How to deal with bounced e-mails?

Hi Theo,

Thanks for contacting us.

Could you confirm these are valid email addresses?

Our system will mark as a “Bounced” subscribers an email address that is undeliverable because:

• the recipient’s email address no longer exists;
  there’s
• a typo in the address (such as [email protected])

In some cases, if we detect you’ve been sending multiple times to an address and it has been soft bouncing (due to server issues), it may be marked as “Bounced” as well.

But we would not mark legit addresses as “Bounced” if we haven’t received a bad response when sending to them. So if you can confirm these email addresses are active, please contact our Support team via email to have them removed from our bounce list.

Thanks for your reaction.

The problem is solved. I have send an email from the same adress and I analysed the reactions (auto-replies).

I should have done that before, because the reasons were obvious: one adress didn’t exist, because the owner didn’t work with that firm anymore :-). I contacted another subscriber via Twitter and it seemed that she had more troubles with her hotmail-account, so she had another emailadress (which I didn’t know).

So problem solved ??
