I received this email earlier this week, an email that I wanted but this is how it arrived. The email contained a single image link, a text line of who the message was sent to, the senders name, address, and finally an unsubscribe link. Good news, the email is CAN-SPAM compliant! Bad news, I have no idea what the content of the message is and it looks somewhat spammy. The email was sent to my...
PTR records are easy to over look and they have a significant impact on your ability to deliver mail without them. Some ISP and mailbox providers will reject mail from IP addresses that do not have a PTR record created. PTR records are a type of DNS record that resolves an IP address to a fully qualified domain name or FQDN. The PTR records are also called Reverse DNS records. If you are...
Yahoo has updated their FAQ and listed out a number of factors they use to determine if a mail message is spam. IP Address Reputation URL Reputation Domain Reputation Sender Reputation DomainKeys Identified Mail (DKIM) signatures DMARC authentication Autonomous System Number (ASN) reputation Autonomous System Number (ASN) is a globally unique number that is assigned to a group of IP networks...
I use tom@hotmail.com as my default bogus email address. Tom has subscribed to so many things because of me. This is why address verification doesn’t work. The address tom@hotmail.com is a real address. It exists. It accepts mail. And at least one person admits to signing up Tom for mail that the person doesn’t want. I’m sure he’s not the only one. <- 250 OK -> MAIL...
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...
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...
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...
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...
Like many bits of technology, email is often set-and-forget. Everything is checked and rechecked during setup, and then no one goes back and looks at it again. But mail programs are not static, and people make changes. These changes don’t really break things, but over time they can create their own set of problems. Setting aside some time every quarter or even every year to check and make...
I get a LOT of spam here. Most of it is marked and trivial to get rid of. Some of it is what I would call semi-legitimate. It’s a real product, but I never asked to receive any information from this company and am not actually part of their demographic. For one time things I just hit delete and move on. Life is too short to complain or opt out of every spam I get. (Tried that, got more...
