It is possible to build your mailing list for free using what I call “using subscribers to make subscribers”, which is the same as “using money to make money”.
It’s a simple formula that can be summed up with two words: ad swap.
Generally, you exchange advertisements with other eZine publishers, preferably of the same mailing list size or larger. You broadcast the eZine publisher’s advertisement to your mailing list while he endorses your ad to his list. The two of you are actually cross-promoting each other’s offers to your respective mailing lists.
The goal of your advertisement should be to sign up as many subscribers from the other eZine publisher’s list as possible.
As a result, your mailing list grows. The method does not require any money, so you can do it for free. And the return on subscribers? Infinite.
It is only necessary to do this with one eZine publisher at least once, since both his and your subscribers can now be followed up within your mailing list.
You can build a huge mailing list for free by swapping ads with as many eZines as possible.
