    • Avoid using excessive capitalization, exclamation marks, or misleading subject lines.
    • Regularly monitor your sender reputation and maintain a clean mailing list by removing inactive or unengaged subscribers.
    • Authenticate your domain with SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication Reporting & Conformance) records.

    • Uninteresting subject lines: Craft compelling subject lines that pique curiosity and clearly convey value.
    • Poor timing: Experiment with different send times to find when your audience is most likely to engage.
