A few newsletters ago, I asked for your help. Could we, together, vanquish Canada?

Could we add more new sign-ups to the Australia Letter than my colleague, Ian Austen, could add to his newsletter, the Canada Letter?

Since Canada had more than double our subscriber base to pull from, it was an epic challenge. Not quite like trying to reach the third round of the Australian Open when you’re only 15 years old. But sort of.

And you did it.

Marta Kostyuk became the youngest woman to reach the third round of a Grand Slam in 21 years this week; and as of Thursday night, 1,921 people signed up for the Australia Letter since my plea at the end of November, compared to 1,334 for the Canada Letter.
