HELP: How long does it take to deliver a message?
Your message will typically be delivered to most Subscribers within an hour.
The number of Subscribers on your List and current traffic conditions at Mail-List.com can affect delivery times.
If a Subscriber's ISP mail server is temporarily off-line, delivery attempts will be repeated for 3 days. If the message is still undeliverable, that message counts as a bounce (IE rejected email).
