The huge advantage of email over social media is that prospects and customers are more likely to see an email than social media. Just posting something doesn't mean that everyone you want to see your message will see it. Your post might not even show up in your targets' social media streams. However, an email will sit in the inbox until it's read (or deleted).
Most popular email marketing services offer functionality that strikes a recipient from a list once a certain number of emails to a specific recipient ‘bounced’ back as undeliverable. Don’t be overeager to remove a subscriber, though; there are valid reasons why an email cannot be delivered. Consider only removing such a subscriber after four or five “bounces”.
A disadvantage of digital advertising is the large amount of competing goods and services that are also using the same digital marketing strategies. For example, when someone searches for a specific product from a specific company online, if a similar company uses targeted advertising online then they can appear on the customer's home page, allowing the customer to look at alternative options for a cheaper price or better quality of the same product or a quicker way of finding what they want online. https://irp-cdn.multiscreensite.com/9dbac298/dms3rep/multi/stock-vector-email-marketing-concept-vector-illustration-flat-style-254975962.jpg
