Disposable email addresses are really a pain for website owners and hence it becomes super important to detect temporary emails in real time. Disposable emails ceases to exist in few minutes or hours depending on the service provider, which means as a website owner all the followup email campaigns you organize for this email address would bounce. Obviously one email bouncing wouldn't probably get you into trouble but this does accrue over time and might adversely affect your sender reputation.
At Antideo, we ensure that you are able to validate email addresses in real time to block out disposable emails and force the visitor to enter their real email address.
