@890,
I wish this question was in clear English.
I'm going to assume that you received an email notification after you deleted something on Facebook, and want to know how that's possible, and if Facebook can keep sending and showing things you've deleted (e. g. your deletion didn't "take").
That's not it at all; it's that your email was slow. Contact your email provider if it persists, but this is likely not Facebook's doing at all.
