Solution · Fake accounts and disposable emails
Block fake accounts and disposable emails at signup.
For any site with a signup: your stats, your email sends and your decisions rely on real people.
The problem
- 01
Disposable addresses (Yopmail, Mailinator…) created in seconds and abandoned right away.
- 02
Bots filling in your forms and skewing your acquisition stats.
- 03
Emails sent to dead addresses, damaging your sender reputation.
How Ksar solves it
Over 97,000 disposable domains
Lists updated automatically, plus detection of new services through their mail servers.
Addresses without a mail server
An address that cannot receive any email is blocked.
Suspicious patterns
Random strings and domains without a website are spotted and penalised.
