Overlinking can create several issues for both the sender and the recipient. For starters, emails with too many links often get flagged by spam filters, reducing the chances of your email reaching the recipient's inbox. Additionally, a cluttered email can overwhelm the reader, causing them to miss essential information or abandon the email altogether. Lastly, overlinking can dilute the effectiveness of your call-to-action (CTA), as too many options can confuse the reader.
