Why do political campaign emails go to spam?

Summary

Political campaign emails often end up in spam due to a confluence of factors. These include poor list quality (purchased or outdated lists), aggressive and frequent solicitation practices, emotionally charged language and spam trigger words, and lack of explicit permission. These practices contribute to low engagement, high complaint rates, and a damaged sender reputation. Email providers like Gmail and Microsoft consider these factors, along with user feedback, when filtering emails. Sending from newly created or unauthenticated domains also increases the likelihood of being marked as spam. To improve deliverability, campaigns need to focus on building clean, permission-based lists using double opt-in, segmenting audiences for personalized content, implementing proper email authentication (SPF, DKIM, DMARC), practicing good list hygiene, and avoiding spam trigger words. Emphasizing relevance, clear communication, and pathological empathy towards the audience are also crucial.

Key findings

  • Poor List Quality: Purchased or outdated email lists lead to low engagement and higher spam report rates.
  • Aggressive Solicitation: Frequent emailing and aggressive fundraising tactics frustrate recipients and trigger spam filters.
  • Content Issues: Emotionally charged language, spam trigger words, and irrelevant content contribute to spam flagging.
  • Lack of Permission: Sending emails without explicit permission harms sender reputation and increases spam placement.
  • Authentication Failures: Lack of SPF, DKIM, and DMARC authentication makes it difficult for email providers to verify sender identity.
  • Negative User Feedback: High complaint rates and spam reports significantly impact deliverability.
  • Engagement Deficit: Low engagement metrics, such as opens and clicks, signal a problem to email providers.

Key considerations

  • Obtain Explicit Permission: Build email lists based on explicit consent, using double opt-in methods.
  • Practice List Hygiene: Regularly clean email lists by removing unengaged subscribers.
  • Personalize Content: Segment audiences and tailor email content to improve engagement.
  • Implement Authentication: Set up SPF, DKIM, and DMARC to verify sender identity and improve deliverability.
  • Avoid Spam Triggers: Refrain from using spam trigger words and emotionally charged language in email content.
  • Monitor Reputation: Monitor sender reputation and address any issues promptly.
  • Prioritize Engagement: Focus on creating engaging and valuable content that encourages opens and clicks.

Political campaign emails frequently land in spam folders due to several interconnected factors. These include the use of low-quality, often purchased, email lists; aggressive and frequent email campaigns, sometimes employing emotionally charged language that triggers spam filters; and a lack of focus on recipient engagement.

Political campaign emails are often filtered as spam due to a combination of factors considered by email providers' spam filters. These factors include sender reputation, content quality, user feedback (spam reports), high complaint rates, low engagement, and sending from newly created or unauthenticated domains. Real-time blocklists (RBLs) identify and block known spam sources, potentially blocking campaign emails if their IP or domain is listed. Implementing Sender Policy Framework (SPF) records and DomainKeys Identified Mail (DKIM) helps verify the authenticity of emails, improving deliverability and reducing the risk of being marked as spam.

Key findings

  • Sender Reputation: Poor sender reputation significantly increases the likelihood of emails being filtered as spam.
  • User Feedback: High spam report rates from users negatively impact email deliverability.
  • Engagement Metrics: Low engagement rates (e.g., opens, clicks) contribute to emails being marked as spam.
  • Authentication: Lack of proper email authentication (SPF, DKIM) can lead to deliverability issues.
  • Real-time Blocklists: Listing on real-time blocklists (RBLs) results in emails being blocked or sent to spam.

Key considerations

  • Improve Sender Reputation: Focus on building and maintaining a positive sender reputation through consistent engagement and positive user interactions.
  • Monitor User Feedback: Actively monitor and address user feedback and spam reports to identify and resolve deliverability issues.
  • Increase Engagement: Implement strategies to improve email engagement, such as personalized content and targeted messaging.
  • Implement Authentication: Ensure proper email authentication (SPF, DKIM) is in place to verify the authenticity of emails.
  • Avoid RBLs: Take steps to avoid being listed on real-time blocklists by adhering to best practices for email sending and list management.
