What is Email List Hygiene?
Email list hygiene refers to the process of maintaining and managing your email subscriber list to ensure it remains clean, updated, and effective. This involves regularly removing invalid, inactive, and unengaged email addresses from your database to improve your email deliverability and overall marketing performance.
Deliverability: A clean list ensures that your emails are more likely to reach the inbox rather than being marked as spam.
Engagement: Sending emails to active subscribers increases engagement rates like open and click-through rates.
Reputation: A high-quality list helps maintain a good sender reputation with ISPs (Internet Service Providers).
Cost-Effectiveness: Many email marketing platforms charge based on the number of subscribers. Removing inactive addresses can save costs.
How Often Should You Clean Your Email List?
The frequency of cleaning your email list depends on the size of your list and the frequency of your email campaigns. However, a general rule of thumb is to perform list hygiene every 3 to 6 months. If you send emails daily or weekly, more frequent cleaning may be necessary.
High
Bounce Rates: Frequent hard bounces indicate invalid email addresses.
Low
Open Rates: A significant drop in open rates suggests disengaged subscribers.
High
Unsubscribe Rates: A high number of unsubscribes could mean your emails are not relevant to your audience.
Spam Complaints: If subscribers are marking your emails as spam, it's a sign of poor list quality.
Validate Email Addresses: Use email verification tools to validate new and existing addresses.
Remove Hard Bounces: Immediately remove email addresses that result in hard bounces.
Segment Inactive Subscribers: Identify and segment subscribers who haven't engaged with your emails in a specified period.
Re-Engagement Campaigns: Send targeted emails to inactive subscribers to win them back. If they remain unresponsive, consider removing them.
Monitor Engagement Metrics: Regularly track open rates, click-through rates, and other engagement metrics to identify trends and take action.
