+I now offer paid plans for ntfy.sh if you don't want to self-host, or you want to support the development of ntfy. You can **buy a plan for as low as $3.33/month** (if you use promo code `MYTOPIC`, limited time only). You can also donate via [GitHub Sponsors](https://github.com/sponsors/binwiederhier),
+and [Liberapay](https://liberapay.com/ntfy). I would be very humbled by your sponsorship. ❤️
