How to ensure your domain isn't blocked?

[cusimar9]

We have one business which relies on advertisement campaigns, one of which involves sending out promotional emails.

Now the recipients of these emails are carefully chosen to ensure that they would be genuinly interested in our offers, but nevertheless it could be said that we send out unsolicited emails.

I should point out that so far we have only used each email address once, its not like we constantly bombard these people with offers.

My question is... how do I ensure our domain name doesn't get blocked for spam? When a domain gets blocked, Is it by the entire email address (ie me@mydomain.com) or just the domain (mydomain.com) name? Or is it by the IP of the mailserver?

As you seem to rely on this emailing promos, if your serious ask the people your emailing.
Opt in and out

One problem, after someone opts out you MUST NOT email them again, this would give you the highest chance of being listed. Most spam blocking guards block the *.domain.name then the mail server lastly the IP as this is normally dynamic for real spam.

good luck

But did they choose you, did they ASK to be contacted (i.e., sign up for your service)?

Any unsolicited email is spam and grounds for blocking by an ISP or other action. Even just one. The reason I asked the first question is that it's even worse if you don't know the origin of your mailing list.

If you don't know the origin of your contacts, then it's a bad idea. If you proceed anyway, make sure that your email has a link to or method of unsubscribing and make sure it works.
