You could at one time depending on which email provider you used click on delete on entry for any blocked senders. Unfortunately a few good senders used to get blocked as well.
I used to use mailwasher pro and you could delete spam from there before it got to your main email account. Now I know that they do a free version but have never tried that.
maybe check your contacts list to make sure you do not have anyone in there that should not be in it.
If you do not have many contacts maybe a new e-mail address would be best.
An e-mail address for friends and family only and another e-mail address for general use would be best.
I hope someone else can give you the advice that you need as there is nothing worse than getting e-mails that you do not want.
