Delayed deliveries can occur for several reasons, including:
Server Issues: Sometimes, the email marketing service provider's server may experience technical issues, causing delays in email delivery. ISP Throttling: Internet Service Providers (ISPs) may limit the number of emails that can be sent in a given time period to prevent spam, resulting in delays. High Volume of Emails: Sending a large volume of emails simultaneously can cause congestion and delays. Spam Filters: Emails may get caught in spam filters, delaying their receipt by the intended recipient. Recipient's Email Server: The recipient's email server may also experience issues, causing delays in receiving emails.
