High Percentage of Unengaged Subscribers

[hrsibar4405]

Definition: Subscribers who haven't opened or clicked an email in a significant period (e.g., 6-12 months).
Why they're a problem: Drag down engagement metrics, waste sending resources, contribute to deliverability issues by signalling disinterest to ISPs.
Segmentation: Importance of identifying and segmenting these users.
B. Numerous Typos and Formatting Errors in Email Addresses:
Source: Manual entry, poor form validation, data migration issues.
Impact: Hard bounces, wasted sending.
Identification: Manual review, list cleaning tools.
C. Presence of Role-Based Email italy email list Addresses (e.g., sales@, info@, admin@):
Why they're problematic: Often shared, not personal, low engagement, higher chance of being spam traps.
Caution: Not all are bad, but a high percentage can indicate a lack of true opt-in.
D. Duplicate Email Addresses:
Cause: Multiple sign-ups, data import errors.
Impact: Annoying to subscribers, inaccurate metrics, wasted resources.
Solution: Deduplication during list cleaning.
E. Old or Stale Data:
Natural decay: Explain that email lists naturally decay over time (20-30% annually).
Signs of staleness:
Lack of recent activity from a large segment.
Emails collected years ago with no recent engagement.
Emails from defunct companies or roles.
IV. Qualitative and Acquisition-Related Signs (approx. 600 words)

A. Lack of Double Opt-in (DOI) Process:
Definition: Explain single vs. double opt-in.
Why DOI is superior for list quality: Confirms intent, reduces typos, prevents spam traps, builds stronger sender reputation.
Sign of a dirty list: A large list built solely on single opt-in, especially if engagement is low.
B. Suspicious List Acquisition Methods:
Bought/Rented Lists: The cardinal sin of email marketing. Explain why it's harmful (no permission, spam complaints, blacklisting).
