Domain Names Forum

World Wide Domains
List of Internet Domain Names

This is a shot in the dark, but does anybody know of a website or other resource that has a list of existing internet domain names, or failing that does anyone know of a tool availiable that can filter out non - existent e-mail addresses and mispelled e-mail addresses. These questions are an attempt to stop paying for e-mails being sent out to non existing addresses. Severel campaigns have continued to mail soft bounced addresses repeatedly that just turn into hard bounce addresses.

Any help would be hugely appreciated.

There are lots of products already on offer which can attempt to validate a list of email addresses, flagging potential bounces from an email list - they aren't 100% accurate but will normally flag all bad domains and a percentage of invalid names.

Having been in this position myself I'd suggest that if you really want to cut down on bounces then you need to look at how you're handling the lifecycle of the data...

Are the errors coming in at the data collection stage?

If they are then you might want to consider improving the validation on your data capture so that you can address common issues on the spot. Bear in mind the only way to really guarantee a valid email address is to email it at point of capture and get the user to confirm it via a clicked link.

Are the errors only coming to light during the course of the mailing?

Normally this is a data age or data quality issue, and outside of actively re-confirming details semi-regularly the best you can hope for is to work through the errors and bounces so that you can determine which contacts were unable to be emailed.

Over time flagging bad data has a really positive impact on cleaning up an email list, making future maintainance much easier.

If you use double opt-in (email a confirmation email with a unique link they have to click on to join) then you'll know that all the email addresses on your list were good at least once. That's one way to create a very clean list.

Of course it will lose addresses over time (people move ISPs, change jobs, mailboxes fill up, free email providers shut down etc.) but at least you're starting at the best possible point.

Beyond that, a search for "change of email address" on Google should help track down some of the companies that can provide list cleaning and verification services.

I recal seeing asite that had listing of domains 9in alphabetcial order, but it displayeed maybe 50 a page, so I don't think that would help you.

But as someone said there are software that can verfiy existance of domain or mail server. We use Groupmail with Email Inspector plugin for that purpose.
