I wonder if it has to do with the destination too though (albeit not
entirely either, since as you wrote it used to work fine for you).
Some combination of sendgrid and the destination then.

Here is a worse example, a delay of 2 hours and 40 minutes:

Just an example of one notification with a small delay. Here you see a 
delay of 6 minutes (note the different timezone, CEST==UTC+2).
