learned that clean water initiatives were supported by the complimentary eCard I mailed to my mother.
I didn't have time to post anything, so I sent my mother a birthday card. It was completed in about two minutes and is free.
I then actually read the description of the platform. Each card that is sent helps fund clean water initiatives in Africa. I don't have to pay for it or take any more steps; it's just a side effect of utilizing it.
I've been purchasing physical cards for years, spending £3–4 on items that are recycled after a week on the shelf. This was free, came right away, and did something.
Finding a store, purchasing a card, remembering a stamp, and reaching a postbox shouldn't be the bar for mailing a card.
