Send email in .net application without it being spam?

[Samnang]

Hi,

I have a list of email address of my customers, I would like to build
an application that can send product promotion to them in regular once
a week. I'm afraid that my email will deliver as spam, could you give
me some advices to avoid this problem?

Cheers,
Samnang

Hi Samnang,

the problem is on the server an customer side.
If you are on a black list with spamers, then
you must contact the lists maintainer to delete
you from the list. You also must contact your
customer and tell them that they must arrange
it that way (server settings, email client settings,
spamfiler settings, everthing that could block your
email from reaching your inbox on you mail client!),
that the mail will be delivered to the mail clients inbox.

It is not a .NET Problem, more a infrasctructure solution
that must be considered,...

Regards

Kerem

If it is not spam then the following will help:

Always start the subject with a consistent prefix identifying the type of
mail you are sending. '[Bulk]' for example. The emails from my son's school
are always prefixed with the schools initials, etc.

Always include an opt-out url that will automatically remove the person from
the mail list and respect this.

Send in small groups of individuals to each server and spread out your
transmissions over 24 hours or so. The more mail you send and the more
connections you make to each server in a given time frame increases the
likelyhood that you will be considered spam.

Make sure that your return email addresses are correct, are synchronized
with the IP address you are sending from and point to a server that is not a
known source of spam. If your hostname and return emails do not match up
with the sending IP you will almost immediately be filtered out, in many
cases before the mail server has even processed your email.

If you do these things, it is unlikely you will be labeled as spam.

If you really have something interesting for your customers, consider
instead setting up an RSS feed and telling them how to configure this in your
emails.

There are many reason why your email could be marked as spam..
1)your server is black listed because its an open relay
2) a particular isp received too many emails in 24 hours period from
one ip ( aol does this)
in this case the email either gets bounced back or goes to spam. i
don't remember which.
3) reverse look up of the sender host does not match sender machine.
ie. if you are sending from (e-mail address removed) , then reverse look up
for ip crap.com's MX should be crap.com
4) SPF check fails

I worked for this company which sent out a lot of emails. We finally
moved to fully managed email solutions.
