Warmup advice for Gmail

Getting to the Gmail inbox in concept is simple: send mail people want to receive. For a well established mail program with warm IPs and domains, getting to the inbox in practice is simple. Gmail uses recipient interaction with email to determine if an email is wanted or not. These interactions are easy when mail is delivered to the inbox, even if the user has tabs enabled.
When mail is in the bulk folder, even if it’s wanted, users are less likely to interact with the mail. Senders trying to change their reputation to get back to the inbox face an uphill battle. This doesn’t mean it’s impossible to get out of the bulk folder at Gmail, it’s absolutely possible. I have many clients who followed my advice and did it. Some of these clients were simply warming up new IPs and domains and needed to establish a reputation. Others were trying to repair a reputation. In both cases, the fixes are similar.

When I asked colleagues how they handled warmup at Gmail their answers were surprisingly similar to one another. They’re also very consistent with what I’ve seen work for clients.

Warmup Advice

Start small. Gmail recommends starting out with 10 – 20 emails at a time. They mean it. You can send this low number of emails every few hours, so you’re not stuck at 10 emails per day. Do not try to send even 100 emails on your first send for a new IP / domain combination. That mail will end up in the bulk folder.
Send to hyper engaged users. Simple engagement isn’t enough. You need to mail those people who are going to miss your mail and track it down if it’s in the bulk folder.
Sign up for Postmaster tools.  Use the tools, Padawan.
Expect it to take 4 – 6 weeks to fully warm a mailstream at Gmail. It will feel very slow in the beginning, when you’re sending out 100 emails over 10 hours. But that’s the right way to warm at Gmail. Once you are getting that mail to the inbox then you can start doubling volume every few hours.
You will need to warmup each domain/IP pair individually. Don’t expect that you can take a warm IP and add a new domain, or even subdomain, and not have to go through warmup. You will. Don’t expect to take a warm domain and get good delivery off a new IP. Gmail is really focused on the overall reputation of the mailstream, and making changes will lower or reset reputation.
If you get into trouble, slow down and back off. Refocus on your engaged users.
Some senders see problems if the mix engaged and new users into the early streams of mail.
It’s not impossible to warmup a new IP at Gmail, but it is a little different than warmup at some other places. It may feel too slow and too frustrating, but keep at it with those engaged users and it will happen.

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.

July 2017: The month in email

August is here, and as usual, we’re discussing spam, permissions, bots, filters, delivery challenges, and best practices.

One of the things we see over and over again, both with marketers and with companies that send us email, is that permission is rarely binary — companies want a fair amount of wiggle room, or “implied permission” to send. There are plenty of examples of how companies try to dance around clear permissions, such as this opt form from a company we used to do business with. But there are lots of questions here: can you legitimately mail to addresses you haven’t interacted with in 5 years? 10 years? What’s the best way to re-engage, if at all?
We frequently get questions about how to address deliverability challenges, and I wrote up a post about some of the steps we take as we help our clients with this. These are short-term fixes; for long-term success, the most effective strategy is sending email that people want and expect. Engagement is always at the core of a sustainable email program.
We’ve also discussed the rise of B2B spam, and the ways in which marketing technologies contribute to the problem. B2B marketers struggle to use social and email channels appropriately to reach customers and prospects, but still need to be thoughtful about how they do it. I also wrote about some of the ways that marketing automation plugins facilitate spam and how companies should step up to address the problem. Here’s an example of what happens when the automation plugins go awry.
I wrote a few posts about domain management and the implications for security and fraud. The first was about how cousin domain names can set users up for phishing and fraud, and the second was a useful checklist for looking at your company’s domain management. We also looked at abuse across online communities, which is an increasing problem and one we’re very committed to fighting.
I also highlighted a few best practices this month: guidelines for choosing a new ESP and active buttons in the subject line for Gmail.
And finally, we celebrated the 80th birthday of the original SPAM. If you’re a regular reader of this blog, you probably already know why unwanted email is called SPAM, but just in case, here’s a refresher….

The cycle goes on

Monday I published a blog post about the ongoing B2B spam and how annoying it is. I get so many of these they’re becoming an actual problem. 3, 4, 5 a day. And then there’s the ongoing “drip” messages at 4, 6, 8, 12 days. It is getting out of control. It’s spam. It’s annoying. And most of it’s breaking the law.
But, I can also use it as blog (and twitter!) fodder.
