There are several reasons for delivery delays in email marketing, including:
Server issues: Both sending and receiving servers might experience technical difficulties or high traffic. Email throttling: ISPs may limit the number of emails accepted from a particular sender in a given period. Spam filters: Emails might get stuck in spam filters, causing delays in delivery. Recipient server policies: Different email providers have varying policies that might delay email processing. Network congestion: High volumes of internet traffic can slow down email delivery.
