SERVICES PROVIDED

 

Note: Not only do we CHECK for these issues, we provide 24/7 MONITORING of these as well....

 

Content Analysis Phrasing, trip words, blacklisted images and words, hex-encoded whitespace triggers, excess spacing, broken HTML, missing HTML tags, content balance, colors, div and css issues, off-site css issues, man-in-the-middle poisoning, page loading issues, web server excess spills, combination word/phrase triggers, waterfall blocks, carousel triggers, and much more

 

DNS Analysis (timing, response agreements, rDNS issues, blocks on DNS, blocks on rDNS, poisoned caches, fragmented cache responses, poisoned 3rd party data, blacklisted DKIM references, blacklisted SPF references, blocks on SPF data, blocks on DMARC pointers, cache laggards, foreign country DNS blocks, out-of-range settings, and more, including proprietary checks which ISP's have advised us are part of their filtering.

 

Blacklist Analysis 913 known blacklists (combination of IP and domain), 47 "sub-terranean lists" used by major ISPs for filtering, MSSS probes (for Microsoft analysis), Yahoo/AOL known blockfeeders, known Gmail content triggers, 9 third-party reputation beacon systems, and more lists as they are discovered [often weekly].

 

Whitelist Analysis 61 known locations examined, 14 whitelist detractor sites (feeds negative data to whitelists), IP and Domain probes into all ISP-based whitelists, content tests into all ISPs for behavior analysis, and several proprietary probes we issue to all ISPs for whitelist status determination.

 

Proprietary Analysis These are techniques we have proven to help us uncover "hard coded entries" made by blacklist owners, ISP's, and third parties. The blocks may be due the type of business you run, your political affiliation (yes, they secretly block because of that, too), outsiders "getting even" with you or one of your staff (common in the IT industry), disgruntled employees reporting false spam-related/abuse issues causing special blocks, etc. These are some of the most damaging blacklists your company can be on yet only a handful of people know where to look to find those type of entries.

 

YOU ARE IN GOOD HANDS HERE

 

More items will be listed on this page as we add them to our service. However, there are many techniques, services, and lists we uncover every week which may not be listed here but will be performed when we analyze your campaigns.

 

EXTRA ITEMS TO NOTE

 

Stuff our lawyers said to mention: ListWorker cannot provide you or your company any guarantees that we can help you fix any problems simply because we do not know your marketing history, the history of your network, or the history of your upstream network provider. Usage of our service does not provide any guarantees of any kind. We will do our absolute best to find the issues causing problems but we can't guarantee those issues can be fixed becuase we just don't know your history.
