Is using 'tracker' in a subdomain spammy?

Summary

The consensus is that using 'tracker' in a subdomain is technically not inherently spammy. However, it can raise concerns and distrust among more tech-savvy recipients due to the explicit nature of the term. A subdomain's reputation and sending practices have a greater impact on deliverability. Experts recommend transparency with recipients about tracking practices and suggest using more neutral or descriptive subdomain names like 'click,' 'link,' or 'image.' Shorter, branded subdomains can be preferred.

Key findings

  • Technically Not Spammy: Using 'tracker' in a subdomain is not inherently flagged as spam by mailbox providers or spam filters.
  • Perception Matters: The explicit nature of 'tracker' can raise privacy concerns and distrust among some users, potentially leading to increased spam reports or lower engagement.
  • Reputation is Key: A subdomain's reputation, determined by sending practices and engagement metrics, is more important for deliverability than the name itself.
  • Transparency is Recommended: Being transparent with recipients about tracking practices and intentions can help mitigate negative perceptions and build trust.
  • Alternatives Exist: More neutral and descriptive subdomain names, like 'click,' 'link,' or 'image,' can be preferable for avoiding negative connotations.
  • Subdomains are Separate: Email Providers treat subdomains are separate entities, which means that the best practices of other subdomains will not impact the tracker subdomain.

Key considerations

  • Audience Awareness: Consider your audience's technical knowledge, privacy sensitivity, and potential perceptions of 'tracker'.
  • Transparency Practices: Be transparent with recipients about what is being tracked and why, providing clear explanations and opt-out options.
  • Subdomain Naming: Explore alternative subdomain names that are more neutral, descriptive, or aligned with your brand, avoiding potentially negative connotations.
  • Reputation Management: Focus on building and maintaining a positive sending reputation for the tracking subdomain through responsible email practices.
  • Technical Best Practices: Implement proper authentication protocols (SPF, DKIM, DMARC) and adhere to email deliverability best practices to avoid being flagged as spam.

What the experts say
4Expert opinions

Experts suggest that while 'tracker' isn't inherently negative, alternatives like 'click,' 'link,' or 'image' may be preferable as they are neutral and descriptive. SFMC uses 'click.sub.domain.com' by default. Mailbox providers focus on engagement and the destination of the click, not the subdomain name itself. Transparency with recipients about tracking is crucial. If you are transparent, then it's acceptable.

Key opinions

  • Neutral alternatives exist: Terms like 'click,' 'link,' and 'image' are good alternatives to 'tracker'.
  • Transparency is key: Be upfront with recipients about tracking practices.
  • MBPs focus on engagement: Mailbox Providers prioritize engagement and the destination of the link.
  • SFMC default: SFMC uses 'click.sub.domain.com' by default.
  • Acceptable if transparent: Using the word 'tracker' is fine as long as your email recipients understand what is being tracked and why.

Key considerations

  • Choose descriptive names: Select a subdomain name that clearly indicates its purpose.
  • Prioritize transparency: Ensure recipients are aware of and comfortable with tracking practices.
  • Consider mailbox provider focus: Focus on engagement and avoid linking to spammy sites.
  • Audience Awareness: Be aware that despite efforts to make things clear, not all recipients will know what is happening even when its clear to the marketer

Expert from Email Geeks shares that they prefer names like link (lnk, lk), image (img, im), click (clk, ck,), etc... to be descriptive enough, but not too stalker like Tracking (trk, tk), etc... even pixel (pix, px) might be a viable alternative.

Expert from Email Geeks explains that for SFMC, unless you change it, they use click.sub.domain.com (and image, view, and a few others). Mailbox Providers are more interested in whether people are engaging (and if the final destination of the click is a spammy site or not) and humans aren't looking at the URLs generally since they're almost always a 40+ character hash anyway.

What the documentation says
5Technical articles

Technical documentation from Google, SparkPost, Microsoft, and AWS indicates that using 'tracker' in a subdomain is unlikely to directly cause emails to be marked as spam. Subdomains are treated as separate entities for reputation. The primary factor influencing deliverability is the reputation of the subdomain itself and adherence to email sending best practices. RFCs do not address naming conventions.

Key findings

  • Subdomains are separate: Subdomains have their own reputation, independent of the main domain.
  • Tracker OK technically: Using 'tracker' in a subdomain is not inherently a technical issue.
  • Reputation is key: The subdomain's reputation and sending practices are the primary determinants of deliverability.
  • Best practices matter: Following email sending best practices is crucial for maintaining a good reputation.
  • RFCs are irrelevant: RFCs focus on technical standards, not marketing or naming conventions.

Key considerations

  • Subdomain reputation: Monitor and maintain a good sending reputation on the tracking subdomain.
  • Best practices: Implement proper authentication (SPF, DKIM, DMARC) and avoid spam triggers.
  • Sending practices: Ensure email content is relevant and engaging to avoid spam complaints.
  • Technical setup: Correctly configure DNS records for the subdomain (MX, A records, etc.).
  • Monitoring: Monitor deliverability metrics and adjust practices as needed.
