Another way Gmail is different
I was answering a question on Mailop earlier today and had one of those moments of clarity. I finally managed to articulate one of the things I’ve known about Gmail, but never been able to explain. See, Gmail has never really put a lot of their filtering on the SMTP transaction and IP reputation. Other ISPs do a lot of the heavy lifting with IP filters. But not Gmail.
While I was writing the answer I realized something. Gmail was a late entrant into the email space. AOL, Hotmail, Yahoo, even the cable companies, were providing email services in the 90s. When spam started to be a problem, they started with IP based blocking. As technology got better and content filtering became viable, improvements were layered on top of IP based blocking.
Gmail didn’t enter the mailbox market until the 2000’s. When they did, they had money, lots of hardware, and internal expertise to do content filtering. They didn’t start with IP based filtering, so their base is actually content filtering. Sure, there were some times when they’d push some mail away from the MTAs, but most of their filtering was done after the SMTP transaction. The short version of this is I never really pay any attention to IP reputation when dealing with Gmail. It’s just another factor. Unless you’re blocked and if you get blocked by Gmail, wow, you really screwed up.
Gmail does, of course, do some IP based blocking. But in my experience IP filters are really only turned against really egregious spam, phishing and malicious mail. Most email marketers reading my blog won’t ever see IP filters at Gmail because their mail is not that bad.
Other companies aren’t going to throw away filters that are working, so the base of their filters are IPs. But Google never had that base to work from. Their base is content filters, with some IP rep layered on top of that.
That’s a big reason Gmail filters are different from other filters.
Email pranks and spoofing
Earlier today a twitter user calling himself Email Prankster released copies of email conversations with various members of the current US administration. Based on his twitter feed, and articles from BBC News and CNN, it appears that the prankster forged “friendly from” names in emails to staffers.
A bunch of folks will jump on this bandwagon and start making all sorts of claims about how this kind of thing would be prevented if the Whitehouse and other government offices would just implement DMARC. Problem is, that’s not true. It wouldn’t have helped at all in this case. Looking at the email screenshots all of the mail seems to come from legitimately registered addresses at free email providers like mail.com, gmail.com, and yandex.com.
One image indicates that some spam filter noticed there may be a problem. But apparently SUSPECTED_SPAM in the subject line wasn’t enough to make recipients think twice about checking the email.
The thing is, this is not “hacking” and this isn’t “spear phishing” and it’s not even really spoofing. It’s social engineering, at best. Maybe.
Marketing automation plugins facilitate spam
There’s been an explosion of “Google plugins” that facilitate spam through Gmail and G Suite. They have a similar set of features. Most of these features act to protect the spammer from spam filtering and the poor reputation that comes from purchasing lists and incessantly spamming targets. Some of these plugins have all the features of a full fledged ESP, except a SMTP server and a compliance / deliverability team.
I’ll give the folks creating these programs credit. They identified that the marketers want a way to send mail to purchased lists. But ESPs with good deliverability and reputations don’t allow purchased lists. ESPs that do allow purchased lists often have horrible delivery problems. Enter the spam enabling programs.
From the outside, the folks creating these programs have a design goal to permit spam without the negatives. What do I mean? I mean that the program feature set creates an environment where users can send spam without affect the rest of their mail.
The primary way the software prevents spam blocking is using Google, Amazon or Office 365 as their outbound mail server. Let’s be frank, these systems carry enough real mail, they’re unlikely to be widely blocked. These ISPs are also not geared up to deal with compliance the same way ESPs or consumer providers are.
There seem to be more and more of these companies around. I first learned of them when I started getting a lot of spam from vaguely legitimate companies through google mail servers. Some of them were even kind enough to inform me they were using Gmail as their marketing strategy.
I didn’t realize quite how big this space was, though. And it does seem to be getting even bigger.
Then a vendor in the space reached out looking for delivery help for them and their customers. Seems they were having some challenges getting mail into some ISPs. I told them I couldn’t help. They did mention 3 or 4 names of their competitors, to help me understand their business model.
Last week, one of the companies selling this sort of software asked me if I’d provide quotes for a blog article they were writing. This blog article was about various blocklists and how their software makes it such that their customers don’t really have to worry about blocking. According to the article, even domain based blocking isn’t an issue because they recommend using a domain completely separate from their actual domain. I declined to participate. I did spend a little time on their website just to see what they were doing.
