Mastering the Subject Line
Your open rate is the gatekeeper of your success. If people don't open your emails, your content doesn't matter.
1. Personalized Subject Lines
Using the recipient's name or referring to a specific recent event can increase open rates by up to 50%.
2. The 'Curiosity Gap'
Write subject lines that tease information without giving it all away. Force the click.
3. Optimize for Mobile
Over 60% of emails are opened on mobile devices. Keep your subject lines under 40 characters to avoid being cut off.
