10 Proven Ways to Increase Your Email Open Rates

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.
