- Email marketing becomes weaker when messages do not reach the customer’s main inbox.
- Spam filters, promotional tabs, blocked senders, and poor sender reputation can move emails away from normal inbox visibility.
- Low deliverability reduces opens because customers may never see the message in the first place.
- Some campaigns are filtered before the customer ever sees the subject line.
- Promotional folders often keep emails away from normal daily attention.
- Sender reputation becomes important when mailbox providers decide where messages should go.
- A campaign may look unsuccessful even when the offer itself was useful.
