cipher - Interesting email I received?

This email recently arrived in my inbox. I don't know how it avoided the spam folder, but it must be important. However, it looks like a dictionary in a blender... you'll see what I mean when you read it.

If any of you can find a meaning or message in this, I'd love to hear it.

Partial meanings are welcome.

Update: I've recently received another weird, puzzle-seeming email. I've put it here in case it may have some relation.

Surprise, surprise. I got a third email. People have definitely seen codes in these, so I'm still not totally convinced they're a scam. Anyway, here it is, have fun.

Hi! One day left in the bounty, so I'm giving a really big hint. Hope someone can get it from this!

Look for double letters in part 1 broken between words.

Answer

First paragraph:

From the "Mega Hint", we are to look for double letters broken between words, i.e. a letter that comes at the end of a word and the beginning of the next word. (I don't know where this is hinted at in the puzzle besides the hint). Collecting those gives us:
VIGENERE KEY IS NINE

Second paragraph:

The email address backwards gives us "first letters in part two" (found by gabbo1092). This gives us:
SWEXUQEHCIEETZNTUZREQXEMZMFSATLGBCAXVVTYCNVVFBJSELVWGERRGG

Then, run that through a Vigenerer decode with key "NINE", which gives:
FOR THIRD PARAGRAPH READ PRIMES ONLY COUNTING UP FIRST WORD IS TWENTY

Third paragraph:

Setting the first word as 20 and selecting the prime numbered words (23, 29, 31, ...) gives us:
