Volume

4 beelion emails

Sendgrid announced their volumes for Black Friday and Cyber Monday:

How much is too much?

Anecdotally I’m hearing a few different things about recent mail sends.

Wow! Congrats to all the senders out there for sending So Much Volume that mail servers are full. I’ve even seen reports that STARTTLS connections are taking multiple seconds to establish at Gmail. The volume of mail that it takes to make Google slow down is impressive.

Of course, Gmail isn’t the only system exhibiting slow downs. Other major consumer webmail providers are also showing signs their servers are under heavy load. I’m seeing reports about both AOL and Microsoft accepting mail slowly. Oddly enough, I’ve not seen anything about Yahoo having issues. Maybe folks just never use yahoo.com addresses any more.
There may not be a fix for this. It is very possible receiving systems just do not have the capacity to handle the volume of mail folks want to send today. If senders have, collectively, decided to send more mail than max capacity there isn’t much that can be done. Maybe some very forward thinking ISPs have spare servers they can deploy, but it’s unlikely.
No major advice here, just a warning that receivers may not be able to access all the mail that’s currently being shoved at them. Nothing to do except retry, and perhaps hold off some “less urgent” sends until after normal business hours. Those of you who are sending Cyber Monday sales emails may just have to extend them to Tuesday in some cases.
EDIT: After I posted this, I saw problems with Yahoo (mail accepted but not making it to the inbox) and Earthlink as well.

It's beginning to look a lot like…

I had a call this morning discussing holiday email volumes.

I think many consumers now expect the deluge of emails that start in early November. I’m not sure all of them want it, but I think they expect it. We’ll, of course, be writing more about holiday volumes, mailing issues and such through the end of the year.
What are your plans for sending all the mail? How have experiences in previous holiday seasons affected your planning for this one? Tell me how you’re approaching things.

An Advice Column on Email Delivery
When we work with brands and senders to improve email delivery, there are many questions that come up again and again. For 2016, we thought it might be interesting to answer some of those questions here on the blog so others can benefit from the information.
Confused about delivery in general? Trying to keep up on changing policies and terminology? Need some Email 101 basics? This is the place to ask. We can’t answer specific questions about your server configuration or look at your message structure for the column (please get in touch if you’d like our help with more technical or forensic investigations!), but we’d love to answer your questions about how email works, trends in the industry, or the joys and challenges of cohabiting with felines.
Your pal,
Laura

Dear Laura,
I’m having a hard time explaining to our marketing team why we shouldn’t send email to addresses on our lists with very low read rates, that are dormant but not bouncing, or that spend less than 2 seconds reading our mail. I’m also struggling to convince them that it’s not a good idea to dramatically increase email volume during the holidays (i.e. going from one send/day to 2-3 sends/day).
We already segment based on recency, engagement, and purchase behavior, and we also have some triggered messaging based on user behavior.
Can you help me find a way to help explain why sometimes less is more?
Thanks,
The Floodgates Are Open

Dear Floodgates,
ISPs ask two fundamental questions about email when it comes in:

Is it safe?
Is it wanted?

If the answer to both those questions is yes, the mail is delivered to the inbox.

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.

Is volume a problem?

Volume in an of itself is not a problem. Companies sending mail people want can send multiple emails a day to every user. The volume isn’t a problem because the mail is wanted.
Many senders are confused and think volume is a filtering criteria. It’s not. Send all you want; just send it to people who actually want the mail.
A lot of companies in their growth phase find they do have delivery problems as their volume ramps up. But the problem isn’t the volume, the problem is that mail programs don’t scale. Companies mailing lower volumes can get away with sloppier practices. One because the chances of hitting bad addresses increases with the number of addresses you have. But the other is that filters do take volume into account. It’s not that the volume directly causes the filters to trigger, but volume causes the filters to look harder at mail. If the reputation and metrics are good, the mail is fine and hits the inbox. If they are poor, then mail hits the bulk folder or is filtered.
Overall, volume isn’t a problem, but increasing volume can expose fundamental problems in a mail program that result in delivery issues.

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.
Dana Perino used the term ‘unsubscribe Tuesday‘

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.

Volume! Volume! Volume!

Saw a series of tweets this morning from random consumers about holiday marketing volume.

Quote of the day

Still working on the Gmail document. I got a little stuck today writing it, and have put it aside to try and work through the stuck place.
There was a very long discussion on Only Influencers today about frequency and un-engaged recipients. Lots of interesting opinions and a lot of people strongly welded to their points of view. One of the best comments came from John Caldwell, though.

Still more spam stats

Mailchannels put together another post looking at spam volumes. Related to that, many people are reporting that bot levels are climbing again.

Blasting the message!

Sending frequency is an important part of any email campaign. Too little mail and recipients forget about the mail and don’t open it when it does arrive. Too much mail and folks start complaining, like John Cole over at Balloon Juice.
