Server issues in email marketing can arise from a variety of sources. Some of the most common problems include:
Server downtime: When the email server is down, emails cannot be sent or received, causing delays and potential revenue loss. IP blacklisting: If your sending IP address is blacklisted, your emails may be marked as spam, reducing their deliverability. High bounce rates: Emails that bounce back due to invalid addresses or full inboxes can negatively impact your sender reputation. Throttling: Sending too many emails in a short period can trigger rate limits, causing delays in email delivery. DNS issues: Problems with Domain Name System (DNS) settings can lead to authentication failures and reduced deliverability.
