Mass email

In the past (before I saw her true character-manipulative, controlling, etc.) she wouldn’t accept any my invitations, and if she did, she would put stipulations on the invite that would satisfy her (i.e. completely changing the place, time, etc). Now she keeps including me on a mail email blast, with 400 other people. I don’t wish to be friends with her, nor do I wish to receive her emails. We have mutual friends and I don’t wish them to be caught in the middle. What should I say and how should I say it to save everyone peace of mind?
In order to block her I have to delete her FB. Deleting her would create a world of problems. So I figured if I am going to delete her anyways, might as well let her know shy.

What do you think when you get a mass email from a friend entitled “Happy Holidays from us”, that incls a link to a page that shows (brags) about their vacation, their new car, their new job, their trip to the Oscars in LA, etc.? I generally get a text only email from them each year, and do loathe its arrival. However, this year, they included pictures, too. I understand the lack of time which warrants a mass email–don’t agree with it, but understand. The issue is that a holiday card should be something wishing the recipient happy holidays, happy new year, etc., vs. a vehicle to brag about the material things you’ve acquired or enjoyed this past year. And no, am not jealous, it’s from two *** men, and I’m a woman who does pretty well for herself. Is it just me, or is this poor holiday etiquette?
on a side note, i hear from them quite often and already knew about all these things.

I’m running a political campaign and will be sending out a press release to all the local media contacts tomorrow. How do I get them to notice it? I’m sure they get a lot of press releases and ignore most of them. Should I paste the text of it into the email and also attach it as an attachment? If it’s a mass email how do I address it — “Dear Member of the Press”?
