What does mitigation really mean?

It is a regular occurrence that senders ask filters and ISPs for mitigation. But there seems to be some confusion as to what mitigation really means. I regularly hear from senders who seem to think that once they’ve asked for mitigation that they don’t have to worry about filtering or blocking at that ISP for a while. They’re surprised when a few weeks or even days after they asked for mitigation their mail is, one again, blocked or in the bulk folder.

What is mitigation?

Think of mitigation as a flag that tells spam filters to ignore the history for an IP or domain. The history isn’t deleted or removed, it’s still there. But the “start date” is moved to the mitigation date. If I am a sender that’s been using an IP for a few years and I have a few bad months of sends in the middle, I can ask the ISP to mitigate the effect of those bad months on my reputation. The sender starts over fresh, with none of the bad history.

Mitigation is not a get out of jail free card.

Mitigation is not a get out of spam folder free card. This is not something offered to senders who have a poor history. It’s primarily intended for senders who are normally good senders but had some rough sends. The intention behind mitigation is to give senders a way to get out of the spam folder after they’ve fixed their problems. The infamous MS response “we see no problem with your delivery” in respect to spam foldering means exactly that according to their numbers, mail should be delivered to the spam folder.

Mitigation is not automatic.

In most cases mitigation is handled by a human being, that is following policy established by their employer. Real people review the internal data and dashboards and make a decision based on that review. Senders who have a long history of marginal mail are less likely to receive mitigation. The corollary is that senders who have a history of decent mail but a few bad sends are very likely to receive mitigation.

Mitigation requires plausibility.

Email delivery requires cooperation among senders and receivers. Mitigation requires trust on the part of the ISP, and every ISP rep has multiple stories of spammers who abused that trust. Senders who demonstrate they’re acting in good faith, by making receiver visible changes before requesting mitigation, are much more likely to receive mitigation. Repeatedly asking for mitigation decreases the chances of it being granted. Remember, mitigation doesn’t erase data, it simply resets the start time for analysis. The person handling mitigation can see that it was granted and nothing changed. It’s not a plausible request the second, or third, or fourth time.

Mitigation is an exception.

Asking for mitigation is a normalized pathway, but it’s not normal. Senders make the mistake of thinking if they got mitigation once, they just have to ask again. That mistake leads them to ask for mitigation without changing anything about their sends before or after the mitigation. As a result, they discover their mail is back in the spam folder. This also leads to mitigation not being granted a second or third time.

Don’t rely on mitigation.

No sender should rely on mitigation to get to the inbox. Instead, senders should focus on the fundamentals of good delivery: sending mail people ask for and expect. Everything else is rearranging deck chairs on the Titanic.

ISP filters are good for marketers

A throwback post from 2010 Attention is a limited resource.
Marketing is all about grabbing attention. You can’t run a successful marketing program without first grabbing attention. But attention is a limited resource. There are only so many things a person can remember, focus on or interact with at any one time.
In many marketing channels there is an outside limit on the amount of attention a marketer can grab. There are only so many minutes available for marketing in a TV or radio hour and they cost real dollars. There’s only so much page space available for press. Billboards cost real money and you can’t just put a billboard up anywhere. With email marketing, there are no such costs and thus a recipient can be trivially and easily overwhelmed by marketers trying to grab their attention.
Whether its unsolicited email or just sending overly frequent solicited email, an overly full mailbox overwhelms the recipient. When this happens, they’ll start blocking mail, or hitting “this is spam” or just abandoning that email address. Faced with an overflowing inbox recipients may take drastic action in order to focus on the stuff that is really important to them.
This is a reality that many marketers don’t get. They think that they can assume that if a person purchases from their company that person wants communication from that company.

Delivery and engagement

Tomorrow is the webinar Mythbusters: Deliverability vs. Engagement. This webinar brings together the ISP speakers from EEC15, plus Matt from Comcast, to expand on their comments. There’s been some confusion about the impact of engagement on delivery and whether or not senders should care about recipient engagement.
My opinion on the matter is well known: recipient engagement drives delivery to the inbox at some providers. I expect tomorrow we’ll hear a couple things from the ISPs.
