If when trying to signup your email has been flagged as invalid, mistyped or disposable it means Flatly's email bot has detected that your email is one of the following:

AcceptAll Email Domain (example:  anything-can-be-added-here@acme.com)
​Disposable (example:  Yopmail)
​Undeliverable (example:  notavalid.email@something.wrong or invalid&@edu.fov)

Flatly requires real email accounts associated with real human individuals to ensure that account-related correspondence and job notifications can function properly.

We recommend signing up with Google or Microsoft to simplify the signup process.
