says Farewell to Mailchimp


.. and hope to never see you again!

Yes, I closed my account because of so many issues in the past time.

First, it was because I had too many mails, then too many subscribers, then the emails below.

Due to the fact that probably some bots were registered, some sensitive keywords went in the email (after all, the website is about IT Security), they decided to block my account. And I removed it.


Because of the email addresses that were blocked, I received also the email below:

Imagine that from almost 2500 emails a few emails were probably fake, or somebody decided to mark my email as spam.

Emails that they subscribed for! ALWAYS! 

So, the only solution to identify which were the emails was to apply Divide et Impera, split the subscribers and add them in chunks of 300-400.

If a chunk was blocked, then, split them again, until I cleaned up the list. This is not possible in the same account (or I didn’t find how) and I created separated accounts. Of course, their system didn’t tell me which email addresses were with problems. So, there was no other way…

This probably attracted also their system to sniff that i used the same names (itsecurity) wherever I could. Why not, since I was not trying to hide anything.

Useless to say, this costed me a few hours of work across several days. And this is why I am so upset with Mailchimp.

I was planning to purchase an account after having cleaned up the mailing list (from 30$/Month).

Now, I exported the email addresses and I am looking a new home for them.

Until then, no daily digest for the people that subscribed before July 22, 2015.

I switched temporarily to Google’s Feedburner, hoping that they will not block me as well.


Will keep everyone posted with the progress.

Until then, if you know a reliable mailing system, let me know at sorin (at)
