Why do ISPs limit emails per connection?

A few years ago it was “common knowledge” that if you were sending large amounts of email to an ISP the most polite way to do that, the way that would put the least load on the receiving mailserver, was to open a single SMTP session to the mailserver and then to send all the mail for that ISP down that single connection. That’s because the receiving mailserver is concerned about...

Email Marketing for Dummies

Mark Brownlow has an interview with the author of Email Marketing For Dummies. It is a great summary of the book and gives some good hints to anyone interested in starting to use email as a marketing and customer retention tool.

Success!

A few weeks back I posted about changes a client of mine was making in order to improve their IP reputation and their delivery. They are now getting inbox delivery at the major ISPs.  Their actions are up and  they are seeing great results. They did not implement all of my specific suggestions. Instead, they took the underlying advice, and modified it to fit their needs. They took my advice to...

Changes at Comcast

I can usually tell when one of the ISPs makes some change to their incoming spam filtering just by my call volume. The past few weeks the ISP in most of my calls has been Comcast. And, what do you know, they have made changes to how they are filtering email. According to their bounce message, Comcast is using ReturnPath’s proprietary SenderScore product to filter mail. Reports on thresholds...

Best practices and ISPs

A couple articles came out today talking about ISP requirements and how to find them.
EmailInsider talks about ISP best practices and how merely complying with CAN-SPAM is not enough to get good delivery at the ISPs.
Meanwhile, over at ClickZ, Stefan talks about what the ISPs want from you and how to find the information online.

Why does everyone tell you to avoid .biz in your emails?

… or Why do spam filters sometimes have some very strange ideas? It’s been dogma for a long time that if you’re doing email marketing you should avoid using a .biz domain in your mails. Even if your main website was in .biz, you should use something different in your messages, perhaps a website you buy solely for use in email that redirects to your real .biz website. Last year I...

Useful websites

I’ve been working on a document discussing laws relevant to email delivery and have found some useful websites about laws in different countries. US Laws from the FTC website. European Union Laws from the European Law site. Two documents on United Kingdom Law from the Information Commissioner’s Office and the Data Protection Laws Canadian Laws from the Industry Canada website...

When to send mail

I had a call with a potential client recently asking me what was the best day to send mail. It’s a question that I did not have a good answer to. Email Insider does have an answer to that question: there is no one day to mail to get the best response. Even if there were one universal best day to send email, it wouldn’t make sense to send your email the same day as everyone else. In the...

Spam in the workplace

In comments on my last post Lux says: It seems to me that in regard to PR people sending press releases to a professional journalist, you’ve got a very specific use case with slightly different rules of engagement from the norm. I think that is a valid point and that some people, because of their job, will receive mail they do not want or have not asked for. I also think that the business has the...

Changes at AOL Postmaster desk

The recent layoffs at AOL did affect the AOL Postmaster desk, and information I have received is that there was significant loss. As a result of the staff decrease, some changes have been made to the whitelisting and FBL processes. In order for a FBL to be approved it must meet the new FBL guidelines. In a nutshell, anyone wanting to get a FBL from AOL must meet ONE of the following criteria. The...
