Several methods can be employed to clean your email list:
1. Verification Tools: Use email verification tools to check the validity of email addresses. These tools can identify syntax errors, domain issues, and inactive addresses. 2. Segmentation: Segment your list based on engagement levels. Remove or re-engage subscribers who haven't interacted with your emails in a specified period. 3. Manual Review: Occasionally, manually review your list to ensure that the data is accurate and up-to-date. 4. Double Opt-In: Implement a double opt-in process to confirm that subscribers genuinely want to receive your emails.
