Why is my website blocked for mobile customers because my hosting provider is on a spam blocklist?
Site owners find out by accident that their IP sits on a blocklist because of everyone else on the same hosting network, and that some mobile carriers filter on it, with no alert, no appeal route and a paid whitelisting offer as the only exit.
Who has it: Owners of small web shops, SaaS products and agency sites on shared cloud hosting such as DigitalOcean who depend on customers reaching them from mobile networks and corporate filters.
Evidence
“I recently discovered by accident that our website was being blocked by Orange's security filters.”

Existing players
- Public blocklist lookup sites such as MXToolbox · Check an address on demand, but do not watch it, and they do not tell you which carriers or filters actually block your visitors.
- Paid whitelisting from the blocklist operator · The offer in the thread is a monthly fee for an address that did nothing wrong, which is the complaint.
- Uptime monitors · Test from data centres, so they report the site as up while customers on one mobile network see it blocked.
What they are missing
A monitor that checks your site's IP and mail server against the major blocklists, probes reachability from mobile and corporate networks in several countries, and alerts you the day a listing or a carrier block appears, with the exact appeal or workaround steps.
