Regularly clean your subscriber list to remove inactive or bounced email addresses. This ensures that your emails are sent to engaged recipients, improving your sender reputation and delivery rates.

Before sending out a mass email, send test emails to yourself or colleagues to check for any formatting issues, broken links, or rendering problems.

Analyze your data to determine the best time to send emails for maximum engagement. Consider time zones and recipient preferences.
