I'm talking with the owner of a local book store about building her website. She wants to be able to send out mass mailings to a list of people who have signed up for such.

Would you recommend something we can use that she can access through her PC while leaving the maintenance of the website in my hands?

Thanks,
Bill

I ran into this with two websites that I built. It really depends on the technical capabilities of the end user. Oh, and the time they have to learn new things.
These two sites are using email marketing companies. Constant contact for one, Mail Chimp for the other. They are very similar. Constant contact has been around longer. Look them up on the web. There are other companies, I have experience with these two and they work fine for my customers.
