Combining online and offline marketing strategies are the best way to get maximum reach from your business. That said, email marketing tends to be pushed to the back of the queue compared to social media marketing and business brochures for example.
Email marketing can be an effective tool if done correctly. Once you have a growing list of subscribers, sending out regular emails is definitely an effective marketing strategy, but only once the email is opened. Improving your open rate can be achieved by creating curiosity with your email title, making the recipient want to know more.
Once the email is opened you want to include a good amount of visuals complimented with to the point written content to drive the point clearly. A great way to break a chunky text box up is by using bullet points with simple short points. Always provide easy links to your website and relevant contact information for the readers.
