Emails not coming through on time

Question

We have some emails that are coming through a day or two later after the original date sent. Then other emails are coming through just fine.

Answer 1

Delayed email delivery can be caused by several factors. Here are some potential reasons for emails arriving late:

1. Server Responsiveness: The intended destination server may not be responsive, which is a common reason for delays.
2. Message Size: Large emails can take longer to process and deliver.
3. Service Latency: There may be latency in the email service that causes delays in delivery.
4. Filtering Services: Emails might be blocked or delayed by filtering services in place.

To troubleshoot, you can check the message trace tool to see if there are any pending or completed traces for the delayed emails. This can provide insights into where the delay might be occurring.
