A bunch of folks today mentioned they were seeing poor reputation for formerly good reputations on Google Postmaster Tools. I’m seeing a lot of screen shots that look like this one.
It looks like something is going on over there that has nothing to do with actual reputation. Could be a reporting bug, could be a filtering problem. I’m not seeing people mention delivery problems, just that the reputation monitor is showing bad reputation.
M3AAWG has published a new version of the Senders Best Common Practices document and the contains a lot of new information since the original publication in 2008. The new document covers how to vet ESP customers, considerations when selecting a dedicated or share IP to send mail, and includes best practices on a number of technical processes.
The Senders Best Common Practices document is targeted at deliverability teams and email marketers. Any company that is sending marketing emails, using an Email Service Provider, or provides an email enabled platform, it’s always good to go back and periodically review your system to ensure nothing was missed and to stay up-to-date on all new recommendations.
A few of the recommendations include the use of the List-Unsubscribe header, publishing a clear WHOIS for domains used for sending mail, and how to process non-delivery report messages.
The List-Unsubscribe header provides an additional way for users to opt-out of email messages. Gmail and Outlook.com both use the presence of the list-unsubscribe header to provide a one-click button to allow the user to unsubscribe from the mailing list. Often enough, if a user cannot find an opt-out link, they’re marking the message as spam. Allowing a recipient to unsubscribe easily is critical to maintaining good delivery reputation.
A WHOIS is query to determine who is the registered user or assignee of a domain name. During a session at the most recent M3AAWG meeting, it was announced that spammers throw away 19 million domains per year. When a postmaster or abuse desk receive a complaint, they’ll often query to see who owns the domain the email was sent from or who owns the domains used in the hyperlinks. If the WHOIS record is out of date or set to private, this limits the ability for the postmaster or abuse desk to reach out to the owner of the domain.
Processing non-deliver reports is critical to maintaining a high delivery reputation. Many ESPs have an acceptable-use-policy that includes a bounce rate. Mailjet recommends a bounce rate of less than 8% and Mandrill recommends less than 5%. If a system is not in place to remove the hard bounces from your mailing list, the sender’s reputation will quickly deteriorate.

Earlier this month Google announced a new set of tools for senders at their Postmaster Tools site. To get into the site you need to login to Google, but they also have a handy support page that doesn’t require a login for folks who want to see what the page is about.
We did register, but don’t send enough mail to get any data back from Google. However, the nice folks at SendGrid were kind enough to share their experiences with me and show me what the site looked like with real data, when I spoke at their recent customer meeting.
Who can register?
Anyone can register for Google Postmaster tools. All you need is the domain authenticated by DKIM (the d= value) or by SPF (the Return Path value).
Who can see data?
Google is only sharing data with trusted domains and only if a minimum volume is sent from those domains. They don’t describe what a trusted domain is, but I expect the criteria include a domain with some history (no brand new domains) and a reasonable track record (some or all of the mail is good).
For ESPs who want to monitor all the mail they send, every mail needs to be signed with a common d= domain. Individual customers that want their own d= can do so. These customers can register for their own access to just their mail.
ESPs that want to do this need to sign with the common key first, and then with the customer’s more selective key.
How does it work?
Google collects data from DKIM and/or SPF authenticated mail, aggregates it and presents it to a Google user that has authenticated the domain.
How do I authenticate?
RadioShack is putting their assets up for sale including more than 65 million customer records and 13 million email addresses. Many are up in arms about the sale of personal data including the Texas Attorney General and AT&T who both want the data destroyed.
Part of the controversy is that RadioShack’s privacy policy states the collected data will be only used by RadioShack and its affiliates and that they will not “sell or rent your personally identifiable information to anyone at any time”. Company acquisitions happen all the time and data like this is often sold to the new owner and the sale of customer data is common. The problem with RadioShack selling the customer data is that their privacy policy states they will never sell the information.
RadioShack was one of the first companies to ask for personal information at checkout, sometimes refusing a sale without providing it and the collection of data during checkout caught on quickly. Having demographic information for retargeting of customers is extremely valuable to marketers, but only if it’s valid data. With RadioShack, people often lie about their zip code and if they are giving incorrect zip codes I’m pretty sure their email address isn’t going to be valid either. Even Kramer asks why does RadioShack ask for your phone number…

If a client asked if this was a good investment and if the list had value, I would tell them no. Sending to this list will have poor delivery because the data is dirty and the lack of a clear opt-in is going to be problematic especially since a RadioShack customer is not expecting to receive mail from you. Many ESPs have policies prohibiting sending to a purchased list and doing so will hurt your relationship with the ESP.
If a client had already purchased the list and wanted to send to it, I would tell them their reputation is going to take a significant hit and I would discourage them from sending. The list is going to be full of domains that no longer exist and contain abandoned email addresses including ones that have been turned into spam traps.
When preparing to send to a new list of email addresses, I go through this process:
