If you are doing email marketing, your marketing will be successful only when there is conversion. Conversion will occur only when there are engagements. Therefore, you need to boost email engagement for better results. First and foremost, the receiver needs to open your email, a lot of people send emails to trash bin without opening it, you need to do something that will stop receivers from doing this so that you achieve high email open and conversion rates. This will happen only when you send emails to those genuinely interested in your offerings. THis means that you need to have people who genuinely subscribed to your emails. Many struggle with email marketing because they don't focus on their genuine subscribers or use compelling subject lines.
