💡 Why Subject Lines Matter for Deliverability
A good subject line not only encourages an open, but it also signals a quality sender to the mailbox provider (like Gmail or Outlook). Subject lines that contain **all caps**, **excessive punctuation**, or **spam trigger words** can instantly lower your sender score and land your email in the spam folder, even if your technical setup (SPF/DKIM/DMARC) is perfect. Always aim for **personal**, **short**, and **value-driven** subject lines.
