Alternate contact when mail bounces

We received an invite from a local company recently. At the top of the invite there was a sticker. We attempted to send email, but your address bounced. Please contact either me or the tasting room to update. Thanks! We attempted to send email, but your address bounced. Please contact either me or the tasting room to update. Thanks! I signed up for their list in person. I’m not 100% sure...

Email can't be dead

Sitting in my drafts folder is a rant I wrote during one of the “email is dead” discussions. I think there’s a core of usefulness in my rant. The discussion was about how many click bait articles claim email is dead because people under 20 don’t have email accounts, or if they don’t, then they don’t check them. Almost everything online is tied to an email...

DMARC=BestGuessPass

Looking at the headers within the mail received with my Office365 domain I see dmarc=bestguesspass.  BestGuessPass?  That’s a new. A few days after seeing dmarc=bestguesspass, Terry Zink at Microsoft posted an explanation. Exchange Online Protection, the filtering system for Office365, is analyzing the authentication of incoming emails and if the domain is not publishing a DMARC record, EOP...

Clear and Clearwire.net

As of April 15th, Clearwire will no longer support their CLEAR Email/Clearwire Email services which include @clear.net and @clearwire.net mail domains. They were acquired by Sprint and these domains will bounce after April 15th 2015.

But all the technical correctness in the world isn’t going to make up for sending mail users complain about or don’t interact with. Recently we were working with a client who was having some...

Purchased Lists and ESPs

After some thought, I’ve decided to remove a few ESPs from this list based on personal experience with them allowing customers to send to purchased lists. If your company has disappeared and you want to come back, you’ll need to actually stop the spam coming from your network. Every company that’s been removed has received a complaint from me specifically mentioning the address...

iCloud Postmaster resources

iCloud Mail (mac.com, me.com, icloud.com) has a shiny, new postmaster resources page. No whitelist, no FBL, just a good list of best practices to follow for sending bulk mail.

What is the Mail From field?

When emails are sent, there are two from fields, the Mail From and the Display From address.  The Display From address (technically referred to as RFC.5322 from address) is the from address that is displayed to the end user within their email client.  The Mail From (technically referred to as RFC.5321 from address) is the email address to which bounce messages are delivered.  The Mail From field...

4 things spammers do legitimate marketers don't

I’ve never met a spammer that claims to be a spammer. Most that I’ve met claim to be legitimate marketers (or high volume email deployers). But there are things spammers do that I never expect to see a legitimate marketer doing. I’ve written about these things throughout the blog (tag: TWSD), but it’s probably time to actually pull them together into a single post. Use...
