Email Design Email Signature 3 — Questions and Answers
Question 1: Why should phone numbers in an email signature be formatted as tel: links?
- Mobile recipients can tap to call directly (Correct answer)
- It prevents spam bots from reading the number
- It reduces the signature's file size
- It is required for the number to display on iPhones
Correct answer: Mobile recipients can tap to call directly
A tel: hyperlink lets mobile users start a call with one tap, improving usability on smartphones.
Question 2: An employee's signature renders with huge gaps between lines in Outlook but looks fine in Gmail. What is the most likely cause?
- Outlook interprets paragraph tags with default margins differently than Gmail (Correct answer)
- Outlook blocks all HTML signatures
- Gmail compresses whitespace illegally
- The signature exceeds Outlook's character limit
Correct answer: Outlook interprets paragraph tags with default margins differently than Gmail
Outlook's Word-based rendering engine applies its own default spacing to paragraph tags, so line breaks or margin resets are needed.
Question 3: What is the recommended way to handle social media icons in a signature?
- Use small, web-hosted icon images linked to profiles, limited to the most relevant networks (Correct answer)
- Embed each network's official JavaScript widget
- Include every social network the company has ever used
- Use animated GIF icons for all networks to attract attention
Correct answer: Use small, web-hosted icon images linked to profiles, limited to the most relevant networks
A few small hosted icons linked to active profiles keep the signature clean, functional, and lightweight.
Question 4: Why is it better to host signature images on a server rather than attaching or embedding them?
- Attached images can appear as paperclip attachments and inflate every message's size (Correct answer)
- Hosted images are immune to being blocked
- Embedded images violate email standards
- Servers automatically resize images per device
Correct answer: Attached images can appear as paperclip attachments and inflate every message's size
Embedded or attached images bloat each email and often show as confusing attachments, while hosted images keep messages light.
Question 5: Which font strategy is safest for an email signature?
- Web-safe fonts like Arial or Georgia with fallbacks in the font stack (Correct answer)
- A custom brand font loaded via @font-face only
- Any Google Font without fallbacks
- Images of text rendered in the brand font for all content
Correct answer: Web-safe fonts like Arial or Georgia with fallbacks in the font stack
Web-safe fonts with fallback stacks render consistently everywhere, since many clients ignore @font-face.
Question 6: A sales rep's signature contains a scanned handwritten signature image. What is the primary security concern?
- The image could be copied and used to forge documents (Correct answer)
- Scanned images always contain viruses
- Handwriting cannot be legally sent by email
- It makes the email fail SPF checks
Correct answer: The image could be copied and used to forge documents
A real handwritten signature image can be extracted and misused for forgery, so most experts advise against including one.
Question 7: What is the purpose of centrally managed signature software in a company?
- Enforcing consistent branding and legal disclaimers across all employees automatically (Correct answer)
- Encrypting all outgoing email
- Preventing employees from sending personal email
- Reducing mail server storage costs
Correct answer: Enforcing consistent branding and legal disclaimers across all employees automatically
Central signature management pushes uniform, compliant, on-brand signatures to every mailbox without relying on individual employees.
