Will censoring spicy language in emails prevent spam triggers?

Summary

The consensus from experts, email marketers, and documentation from major email providers indicates that censoring 'spicy' language in emails is not a primary or effective strategy for avoiding spam filters. While avoiding overtly spammy language is prudent, the key factors for email deliverability are sender reputation, content quality, user engagement, email structure, and IP address. Drastic changes in design may negatively impact reputation, and while nannyware might be triggered, spam filters are unlikely to be significantly affected by simply censoring words.

Key findings

  • Reputation is Paramount: Sender reputation is the most critical factor influencing email deliverability.
  • Content Engagement: Engaging content and user interaction (opens, clicks) significantly improve deliverability.
  • Limited Censoring Effect: Censoring individual words has a minimal impact on spam filtering compared to broader factors.
  • Holistic Analysis: Spam filters analyze multiple factors, including IP address, domain reputation, and email structure.
  • Potential Nannyware: Spicy language is more likely to trigger nannyware than spam filters.

Key considerations

  • Reputation Management: Prioritize building and maintaining a positive sender reputation through consistent sending practices and authentication protocols (SPF, DKIM, DMARC).
  • Quality Content Creation: Focus on crafting high-quality, relevant content that resonates with your target audience.
  • Engagement Strategies: Implement strategies to encourage user engagement, such as personalized content, clear calls to action, and interactive elements.
  • Email Structure Optimization: Ensure your email structure adheres to best practices and avoids common spam triggers.
  • Avoid Drastic Changes: Be cautious of making sudden and drastic changes to your email design or content, as this can negatively impact your reputation.

The general consensus is that while avoiding overtly spammy language is important, simply censoring 'spicy' language is not a primary factor in preventing emails from being flagged as spam.

Key opinions

  • Sender Reputation: A strong sender reputation is crucial for email deliverability, outweighing the impact of individual words.
  • Engaging Content: Content that recipients find valuable and engaging is more likely to bypass spam filters.
  • Audience Engagement: High engagement rates, such as opens and clicks, positively influence deliverability.
  • Design Changes: Sudden and drastic changes in email design can negatively impact deliverability.
  • Censoring Impact: Censoring words alone is not a reliable strategy; it's more important to avoid overtly spammy language and build a positive sender reputation.

Key considerations

  • Reputation First: Prioritize building and maintaining a positive sender reputation through consistent sending practices and authentication protocols.
  • Content Quality: Focus on creating high-quality, relevant content that resonates with your audience.
  • Monitor Engagement: Actively monitor engagement metrics and adjust your sending strategy based on recipient behavior.
  • Avoid Drastic Changes: Be cautious with sudden shifts in email design and content, as these can trigger spam filters.
  • Context Matters: Consider the context of your language and audience expectations; some level of 'spicy' language may be acceptable depending on your brand and audience.
