I hope all emails can be sent out correctly. After sending one message, pause for a certain period of time instead of sending the next one immediately。
Hi Kevin ! Which email service do you use ? Do you know if you can do some throttling settings ? I know it usually improves the delivery (once all messages are sent) but it can sometimes improve the sendings. Let us know
@merefield is right indeed. In any way, dealing with your ESP settings would be a quick fix and wouldn’t replace an efficient queuing or buffering feature.