This morning a vendor in the space joined one of the email slack channels I participate in asking for feedback on their software. Again, they provide software so companies can send spam through google outbound IPs. Discussions with the vendor made it clear that they take zero responsibility for how their software is used.
I don’t actually expect that even naming and shaming these companies facilitating spam will do anything to change their minds. They don’t care about the email ecosystem or how annoying their customers are. About the best they could do is accept opt-out requests from those of us who really don’t want to be bothered by their customers. Even that won’t really help, even domain based opt-outs are ineffective.
What needs to happen is companies like Google, Amazon and Microsoft need to step up and enforce their anti-spam policies.
Social marketing
The following showed up in my mailbox a few moments ago
I commented to Steve that social marketing was about connecting with people, and businesses aren’t people. That’s why social marketing for B2B is hard: there are no people involved. Or, as he pointed out, B2B in the social space is bot to bot marketing.
Of course, there aren’t literal bots behind most brands. In the B2C space, brands have cultivated a social media presence that personifies the business in a way that appeals to their consumers. But that’s the brand projecting onto people and responding to people. When a business tries to connect to a business, it’s just two puppets talking.
Sure, there are small businesses where there isn’t the case. But generally businesses aren’t on social media to consume marketing. They’re on social media to generate marketing. They aren’t targets because you can’t market to a puppet.
Mike might be spamming, but why?
I’ve been talking a lot about ongoing B2B spam. That is, where senders drop your address into some sort of automation, that sends mail from gmail or amazon and just spams and spams and spams. This is what my mailbox looked like this morning
Yes, every one of those emails is sent to the same address. “you are still using the address laura-info@…” Well, no, actually. That was the original address I used as part of our contact on the first iteration of the WttW website. I stopped using that address somewhere around 2002? 3? It’s been a very long time in any case.
Folks, B2B spam is still spam. It doesn’t matter if you register a new domain and use Gmail as your outbounds as a way to avoid filters.
It doesn’t matter…
Domain management
Yesterday one of the bigger ESPs had their domain registration lapse. This caused a whole host of problems for their customers. It was resolved when someone completely unrelated to the company paid the registration fee.
It happens. Most of us know about cases where email or domains were lost due to renewal failures. The canonical case is one person at the company handles renewals, and leaves or is off when renewal comes up. The payment is missed, the domain goes back to the registrar and everything falls apart.
This happens at big companies and it happens at small companies. This is the kind of public facing problem that should make all of us look at how our own domains are managed. A few questions to ask.
Healthcare, eh?
I’m deeply disappointed in the vote out of the Senate today.
We’re a small business. We have paid for our own health insurance since 2002. We’re very lucky – neither of us has any major issues. Before ACA went into effect I worried about what would happen if one of us were to become sick. Would we fall afoul of our lifetime limits? Due to a rare cancer, my mother hit those back before I graduated college. Would our coverage be pulled because I didn’t mention the broken wrist from when I was 3? There were so many questions, and so many unknowns.
I watched the cost of our insurance go up and up. We bought a house in the Bay Area, and our health insurance was nearly 2/3 of our mortgage payment. Every year the price went up a little more, and the benefits went down.
Then ACA happened. I could stop worrying about lifetime limits and rescission. Our premiums dropped by hundreds of dollars a month. The costs of our monthly prescriptions plummeted to near zero.
Then Trumpcare and massive amounts of turmoil in the markets. Our group provider cancelled our policy and I’ve spent the last two months or so working with insurance agents to get ourselves covered. Our provider gave us 60 days notice. It wasn’t enough to ensure continual coverage. We were finally approved last week, with better coverage and lower premiums than we were paying pre-ACA.
I worry, though, about what happens to us if Trumpcare passes. Will premiums go back to where they were preACA? Will the small business market just evaporate? I don’t need a tax cut near as much as I need to know that the healthcare markets will be stable.
I want to focus on the things I’m good at. I know there’s a certain amount of administrative overhead related to being a small business owner and that these things are unavoidable. But still, there doesn’t seem to be any real benefit to blowing up health care in this underhanded fashion.
We are some of the folks who will get a tax break – not a huge one but we will be a beneficiary. I don’t think it will be enough to counter the jump in premiums – even if the premiums just go back to where they were pre-ACA.
