The twitter example is not advertising a product or service. It is conveying information about a product/service that the person has already hired.
 
If twitter sends unsolicited emails to someone when they have not requested that service, or have indicated they no longer want the service, then it is spam.

Hi,

From a recent rant in the WG, something of interest was posted;

> opinions on the proper definition of spam. Mr. Andre's preferred
> definition appears to allow for "one time" invitations to be blasted
> to everyone in the universe. Nonetheless, in Mr. Andre's considered

In my opinion, the sending of a confirmation email, from say Twitter,
to confirm that the actual email address does indeed exist and that
their further communications will be solicited - as well as including
links to remove/stop further communications:

Would be spam (it is still an unsolicited email) - but that single
confirmation email is not abuse in itself.

Even though Twitter may send 1000's of these to 1000's of different
email addresses...

I do not think that there is anyone, that works with actual spam abuse,
in this WG that disagrees completely with my opinion above.

Also, I wanted to add another useful resource link for anyone that is
still learning about email abuse:

https://www.ripe.net/publications/docs/ripe-409

What is frequently missed is that BULK EMAIL itself, is not the issue,
but that the keyword is "unsolicited" - For example if you were to
relay 1000 Invoices or 1000 status notifications or 1000 opted in
mailing list recipients, this would/should not be considered spam or
abuse.

Then, of course, imnsho UBE itself is outdated as the spammers use
'drip' systems by spinning out 10000's of emails from 10000's of ip's
Which various RBL cater for by speedily listing and de-listing resources
and then there are all the shiny new tech things, which probably needs
a new thread:

Automated comment spam or AI based web form spam is a growing issue
and is something that merits discussion and a watchful eye...
