Disclaimer: This is _not_ Government policy, I do _not_ work for the NHS, and I am _not_ an expert. This is just me applying common sense to the various bits of advice we've been getting over the past weeks. If you are an expert and think this is rubbish or dangerous, let me know and I'll remove it. For now here is Mabel's Unofficial Post Safety Protocol.
First thing to remember: Letters and parcels will not cough or sneeze on you. Even if the virus is on the envelope or packaging, it will not infect you unless you touch it and then touch your face _without washing your hands in between_.
Second thing to remember: Unless Royal Mail/the courier has been extremely quick, no-one will have touched what's inside the letter/parcel for at least 15 hours, and in most cases considerably more.
So pick up the post from the doormat and take it straight to a place where you can put it on an easy-to-clean surface (e.g. in a utility room). Open the letter/parcel, put the envelope/packaging down on the easy-to-clean surface but do _not_ put the contents down – take it to another, clean surface, preferably not plastic or stainless steel. (I realise there is a risk of cross-contamination in this step, but I would think it is very small; if possible, you can shake the contents from the opened packaging onto the clean surface – this would eliminate the risk altogether)
Get rid of all the envelopes/packaging, clean the surface they've been on and wash your hands thoroughly. If you want to make doubly sure it's safe, leave the post for an hour on the not-plastic-not-stainless-steel surface before picking it up. Then enjoy your letters, cards, purchases, presents and other encouraging items
