Yeah... it is in the best interests of your OTHER customers to make them an 
EX-customer.

Aloha,

Is it hard to remove them from your service for non compliance with your terms 
of use policy as well?

Hi all,

as I've started this threat I wanted to give you all an update on what we've 
learned but in fact what we probably all knew.

- customer is doing some bad practices and it's hard to make them change :-)
- check & double-check FBL's, unsubscribe & list-unsubscribe functionality
- if unsubscribe process seems to be too complex and a lot of users stop before 
actually unsubscribing, just identify the users by click & unsubscribe them
- Start Gmail warmup with low volume & highest engaged users
- do not send duplicates (we now only send the latest requested valuation  - We 
found out some users are receiving up to 20 emails with almost the same content)
- increase volume gradually & slowly
- increase volume with high engaged users
- keep track of complaint rate and only when low, increase volume
- keep track of view rate & click rate and only when high, increase volume
- Gmail: reputation can be tight to small content blocks (a phone number, a 
link, ...) test test & test to see the impact.
- Gmail: number of accounts are limited by your mobile phone number :-)

thx all for contributing, much appreciated! 

Jan Schapmans

In this case, "known trouble maker" is a vanishingly tiny possibility for a 
number of reasons.  Because of the change in the economic model Harris/Nielsen 
uses, their primary worry is fraudulent sign-ups by persons who can get a 
monetary gain by putting in a fake address.  

When I first attempted to sign up, I used a seed address in a wild-card domain. 
 The anti-fraud system will not permit signups from wild-card domains.
So, I used a non-wild-card domain.  However, apparently the IP had been flagged 
as a likely fraud source, and no sign-ups were accepted therefrom.

I explained the issue during one of our regular conference calls, and they 
manually added the seed account for some mailings.  Nobody that works there now 
was around when the "Nadine" narratives were posted, and just about every 
subscription policy they had way back then has been discarded and replaced with 
strict focus on confirmed voluntary subscription.

I dunno, I feel like those types of issues have always been there. I
agree that there have been some changes with Microsoft, but at least to
me those have been mostly positive.

As an example, I posted on here around 2 years ago that Microsoft was
blacklisting almost 400,000 IPs belonging to us, which at the time was
almost half of our network. At least back then, there were apparently no
other IaaS providers on this list, so nobody was able to provide any
help or tips on that. I started aggressively checking the SNDS each day
(on top of all the other sources we have), blocking spamming IPs, and
cancelling the accounts of spammers. Additionaly, I would often fill out
the delisting form Microsoft provides, sometimes with single IPs,
sometimes with a /24. I managed to get the blacklisted IPs down to
around 300,000, but it stayed that way for over a year.

Then, 2 months ago, the amount of blacklisted IPs plummeted to less than
10,000! It looks like something was "fixed" internally at Microsoft to
greatly reduce the number of false positives in their blacklist. I now
get hardly any complaints from customers regarding being blacklisted by
Microsoft, whereas before that was a very common occurence.

In addition, the SNDS updates much quicker than it used to. By around
10:00 CET I can view the data from the day before, whereas it used to be
two days late. This is a huge improvement and makes my job a lot easier,
since I get the info quicker and thus can act quicker.

So while there are still some issues with Microsoft, from my perspective
they are definitely moving in the right direction.
