Here is a little used technique you can implement to build your mailing list for no additional cost. I call it “using subscribers to make subscribers” like much in the context of “using money to make money”.
This simple list building formula can be summed up in two words: ad swap.
Generally, you trade advertisements with other eZine publishers, preferably of the same mailing list size or bigger. You broadcast the eZine publisher’s advertisement to your mailing list while the eZine publisher endorses your ad to his list. Yes, you are actually cross endorsing or cross promoting each others offer to each of your mailing list.
