Email newsletters provide a line of communications with your audiences and provide a 40-40x return return on investments. This is a good way to grow your newsletter list and maintain a 50% open rate.

• Getting new subscribers: Use pop-ups that are relevant and only to high-intent readers on your site. Provide proof of why they should subscribe to your newsletter with sample content. Make your welcome email stand out and front-load the first issue with your best content.

• Keeping subscribers: To keep your subscribers wanting more, send fewer emails. Sprinkle in humor and interesting links to turn your newsletter into a habit.

• Promoting your newsletter: Use exclusivity and offers to hook your social media followers into subscribing to your newsletter. Ask your subscribers to refer your newsletter to others to grow your subscriber base.
