It’s placed there by the GM of the postboxes:

SingPost will paste the orange “No Admail” sticker on your letterbox and you’ll (hopefully) not see any more ads in it.

It Was Actually A Hidden Secret

So, you’re thinking: wait, that’s so well-hidden. How the heck did anyone find it?

Well, the starting point of this hidden function coming to light might’ve been back in 2016.

Back then, CNA ran a story on SingPost:

S’poreans Welcome Ad Mails Because Only 0.8% of 1.2m People Opted Out From Service

It was said that SingPost allows residents to opt-out of receiving advertising mails from the postal service.

And if they had opted out, they would have an orange “No Admail” sticker pasted on their letterbox.

SingPost personnel, once they see this, will not distribute any flyers to said letterboxes.

Unfortunately, Singaporeans back then didn’t believe in SingPost’s claims.


Basically, they think that people not knowing about the opt-out service doesn’t mean they welcome junk mails.

And with that, the internet got cracking and the secret “opt-out” service was soon discovered and publicised.

Should You Opt-Out?

So, here’s the thing: should you opt-out of the service?

That depends.

How irritated are you with receiving junk mails? As an HDB resident for nearly my entire life, I’ll say that receiving junk mails or not doesn’t make a difference.


In fact, I get my best deals (read: KFC coupons) from said advertising mailers sometimes. But that’s just me.

And don’t worry about regretting your decision if you’ve opt-out of the service.

You can always write in to revoke the “No Admail” status of your letterbox.

The enquiry form (read: the place to opt-out) can be found here.
