Several factors can contribute to desensitization:
Frequency: Sending too many emails in a short period can overwhelm recipients, leading them to ignore, delete, or unsubscribe. Repetitiveness: Repeatedly sending similar content can cause recipients to lose interest. Irrelevant Content: Emails that aren't tailored to the recipient's interests or needs will likely be disregarded. Overexposure: When recipients receive numerous emails from various sources, each individual email's impact may be diluted.
