常见问题
What are spam trigger words?+
Words like "Free", "Guarantee", "Urgent", or excessive use of dollar signs and ALL CAPS often trigger email providers (like Gmail or Outlook) to route your hard work immediately into the Promotions tab or Spam folder. Always aim for conversational, human text.
Why does length matter?+
Over 60% of all emails are first read on mobile devices. If an email subject line exceeds 50-60 characters, email clients will truncate it with an ellipsis (...), which generally lowers click-through and open rates.
