There are several reasons for slow email processing:
Server Overload: When email servers are overloaded, they may experience delays in processing and delivering emails. Spam Filters: Emails can be delayed if they are flagged by spam filters, which take time to scrutinize the content. Queue Management: Email service providers often manage queues, which can slow down the processing time, especially during peak hours. Technical Issues: Network issues, server maintenance, and other technical problems can also contribute to delays.
