A friend has gathered 3500 names and e-mail addresses of customers but didn't capture the info in a mailing list program.  He wants to set up an announcement-only mailing list for those people who have indicated interest in his business.

 

What mailing list software would you suggest in 2010 for this purpose?  Hosted like Listserv ($$$) or Yahoo Groups (free) ?

 

Or a desktop solution?  Suggestions?

 

My guess is the number of subscribers could double or triple over time...

 

Thanks,
