Barry Levine says, “Here’s a new worry that digital marketers can add to their growing list:

A recent spate of email list bombings has led international spam fighter Spamhaus to block IP addresses from a number of well-known email service providers (ESPs), including possibly yours. (See below for advice on what you can do.)

And here’s the backstory:

On Monday, August 15, anti-spam consulting service Word to the Wise’s founding partner Laura Atkins posted about the difficult morning many ESPs were having:

“A number of ESPs [email service providers] woke up to a more-than-usually-bad Monday morning. Last night Spamhaus listed 10s of networks, including ESPs, on the SBL [Spamhaus Block List].”

She pointed out that Spamhaus was blocking IP addresses used by various ESPs, because those IP addresses were the source of email lists that were sending confirmation requests, newsletters and other emails to addresses that hadn’t signed up“.

Marketers, make sure you are not being list-bombed and blocked by Spamhaus