I know policy is hard; I do it for a living. I know it’s not fun to watch the sausage being made – I grew up in DC. ACA has issues. But from my point of view the current healthcare debate is doing nothing to actually fix the issues. Instead, they’re making everything worse. Long term? We have options and money; we’ll probably be fine. But there are a lot of people who don’t have the options we do, and they’re going to be hurt.
This is bad policy, bad lawmaking and bad for small businesses like mine.
Implied permission
Codified into law in CASL, implied permission describes the situation where a company can legally mail someone. The law includes caveats and restrictions about when this is a legitimate assumption on the part of the company. It is, in fact, a kludge. There isn’t such a thing as implied permission. Someone either gives you permission to send them email or they don’t.
We use the term implied permission to describe a situation where the recipient didn’t actually ask for the mail, but isn’t that bothered about receiving it. The mail is there. If it has a particularly good deal the recipient might buy something. The flip side of not being bothered about receiving mail, is not being bothered about not receiving mail. If it’s not there, eh, no biggie.
Implied permission isn’t real permission, no matter what the law says.
Now, many deliverability folks, including myself, understand that there are recipients who don’t mind getting mail from vendors. We know this is a valid and effective way of marketing. Implied permission is a thing and doesn’t always hurt delivery.
However, that does not mean that implied permission is identical to explicit permission. It’s one of the things I think CASL gets very right. Implied permission has a shelf life and expires. Explicit permission doesn’t have a shelf life.
Implied permission is real, but not a guarantee that the recipient really wants a particular email from a sender, even if they want other emails from that sender.
I'm not a customer any more
We recently moved co-working spaces, after 8 or 9 years in the same place. I’ll be up front here, we left Space A because I was annoyed with them. I’ve been increasingly unhappy with them for a while, but moving is a pain so just put up with them. But their most recent rent increase along with the lost packages, increasing deposit requirements and revolving door of incompetent staff finally drove us to find a new co-working space.
On the 15th of the last month of our contract, I started receiving marketing emails from Space A. I just deleted a couple of them but finally decided I didn’t want to ever see their name again. I tried to unsubscribe.
Gotta give them credit. Checkboxes for everything, except some of them are to opt-in and some of them are to opt-out. This is the kind of interface marketers use to confuse folks and limit the actual number of opt-outs. I’ll admit, the first time I tried to opt-out, I probably did it wrong. But, I know CAN SPAM says they have 10 days, and I know many marketers take advantage of that so I wait a while and keep deleting the messages that show up in my mailbox.
That was late June. By early July I realize it’s been more than 10 days and I’m still getting mail from them. So I click another opt-out link. This time I notice I need to uncheck most boxes, but check the bottom one. OK, fine, you got me, I didn’t read and didn’t correctly opt-out the first time. This time I will.
I continue to receive email. I continue to delete the email. We run our own mail system so I don’t have the benefit of a this-is-spam button, but you can bet if I did I would have used it, on every message I received after my first attempt to opt-out.
This week, after getting yet more mail, I start digging. What ESP are they using that’s bungling the opt-out process? Ah. I know that ESP. So I send in a complaint to abuse@ESP asking them to please make their customer stop mailing me. I also go, once again, to the preference page and submit an opt-out request. Because, hey, maybe third time is a charm?
12 hours later I get yet another mail from them. Really? REALLY? OK. Now I’m moving from annoyed to irate. First step: figure out if I know anyone working at said ESP. Ah, right, them. I have a lot of respect for this colleague, so I send a heads up pointing out that their customer isn’t honoring unsubscribes and can they take a look at what might have broken in their unsubscribe process.
This morning they tell me they looked into my subscription and have not registered any opt-out request until the one this week. The other two? Not recorded in their system. “Does this match your recollection of what happened?” No. No it doesn’t. I know I clicked on unsub links at least 3 times and only one of those clicks is recorded.
At this point, I’m pretty sure I’ll be suppressed by the ESP so I won’t have to get mail from Space A any longer. That fixes the annoyance on my end. But I can’t help thinking about how horrible this interaction was, both from a deliverability perspective and from a customer perspective.
Online communities and abuse
A few weekends ago we met a friend for coffee in Palo Alto. As the discussion wandered we ended up talking about some of the projects we’re involved in. Friend mentioned she was working with a group building a platform for community building. We started talking about how hard it is these days to run online groups and communities. One of the things I started discussing was what needed to be built into communities like this to prevent abuse and damage.
