Thoughts on Gmail and the inbox

Over the last few months more and more marketers are finding their primary delivery challenge is the Gmail inbox. I’ve been thinking about why Gmail might be such a challenge for marketers. Certainly I have gotten a lot of calls from people struggling to figure out how to get into the Gmail inbox. I’ve also seen aggressive domain based filtering from Gmail, where any mention of a particular domain results in mail going to the bulk folder.
It’s one of those things that’s a challenge, because in most of these cases there isn’t one cause for bulk foldering. Instead there’s a whole host of things that are individually very small but taken together convince Gmail that the mail doesn’t need to be in the inbox.
A pattern that I’m starting to see is that Gmail is taking a more holistic look at all the mail from a sender. If the mail is connected to an organization, all that mail is measured as part of their delivery decision making. This is hurting some ESPs and bulk senders. I’ve had multiple ESPs contact me in the last 6 months looking for help because all their customer emails are going to bulk folder.
Gmail’s filtering is extremely aggressive. From my perspective it always has been. I did get an invite for a Gmail account way back in the day. I moved a couple mailing lists over to that account to test it with some volume and discussion lists. I gave up not long after because no matter what I did I couldn’t get gmail to put all the mail from that list into the tag I had set up for it. Inevitably some mail from some certain people would end up in my spam folder.
Gmail has gotten better, now they will let you override their filters but give you a big warning that the message would have been delivered to spam otherwise.

What are mailers to do? Right now I don’t have a good answer. Sending mail people want is still good advice for individual senders. But I am not sure what can be done about this ESP wide filtering that I’m starting to see. It’s possible Gmail is monitoring all the mail from a particular sender or ESP and applying a “source network” score. Networks letting customers send mail Gmail doesn’t like (such as affiliate mail or payday mail, things they mentioned specifically at M3AAWG) are having all their customers affected.
I suspect this means that ESPs seeing problems across their customer base are going to have to work harder to police their customers and remove problematic mail streams completely. Hopefully, ESPs that can get on the Gmail FBL can identify the problem customers faster before those customers tank mail for all their senders.

Spam is not a moral judgement
IP reputation and email delivery

Email marketing OF THE FUTURE!

ISPs are continually developing tools for their users. Some of the newer tools are automatic filters that help users organize the volumes of mail they’re getting. Gmail released Priority Inbox over a year ago. Hotmail announced new filters as part of Wave 5 back in October.
All of these announcements cause much consternation in the email marketing industry. Just today there was a long discussion on the Only Influencers list about the new Hotmail filtering. There was even some discussion about why the ISPs were doing this.
I think it’s pretty simple why they’re creating new tools: users are asking for them. The core of these new filters is ISPs reacting to consumer demand. They wouldn’t put the energy into development if their users didn’t want it. And many users do and will use priority inbox or the new Hotmail filtering.
Some people are concerned that marketing email will be less effective if mail is not in the inbox.

The challenge of Gmail

A lot of my sales inquiries recently are about getting good inbox delivery at Gmail. I’ve mentioned before, I can usually tell when an ISP changes things because they suddenly become the subject of a great many phone calls.
In this case, Gmail seems to have turned up their engagement filters and is sending a lot more mail to the bulk folder. I have also noticed other people are blogging about Gmail delivery problems. Al eventually determined that it was mailings sent from other IPs that were degrading the delivery of his customer’s emails.
Gmail, more than the other major ISPs, seems to not be weighting IP reputation very heavily these days. They’re looking at domain reputation and they’re using all mentions of a domain in that reputation. A lot of senders, some of them spammers, segregate their email streams (acquisition, marketing, transactional) across IP addresses in order to stop poorly performing mails from harming delivery of other emails they’re sending. But Gmail’s current filtering scheme seems designed to focus on domain reputation and minimize the impact of IP reputation.
This is making the Gmail inbox tough to reach for a lot of mailers these days. Even in cases where the mailer isn’t hiring affiliates or actively partitioning mail, if a domain is seen frequently in spam then delivery for that whole domain is hurting. Signing with DKIM and publishing a DMARC record may help. But the reality right now is that there doesn’t seem to be a silver bullet into the Gmail inbox.
