What happens if there are network outages or server downtime while calling QUEUEMAIL.DEV API?

The solution is to implement a local queue to store failed emails when QUEUEMAIL.DEV does not respond.

Hardy client example shows you how to implement this local queue.

How many requests can I do?

QUEUEMAIL.DEV servers implement protections against brute force or DDoS attacks so it is a good idea to space out your API requests by at least 1 second. No problem if you make more requests in 1 second, the protection system evaluates other parameters to find out if it is an attack or a normal use API but in any case we recommend that you always implement a robust sending with local queue so that if at any moment your source IP is temporarily banned, local queue will take care to retry pending emails.
