Is it safe to use emojis in the email 'from name' field?

Summary

Using emojis in the email 'from name' is generally considered a risky practice due to potential deliverability issues, compatibility problems across email clients, and security concerns. While some tests suggest it might be safe in certain circumstances, the consensus leans towards caution. Emojis might increase engagement, but they can also trigger spam filters, render incorrectly, or be exploited in display name attacks. Major email providers and email marketing experts recommend thorough testing, considering brand alignment, and prioritizing compatibility over visual appeal. Stick to standard ASCII characters whenever possible, and educate users to verify the sender's actual email address.

Key findings

  • Deliverability Risk: Emojis can increase the likelihood of being flagged as spam, especially if irrelevant or overly promotional.
  • Compatibility Problems: Not all email clients and devices render emojis correctly, leading to display issues and a poor user experience.
  • Security Vulnerability: Unicode characters, including emojis, can be exploited in display name attacks for phishing purposes.
  • Brand Perception: Emojis might be perceived as unprofessional if they don't align with the brand's identity.
  • Testing Inconclusive: Inbox placement tests show mixed results, indicating that emoji safety varies by email provider.

Key considerations

  • A/B Testing: Always conduct A/B tests to assess the impact of emojis on deliverability, open rates, and overall campaign performance.
  • Email Client Testing: Thoroughly test how emojis render across different email clients (Gmail, Outlook, Yahoo, etc.) and devices.
  • Brand Alignment: Ensure that emojis align with your brand's voice, target audience, and overall marketing strategy.
  • User Education: Educate users to carefully verify the sender's actual email address and report suspicious emails.
  • Stick to Standard Characters: Prioritize using standard ASCII characters in the 'from name' for maximum compatibility and security.
