Finding companies by their Email Delivery Service stack

The count beside each tool is the number of ranked websites in Hunter's index where that tool was detected. It is a floor, not a vendor's customer list.

A detection describes what a site runs today, and a tag left in place after a team stopped paying still counts — so treat one detection as a lead to check. Two tools from this page on the same domain is the more interesting signal: a migration, a trial, or an old tag nobody removed. All three mean the decision is open.

Every technology page here lists the ranked websites running that tool. Discover takes the same signal as a filter and adds company size, industry and country on top, so the list narrows to the accounts you actually sell to.

Email Delivery Service technology FAQs

Hunter keeps an index of websites and records the technologies detected on each one. Every page in this section is built from that index and rebuilt daily.

Once a day. A page whose numbers did not move keeps its previous date, so the sitemap does not claim a change that did not happen.

Yes. Open the tool's page to see the websites it was detected on, then use Discover to filter the same signal by company size, industry and country before you export the contacts.

A technology earns a page once Hunter has detected it on enough websites for the page to say something useful. Tools below that line are still detected and still searchable — they just get no page of their own.
