How to land email in inbox ?

if you bought the list that means the people on the list did not give you permission to send them email, right? so to not spam them that would mean you need to send them a request to opt in to your list first.

As dvduval stated; buying a list does not necessarily give you permission to email them. Some will argue that 'if' the subscribers agreed to 'receive information for/from third party offer and providers'... this is ok. (*I am not a legal expert, so I would consult a legal professional)

Once you determine 'if' you can legally solicit that list with your future offerings, you'll need an autoresponder from AWeber, GetResponse, or Constant Contact. I believe they allow importing existing email lists, but not sure about that 'if' you bought the list. Again, seek legal advice.

While it may appear easier than building your own list, and through targeted marketing, you need to remember... if someone sold you this list, the likelihood is, it wasn't worth much -or- they would keep it, and market to that group themselves.

How many people bought the same list?

How targeted is that list?

You see, you cannot know, only the person who sold you the list knows the true value of that list, and if it had any value, WHY sell it?

I'd get a refund, if possible.

Also, I would use it as a learning experience. I made similar mistakes 'buying bulk traffic' and learned the hard way when I first started out, so you're not alone.

Get an autoresponder, set up a clean and simple opt-in offering something relative to an existing niche audience, collect targeted prospects, send them to offers, and follow-up with emails, as MOST do not BUY anything the first time they see an offer.

Using a reputable Email service provider like Getresponse or Aweber will help to ensure your emails do not get listed in Junk mail. Both have tools within them to check your email and determine your spam score

Importing your list to these services may prove difficult as you have bought the list.. So you may need to prove to them that you are allowed to send to the subscribers when you import

You're finished before you even start. Don't go around buying lists. You need to go out and attract targeted leads for an offer. There is no fast track in internet marketing (unless you have $1 million to invest). Approach opt-in email in the same way that the pro's teach about here on the Warrior Forum.
