Dear
Having had the pleasure of mailing you [name of magazine] every month for
the past three years, we were wondering if perhaps you haven't realized that
your subscription ran out in [month]
We mailed you our [month] issue and have not yet removed your name from our
subscriber's list inasmuch as we felt that you may be unaware that it is time
for your renewal.
We have enclosed our renewal subscription card for you which provides for
12 issues of [name of magazine] at the low price of $ per issue, or $ less than
the newsstand price. As you can see, this represents a substantial savings.
We are looking forward to hearing from you soon.
