You could be trying to log into your Snapchat account with incorrect credentials.

Snapchat won’t accept your email, and state it is ‘invalid’ if you are trying to access your account with a different email address than the one you originally registered your profile with. Why does it say invalid email on Snapchat? With this guide, you will be made aware of all the possible reasons why Snapchat won’t accept your email, and what you can do to prevent this problem from occurring again, so you can successfully log into your account without any further setbacks. Making sure you are inputting the correct details when you are logging in, will stop Snapchat from declining your e-address. The instant messaging app refusing your address is predominantly caused by ‘human error,’ however, if the app has experienced a system issue, this can interfere with Snapchat validating your information.

Snapchat won’t accept your email if you have not verified your address, or you are trying to log in using a different email to the one you originally registered with.
