Email signature best practices (2025)

Email signature best practices (2025)

1. 1

   Keep it short — 4–6 lines maximum. Signatures longer than this get cut off or hidden by email clients.

2. 2

   Include your full name, role, and company at minimum — these are what recipients search for when looking you up.

3. 3

   Add one contact method beyond email — a phone number or website so people have options.

4. 4

   Use your brand's exact accent colour — consistency across every email builds recognition over time.

5. 5

   Skip the inspirational quote — it looks unprofessional in most B2B contexts and dates quickly.

6. 6

   Link social profiles only when relevant — LinkedIn for B2B, Dribbble or GitHub for creatives, Instagram for consumer brands.

7. 7

   Use a publicly hosted HTTPS URL for any photos or logos — email clients block local files and HTTP images.

8. 8

   Test in Gmail and Outlook before rolling out — both render HTML differently, and Outlook is the most restrictive.
