Does volume cause blocking?

There seems to be a never ending debate about volume and how it affects delivery and revenue. I regularly get questions asking if ISPs block senders just for volume.
The answer is no. Unless you’re actually sending enough mail to overwhelm the incoming infrastructure, something that’s difficult on today’s internet, you’re unlikely to be blocked due to simply sending a high volume of mail.
Sending mail recipients don’t want, or mail that looks like spam, that will get the mail blocked or filtered.

That unsubscribe time of year

Like many people, I make purchases online. This usually means the vendor adds me to their mailing list. I normally don’t care, that mail all filters to my “commercial” folder (my own personal version of tabs) and I can browse it at my leisure.
At this time of year, though, email marketers go into a bit of overdrive and that folder fills with 20 – 30 or more emails a day. The volume is no so much of a problem, but it can get annoying to try and find mail I want in all the crud from random vendors.
In some cases, I don’t even know who the company is or why they have my address. Today’s example was a florist in Maryland. Eventually I figured out I’d purchased from them back in 2007 to send flowers to a colleague when her mother passed away. Apparently, they’re doing so badly they need every dollar they can find.
What it does mean, though, is that I unsubscribe from more mail in December than I do through the rest of the year. I don’t mind the occasional mail, even weekly is no big deal. But when that frequency drastically increases, or someone has not bothered to mail me for 5+ years, I just don’t want that mail anymore.

Censoring email

It seems some mail to Apple’s iCloud has been caught in filters. Apparently, a few months ago someone sent a script to a iCloud user that contained the phrase “barely legal teen” and Apple’s filters ate it.
The amount of hysteria that I’ve seen in some places about this, though, seems excessive. One of my favorite quotes was from MacWorld and just tells me that many of the people reporting on filtering have no idea how filters really work.
