The subject of an email can be similar to its title. This is the second piece of information visible to recipients, after the sender's name. Its purpose is above all to inform about the content and to encourage readers to open the email. The subject of an email can, for example, inform of a special offer, highlight the novelties of your brand or even warn of new content. It must be thought out and cared for so that it is at the same time intriguing, attractive and precise.
