Spam can have negative consequences on your brand and can affect your online reputation, so it is important to take certain measures. One of the initial measures to take into account is to create a high-quality subscriber list because it will reduce the chances of your emails being marked as spam. Additionally, you should pay attention to personalizing your emails to increase the chances of subscribers opening and taking action on them. It's also essential to comply with spam rules, which include adding an easily visible unsubscribe option in every email, avoiding the use of words and phrases associated with spam, and respecting privacy and data protection laws. Using a reliable email marketing service provider is important to avoid major problems that require an expert.
