4 beelion emails

Sendgrid announced their volumes for Black Friday and Cyber Monday:

To provide a clearer understanding of our scalable systems, on Black Friday 2019 we processed 4.1 billion emails and this Cyber Monday we processed 4.2 billion emails (46% more than 2018) and processed up to 315 million emails/hour (burst rate) into inboxes all around the world! To give you a better understanding of this scale, you can get to the moon and back 4 times in fewer yards than the number of emails we sent on Black Friday.

That’s more than double the volume they sent in 2017.

I expect other large senders did similar volumes, which makes the total amount of email over the last week mind blowingly huuuugee.

How much mail did you send?

Successful sends on Black Friday

Last year a number of ISPs mentioned the Black Friday email volume was congesting their systems and causing delays. While anecdotally it seems that volume is up over last year I also haven’t heard any ISPs talking about congestion. Likewise, most of the delivery folks I’ve spoken too today and over the weekend are saying there were no major problems.

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.

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.
