"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Leading to the correct answer but I do not know an algorithm to find provider for every phone number

My problem is I am in contact with many foreign people who visit united states and their phone number does not work. So they sometimes use whatsapp given an internet connection

another is sending sms

so that is 3 total.

what are other ways to contact.
especially because owner of phone number may have phone turned off or disconnected or bill not paid
Trent SmithCommented:
If a phone is off or the bill isn't paid then sending a message to the phone won't work.  What are you trying to accomplish?

What you are looking for is called a reverse append.  You will need to contact a reputable data company.   Some options could be,, to name a few.

If you want an address file to send snail mail, that would be the easiest and probably your best option. I would send a big giant post card.

Your other option is to send an email. However, when you do a reverse append where you supply phone numbers, the data company will not give you back an email list. Instead, they will send out an email on your behalf.

Sending out mass unsolicited email like this is probably going to have a very low open and action rate.  Let's say you have 100,000 phone numbers.  Your match rate may be 70,000.  You will pay two fees, one for processing and one per match.  

Now you send out 70,000 emails to people that do not recognize you  and the only reason they are getting an email is because of some other linked partnership they sign up and forgot about.  When you send out 70,000 emails,  lets say 50% make it to the inbox.  We are now down to 35,000.  Of those that make it to the inbox, 10% get opened. Now we are at 3,500.  Of the emails that get opened,  3% take action and go to your site.  Now we are at 105.  Let's assume you have a fantastic offer on your site and 50% of those people call in or ask to be contacted.  Now you are at 52. However, I think that will be high and you will probably be at 25.  Now it is up to you to sell somebody something. Again, assume you have a very high closing rate and you sell 60% of those that you contact.  That puts you at about 15 to 25 sales.

If you have a very high profit margin, that may work. Now imagine if you didn't have 100,000 phone numbers and only 10,000.  You would be lucky to get 1 or 2 sales.

My point is, the metrics are not there to send an email to people that you do not already  have a relationship with.  You are much better off sending an enticing big post card via snail mail.

If you did have a relationship with this group, you would already have their email account.  I would look to inbound and online marketing rather than go through what you are trying to do. If the market is big enough and your potential profits are in line, you will do better in the long run.
