Poor targeting: The email was sent to the wrong segment

[moumitaakter4407]

Definition: The percentage of recipients who clicked the unsubscribe link in your email and confirmed their opt-out.
Calculation: (Number of Unsubscribes / Number of Successfully Delivered Emails) * 100
Reporting Frequency: Include this in every campaign-specific report and your monthly/quarterly aggregated reports.
What to look for:
Spikes: A sudden increase in unsubscribe rates for a particular campaign might indicate:
Irrelevant content: The message didn't match subscriber expectations or was off-topi
Too frequent sending: You're overwhelming your audience.
Confusing CTA/Offer: Recipients felt misled after opening.
Consistent High Rates: If your unsubscribe rate is iran email list consistently above industry benchmarks (typically 0.1% to 0.5% is considered healthy, though it varies), it signals a broader issue with your list quality, content strategy, or overall email program.
Visualization: Line graphs to show trends over time, or bar charts comparing unsubscribe rates across different campaign types or audience segments.
Spam Complaint Rate:

Definition: The percentage of recipients who marked your email as "spam" or "junk" via their email client (e.g., Gmail, Outlook). This is a more severe signal to Internet Service Providers (ISPs) than an unsubscribe.
Calculation: (Number of Spam Complaints / Number of Successfully Delivered Emails) * 100
Reporting Frequency: This should be monitored very closely, ideally in real-time if your ESP provides it, and definitely included in all regular reports.
What to look for:
Any Complaints: Even a small number of complaints is a red flag. ISPs pay close attention to this.
Thresholds: Most ISPs have internal thresholds (e.g., 0.1% or lower) for spam complaints. Exceeding these can severely damage your sender reputation, leading to emails landing in spam folders or being blocked entirely.
Reasons: Complaints often arise from:
Sending to purchased/old lists: Recipients didn't opt-in or forgot they did.
Deceptive subject lines: Promising one thing and delivering another.
Lack of clear unsubscribe option: Forcing recipients to mark as spam.
Poor content quality/relevance: Subscribers simply don't want your emails.
Visualization: Clear, prominent display of this metric, often with a warning if it approaches critical thresholds. Trend lines are crucial to show if the rate is improving or worsening.
