I need some advice about subscribers. I run a hosting website and have about 80 paying members so far. Could I send these guys "upgrade" emails as they're already "customers" or is still considered spam.
Places like Amazon and eBay are always sending me emails to buy this/that.
Too be honest I'm not about to start sending my members upgrade emails but I just want to know where I stand with regards to how I can communicate with them.
Also, if I start to use Aweber, MailChimp or Getresponse can I download a list of my subscribers names/email or do these belong to the list manager? Have you ever tried to migrate subscribers to a different list manager?
Thanks for your help,
