It's not just you. I've certainly seen an increase in the amount of spam email being rejected by my servers in the last few weeks.
Spam goes in cycles for various reasons. Sometimes the command and control servers running botnets get taken down, which leads to a significant reduction in volumes. When a widescale breach of user details from a major site is announced, you'll usually see an increase in phishing emails looking to exploit that.
Last week my two mail servers rejected about 4,300 spam emails using a variety of methods. Only four people have email accounts on my servers so that gives you an idea how big the problem is. I think three or four spam emails got through but I've identified how they did and have updated the filtering.
Content goes in phases too. Today it's pharmaceuticals. Last week it was a mix of spam for erectile dysfunction pills and adult themed subjects like "I Missed Hookup Call". In the past it's been cheap counterfeit watches (see first link below).
There have been quite a lot of fake invoices recently - allegedly from Sage, Xero or Quickbooks.
In the past we've had these threads;
It's the scourge of the interweb thingy.
The proportion of spam in relation to the total number of emails sent seems to be falling
, which is a good thing.
Spamming, along with misapostrophecation, should be a capital offence
