Email Structure

Email Signature

A block of text or HTML appended to the end of emails, typically containing sender identification and contact information.

Definition

An email signature is a standardized block of content automatically appended to the end of emails. It typically includes the sender's name, title, company, contact information, and sometimes promotional elements like social links or legal disclaimers. In email marketing, signatures add a human touch and provide additional ways for recipients to connect.

Why It Matters

A professional signature adds credibility and humanizes automated emails. It provides multiple contact paths for recipients who want to respond or learn more. Signatures can also include legally required elements like physical address (required by CAN-SPAM) or privacy links (required by GDPR).

How It Works

Signatures are either manually added to individual emails or automatically appended by your email client/platform. Marketing emails often use branded HTML signatures with logos and styled contact information. The signature should be visually consistent with your email template.

Best Practices

  • 1Keep signatures concise - essential information only
  • 2Include required legal elements (physical address, unsubscribe link)
  • 3Make contact information clickable (mailto links, phone links)
  • 4Use consistent branding with your emails
  • 5Consider a personal signature for relationship-building emails

Frequently Asked Questions

Essential: name, title, company. Recommended: phone, email, website. Optional: social links, scheduling link, logo. Required: physical address and unsubscribe (usually in footer, not signature). Keep it scannable.

It depends on the email type. Personal-feeling emails (founder messages, sales outreach) benefit from signatures. Branded newsletters may use footer branding instead. Match the tone - casual emails warrant casual signatures.
