    So ive been doing more TLD mailing as of late and wile doing data QA, I noticed a pattern in many bad emails I was getting.

    They were emails that looked like this:


    [email protected]
    [email protected]
    [email protected]


    So what I did was jumped in excel and made a few list where I did this

    @1hotmail.com
    @2hotmail.com
    @3hotmail.com
    .
    .
    .
    .
    @10000hotmail.com


    so I created 10000 addresses for each of the major TLD domains and added them to my suppression file.

    I have already noticed this trick has caught many bad emails and improved my bounce rate slightly.

    Hope it helps you guys too!

    Just set your filter program or text editor to save or remove @yahoo,@aol,@hotmail etc. Guaranteed clean domains - been doing that for years.

    Well the issue I was having, was that on send safe list manager, when I try to filter out the good domains, like yahoo.com, aol.com etc..

    It would still include the emails @101yahoo.com

    caus it included yahoo.com in the domain...

    I had the same problem, but if you put the @ before yahoo.com - @yahoo it will look for only @yahoo.com and not all yahoo.coms

    I usually pull a unique list of domains from the data and import them into a system to resolve their mail servers.. If the domains do not exist they get removed from the data. Another helpful program will return addresses that share 80% of the same characters. I've found quite a mass of seeds and traps this way. For anyone interested in the string similarity program, I've attached the source code (c#) and compiled binary..

    The easiest way to deal with this is to do what SG said, which is what I told him to do, which is why he's telling you to do it...because it works. Blacklists are a waste of time. Create a whitelist of known "safe" domains to mail to and fire away. It's a lot less data to worry about and when you add new data you don't need to pick out the bad domains; just exclude them from your list by not importing them.
