Guide
Email signature basics for outreach teams
What is an email signature?
An email signature is the closing block that identifies the sender, company, contact options, compliance links, and useful next steps. It appears after the message body and helps recipients understand who contacted them.
Why email signatures matter for deliverability
A clear signature supports trust and recipient experience. It also makes opt-out paths easier to find, which can reduce spam complaints and support healthier sending behavior.
What to include in a compliant email signature
Include sender identity, business name, website, contact details, a mailing address, and any opt-out or preference links your sending workflow requires. Keep the language direct and easy to scan.
HTML vs plain-text email signatures
HTML signatures can use links, spacing, and brand styling. Plain-text signatures are useful for simple campaigns, fallbacks, and highly direct outreach. Many teams keep both versions ready.
Email signature best practices
Use simple markup, inline CSS, readable contrast, short labels, and working URLs. Avoid script tags, external dependencies, oversized images, and cluttered legal text that hides important compliance links.
