Snail Mail Only For the UK Well-Heeled?

From Monday, a First Class postage stamp goes up to 95p (an almost 12% increase). The Second Class stamp goes up to 68p (https://www.theguardian.com/business/2022/apr/04/price-of-a-first-class-stamp-goes-up-by-10p-to-95p-in-uk). We now seem an awfully long way from the introduction of the first 'Penny Black' stamp in 1840. It's appreciated that costs are rising for the Post Office (perhaps partially in relation to the massive compensation they will have to give to people falsely accused/imprisoned for accounting frauds in their sub-post offices?). Many people are now increasingly using electronic communications. Almost £1 for sending a card or a letter seems, however, to clearly signal the end of 'snail mail' for many folk.
