First, There You Are
Wherever you go, there you are — surrounded by the common plantain.
Native to Eurasia, this humble plant has spread far and wide because its seeds cling to anything passing by — shoes, paws, tires, even trouser legs — especially when wet. Thanks to that hitchhiking prowess, plantain has made itself at home almost everywhere.
Wouldn’t it be handy to have something just as “sticky” for your inbox — so you can pin a thought or reminder that travels with a message, no matter where you move it? In Fastmail, you can do exactly that without even dampening your fingers:
