How this service works
Free directory of email-security and MSP tools for small businesses. Free-tier notes are dated from each vendor page.
Output
Returns a JSON object with the checked email address, a verdict string (e.g. 'ok'), a boolean indicating whether the address is disposable, and a boolean indicating whether it is a role account (e.g. admin@, info@, support@).
Example use cases
Block fake signups at registration
“Before creating an account for the user who just signed up with temp9832@guerrillamail.com, check if that email is disposable so we can reject it.”
Clean email list before campaign
“I have a lead who gave me info@somebusiness.com — can you check if that's a role account or a legit personal email before I send them our outreach?”
Fraud screening for new orders
“A new order just came in from someone using a suspicious-looking email address, dropbox123@mailnull.com — can you verify if it's a throwaway address so I can flag the order for review?”
Technical details
Endpoint
GEThttps://api.mailsecuritytools.com/v1/email-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, low-cost ($0.01/call) check on individual email addresses to detect disposable or role-based addresses before user registration, list addition, or outreach. It is well-suited for real-time validation at the point of data entry rather than bulk batch processing.
Side effects
- Missing or malformed email parameter returns an error
- Email string exceeding 320 characters rejected
- Network timeout if upstream lookup service is slow
- Invalid email format may return an error or unexpected verdict
- Rate limiting if called in rapid succession
