You can also control who can comment on your Instagram posts if you want to take it a step further.
Almost every notification Instagram sends is pointless and you're wasting your time if you turn them on. Instagram typically sends notifications about ads, product announcements, trending locations, etc. The only notifications worth turning on are:
You can access these categories in the From Instagram section of the Notifications tab . You can always experiment to see if there are any notifications you want to enable, but on a personal level, most of them are pointless.
Many people like to see account suggestions within the Instagram app, but on their own. They don't like getting notifications because they won't just go into the app and follow an account.
You can turn this notification off by going to Following and followers > Account suggestions > Off . You can also remove Instagram follow suggestions from your feed, but that's not a big deal.
