in a message trying to look personal |
| Social icons | Four small images, no benefit. A text LinkedIn link if you must |
| Calendar link in the first email | Asks for commitment before permission. Save it for after a reply |
| Long disclaimers | Corporate furniture that makes the message look mass-sent |
| Quotes or awards | Adds length and says nothing to a stranger |
| “Sent from my iPhone” as a fake casual signal | Everyone recognises the trick |
On placement specifically: no single signature element will send you to spam, but a signature with several images, multiple links and heavy HTML pushes a message towards the promotions tab, which is functionally the same outcome for cold outreach. What actually affects placement.
The legal minimum
Requirements differ by jurisdiction and this is general information rather than legal advice, but the practical shape is consistent: identify who you are, make it possible to tell where the message came from, and give a plain way to opt out. Under CAN-SPAM a physical postal address is expected on commercial mail; GDPR and PECR are more concerned with lawful basis and an easy objection route than with signature contents.
A plain sentence, “If this is not relevant, reply with ‘no’ and I will not write again”, does more for both compliance and reputation than a paragraph of small print, because it produces a reply instead of a complaint.
Two signatures, not one
Cold first touch: the three lines above. Nothing else.
Live conversation: once someone has replied, the constraint disappears. Add the calendar link, the phone number, the job title, even a logo if your company insists. At that point you are corresponding, not prospecting, and looking established helps rather than hurts.
Most sequencers let you set this per step, and it is worth the two minutes: the signature that helps you close is the wrong signature for the first message.
Next: how to write the email above the signature, or what actually triggers filters.
Frequently asked questions
What should a cold email signature contain?
Name, company and one link, three lines of plain text. A phone number is optional if you genuinely want calls.
Should I use a logo in a cold email signature?
No. Images are a commercial signal in cold email and a hosted logo is another external request in a message that is trying to look personal.
Do signatures affect deliverability?
No single element will send you to spam, but several images, multiple links and heavy HTML push a message towards the promotions tab, which is the same outcome for cold outreach.
Should I include a calendar link?
Not in the first email, it asks for commitment before permission. Add it once someone has replied.
What is the legal minimum?
This is general information rather than legal advice, but in practice: identify yourself, make the origin clear, and offer a plain opt-out. CAN-SPAM expects a physical postal address on commercial mail.
