hi,

i've some email database over 20k or so. would like to get suggestions how can i use them, few month back i've mailed from same domain for whom content i mailed. my host warn me that he recieves some complaints of the same.

I immediately stopped mailing.

Now seeking suggestions what to do so that domain didn't get blacklisted.

one idea could be using another domain in different host. but i am afraid i will still get warning and that domain value will go down.

Seeking your suggestions for the same... I mean Legal and Best method

Thanks
