Why can't I sign up with a temporary email?

Why can't I sign up with a temporary email?

If you have registered on sites like Facebook or Instagram, you have probably encountered a situation where your email is not accepted or a confirmation email with a code is not sent to you. This is a result of a hidden security algorithm that blocks your registration as undesirable.

There can be many reasons for this to happen, and here are the main ones:

1. Public domains. When you create a temporary email with a public domain, no one can guarantee that it is not already on the blacklist of the particular service you are trying to register for.

For example, if the email address use239@cooltempmail.com is blacklisted by the service, the whole domain @cooltempmail.com may be blocked as potentially risky.

2. Blacklists. Many services simply do not like temporary email and prefer to ban their usage.

While Temp Mail keeps the list of domains constantly updated, even we cannot promise 100% that the desired service will accept your temporary email.

As a result, your registration with the service may be rejected or your account may be put on hold.
