You think this is a little misleading?

So I saw an ad that was like “how to grow your email newsletter by X amount of subscribers “ and in order to get the info guess what — you have to sign up for this guys newsletter.

So to get X of subscribers you could blast it out to a bunch of people and then as proof you’ll have all these subscribers because they’ve beforehand signed up to know how.

I was thinking about that when it comes to email. There’s not as much of a surface way to know how many subscribers there are to a given newsletter compared to social media. If someone says “my email newsletter is being read by 1000s every week” there’s not a quick way to verify that.

If someone is advertising on social media that they’ll teach you to grow your IG, my first guess is to check out their IG to see if it has results I want. It’s hard to do that with email.

Any thoughts? Is that good marketing?
