Please give more than just a flow because that forces people to load it and, quite frankly, many of us don't have time to do that for every question.

Also your flow is not importable. Please read [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

beat me to it, its like there is a parts of a flow pasted several times with the same screenshot pasted into the middle and at the end. All wrapped in ````` code markers `````

this is the screen shots I pulled out of the code block...

 ![Screenshot from 2020-02-10 23-10-32](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/8/387c271c33847c9cc27cf0e09c1b22a0ebab2a02.png)

it looks like he is looping through an array and sending messages delayed by 4s.

@abhishekjaiswalraw I would say, no (IMO), not the ideal way to do that. You'd be better sending the array of items in one go via a delay node set to "rate limit 1msg / 4s"
