Do we get any Acknowledgement by post after applying online Tier 1 Entrepreneur to ILR

Hi,

I have tier 1 entreprenuer visa BRP Expiring on 02/03/2019. I qualified for ILR in march 2018 so i applied for ILR online for myself and 4 dependents wife and 2 daughters under 18 applied on same form with me and my 3rd daughter is 21 years old she applied separately using child over 18 form we all applied on same date. We all applied on 13th July and paid fees online. Got Homeoffice reference number , payment ref number and BRP letter online. We got our BRP done on 15th Jully and send all supporting documents along with our passports and BRP cards to home office by DHL courier today 17th July.

My question is since we already got payment ref number and Home office case ref number plus BRP letters online as soon as we paid fees by credit card does home office send us any confirmation by post acknowledging our application and confirming receipt of supporting documents. Has anyone who applied online got any postal acknowledgement.

Anyone who applied online ? Do you get any acknowledgement of receipt of documents , passports and BRP etc by post or by email ?
