… have added 15 new people to my newsletter subscriber list (and it’s only 1pm).

Someone published something I wrote in her organization’s newsletter and when it came out today, many of her readers clicked over and signed up for mine.

One of the most effective ways to grow your list is to offer your content (for free) to other people/organizations who serve the same market.

They benefit from the content you provide; you benefit from the extra exposure.

No, sorry, there’s no downside to doing this (I’ll try and think of one).
