Sending bulk emails...

[cyberd]

Hi,
i ve created a vb app that i can send thousands of mails (to advertise my products to a my database members - 10,000 members) - i have my own mail server so.. i haven't limit from ISP... But the problem is SPAMHAUS.org - they blocked me one time...

and i am afraid to send again.. is there anyway to not blocked ?

what am i doing wrong ?

Thanks in advance

Well... Stop sending spam?

Seriously, unsolicited bulk email is spam. Pretty much by definition.


To get away from it I've been moving to services like http://corlive.com/

Slow down the application that sends the e-mails.
There are certain keywords that anti-spam server look for, therefore search on Google for common keywords for spam, and DON'T use those words...

Here is related thread created by me.

Have these users sais they want to recieve emails from you? And have you purchased this database?

[cyberd]

Users of database are from eshop site that i work for... and i am sending them Stock offers.. or newsletter.... The signup of member is for getting mail with new offers!

Well, I had to slow down the application to send 1 email every 1.5 seconds.

Any kind of delay, Sleep with DoEvents I think it's best. There are many people asking how to do delay on the forms, so just do a search on it.

AND that will help if i send 10,000 mails... with 1,5second pause at every email i will not flagged as spammer - right ?

[Pino]

No, there is no way to stop you being flagged as a spammer. You can do things that will reduce the risk,

If there is a program categorizing a sending as spam, it probably bases that categorization as emails/time, with a certain rate being sufficient to trigger the categorization. By slowing your sending sufficiently, then no automated process can identify your mailings as spam based on rate. Of course, a different kind of filter could be applied, such as one that looked for certain phrases, or compared how many emails came out that were identical. But consider what would happen if you sent one message per day. Would any program ever bother to track those sendings to identify them as spam? Probably not. How about one email per hour? That's still probably too slow for one program to see a pattern. Sending one every 1.5 seconds will probably be too slow for some pattern recognition attempts. Of course, if you are doing that, you will want to be doing so in a background process.

As far as I know frequent emailing is only used as a criterion by the ISP to block you as a spammer, to avoid their whole IP-range or domain from being blocked as a source of spam.

The spam-source vendors that email server providers use probably goes mostly off of compliants from customers. If a mail server notices customers tagging a lot of stuff from the same domain as spam they probably report the domain or server to those vendors (SpamHaus, etc.).

@ALL

What about if sending emails with time playing randomly from 3sec to 5minutes and changing email account to send it (like: [email protected], [email protected], [email protected]...) but always from the same ip - -- - can that recognized ?


@Shaggy_Hiker i can't send one mail per hour - i need more than 10000 hours... that's about 420 days!!!!

[CVMichael]

@ your first question
Why ? are you sending more than email to the same user ?

I think what you have to do is alternate the domains, like:
[email protected]
[email protected]
[email protected]
...etc...
[email protected]
[email protected]
...

@Shaggy_Hiker i can't send one mail per hour - i need more than 10000 hours... that's about 420 days!!!!

I know. It was just an example.

@cVmichael:
you mean more than one email ? ---In one month i can send 2 emails (new products if there are and newsletter)...

different domains not helping me... is too ugly to using free email.... want using my mail server...

Any other idea...

[cyberd]

For the moment i set a pause from 1.5sec to 35sec (randomly selects the time of pause) and sending 1000email / day... not bad... but little slow...

+ at the subject - i add the email of person contact to...
+ i put the word UNSUBSCRIBE (with reply) into email...

I think that this will no spam for spamhaus.... and ofcourse i am sending mails only at my members... So i believe that will not blocked!
