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.

Does mail volume contribute to blocking?

There are two extreme opinions I see among marketing agencies and email senders when it comes to volume.
One group seems to think that volume alone triggers blocks. Another group thinks volume never affects delivery.
As with many things in delivery reality is at neither extreme.
Sending lots of mail isn’t the problem. Sending lots of mail your recipients aren’t interested in getting is the problem. Last year during the US political elections the Obama campaign, for instance, sent lots and lots of mails. Their list was an order of magnitude larger than the Romney campaign and there were days they were sending 10s of mails per subscriber. It was a deluge. But they were smart, and they did a lot of data mining and they did it in a way that got recipients to act on the mail. That mail was a deluge, but it was a wanted deluge by most of the receivers.
For a lot of vendors, too, increasing volume does increase response and revenue and all the things you want to drive with email marketing. But there will be people who don’t like the increase in volume. If they’re not valuable customers, no great loss. If they are valuable customers, then the increase in volume may drive a decrease in revenue.
In terms of inbox delivery, it’s not the volume it’s how wanted the mail is. Send wanted, interesting and engaging mail, you can send dozens of times a day.
No, volume alone doesn’t contribute to delivery problems.

Contacting an ISP that doesn't have a postmaster page

How do you contact an ISP about a block that doesn’t have a postmaster page? While there’s no one answer, I do have some suggestions.
Start by contacting the postmaster@ or abuse@ addresses. For smaller ISPs, the same people handling outbound abuse are the people handling inbound filtering.
When you contact them have the following:

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.
