Out of Interest - I have a question/s

Hi folks

I have a question for you, a multi pronged question really,
Those of you that know me know that I am reasonably fluent in the implementation of my below questions, however, and bear with me, I am asking you these questions, because yes I am going somewhere with this, and you may find what I have to offer as a positive for your directions. In which case humour me :)

I am interested to know

1. What mailing programs you use for your Mailing List
2. Does your Mailing Program meet all your Needs
3. How do you promote your mailing list
4. Do you create a Mailer Series
5. Is your Mailer Series engaging, successful and always expanding, How do you make it engaging
6. Is your Mailing subscription base increasing and by how much on a weekly or monthly basis
7. Do you allow your subscriber base to contribute to the Mailing List

That will do for now, I have many questions that will be presented to me by your responses and those we will address in the coming conversations

Have a great and productive day
