Is it ok to set up list and invite my more than 1000 yahoogroups members ?
Will it be considered spamming ? They actually have to opt-in, that's why I reinvite them to join.
Need 3 bonus domains ? Check on this link.
Knock yourself out. If they're already in Yahoogroups, you can send a link to the signup page, or try the discussion list admin feature to add invites.
Thanks for the confirmation. Indeed, I will try to invite them thru discussion list forum.
