It didn’t even take a full week.

For context: in 2011 it took Instagram three months to reach 1 million users.

Of course, there are far more people using the internet in 2022 than there were in 2011. That should not diminish how fast this growth is. Even though ChatGPT is free, it still requires email sign-ups to use it.

Getting a million email subscribers is a big deal — an email audience in the seven-figures could be the foundation for a multi-million dollar business these days.
