Imagine a scenario. You are about to start researching for a trip to a nearby country. You need to know details into everything, from the flight fares, hotels to the places you can visit. Just then, you receive an email that talks about offers, details into the trip to that same place, and other things. You obviously click that email to know what it has to offer.
Email marketing is all about sending the right message at the right time to the right person at the right place. You can never miss out on the right opportunity to convert. However, sending the right type of email also makes a lot of difference. There are the promotional emails, and the transactional or behavior triggered emails that you might have to send, depending on the stage of the sales funnel they are in, and what the audience is looking for.
