Links, Protocols & UTM Tracking
Configure link destinations, ensure valid security protocols, append UTM analytics parameters, and avoid spam triggers.
Key Takeaways
- Always use https:// protocols for all email links.
- Never use link shorteners (bit.ly, tinyurl) in marketing emails — they are heavily flagged by spam filters.
- Append standard UTM parameters (utm_source, utm_medium, utm_campaign) to track conversions in Google Analytics.
- All PostBrix links automatically include target="_blank" and rel="noopener noreferrer" for security.
Appending UTM Parameters#
To measure email campaign performance in your analytics tool:
code
text

newsletterorpostbrix - utm_medium:
email - utm_campaign: Name of the campaign (e.g.,
onboarding_flow) - utm_content: Identifies specific buttons or links clicked (e.g.,
header_logo,hero_cta)
Link Security Guidelines#
Spam filters evaluate email link reputations rigorously:
- Avoid Generic Link Shorteners: Services like Bitly, TinyURL, and Ow.ly are commonly abused by phishers and trigger automated spam quarantine.
- Match Anchor Text to Destination: Avoid displaying anchor text that looks like a URL (e.g.
www.bank.com) while pointing to a different domain (www.trackers.net), as spam filters categorize this as credential spoofing.
