My Gmail username/password is not being accepted, what is going on?

FunnelFLARE uses your Gmail account to send all emails. There is a per-user setting on Gmail that will block third-party systems (Like FunnelFLARE) from sending emails. You can override this by going here

And setting the setting to 'true'. As you may be using more than one Gmail address, you must ensure you are logged in to the same account you are using with FunnelFLARE
