Indisposable is an application that helps protect your community by blocking registrations that use disposable e-mail addresses.

Why are disposable e-mails bad?

Disposable e-mails are not inherently bad, but they should not be used for registering accounts on platforms such as IPS.

Foremost, they present a significant security risk for your members. These e-mail accounts are publicly available to anyone and everyone with no password required. That means if someone registers for your community with a disposable e-mail address, anyone else who also uses that disposable e-mail service can see this and could completely take over that persons account.

Second, disposable e-mails are commonly used for abusive purposes, as they make evading bans much easier. Instead of the user having to go through the lengthier sign-up process for a new e-mail account with GMail or so on, they can generate a new throwaway e-mail in seconds.

How is this different from just manually banning disposable e-mail domains?

Disposable e-mail services actively fight against people doing just this by registering cheap alias domains to tie to their service whenever one gets too much attention.

On our test community with roughly 100,000 unique members, we have logged over 1,000 unique disposable e-mail domains.

Trying to keep up and block these manually is not practical. That’s where Indisposable comes in.

Indisposable uses Kickbox’s industry leading e-mail validation services to instantly identify and reject disposable e-mail addresses, requiring no additional work on your end.


This application only validates e-mail domains. That means if a user registers with “john@example.com”, all we do is verify that “example.com” is a valid e-mail domain. Your members actual e-mail addresses are not collected or sent to any third-party, ever. Period.

Works so well you forget it's installed.  A must have in my book.  Temp email addresses are a real pain for admins.

A must have. IP bans are not feasible any more. This is a fantastic supplement.

Support - A+

Functionality - What's mentioned in description, it works. If you need enhancement, up to the coder but developer is always open for feedback and responsive and not like some, where you need to keep following up for feedback. 

Performance - A+

Awesome plugin. The dev put a lot of work into it and created a nice app that works exactly as advertised. It help us blocking the members that join our communities only to post spam.
