Difference between BCC and TO sending methods

[lsilman]

Hi, I'm a little confused about the difference between BCC (hidden bulk list) and TO (personalized list) methods for sending newsletters. My host has restricted the server to 500 mails per day, and just 75 recipients addresses per email. What method should I use? How can I do that with MaxBulk mailer?

I guess you mean the difference between the 'Singly' option being checked or not, right? It is recommended to avoid not using the Singly mode (bulk mode). Anyway in your case you could do it, set a group of 75 and stagger your deliveries manually in 500 chunks.

Thanks! If I use the Singly option checked, and set groups of 75, it will count for one email with 75 recipients, or 75 emails? Rgds.

 

[stanbusk]

It will send 75 messages, one per recipient.

Well... I've been testing the software (unregistered), but cannot send mails yet. I've tried ESMTP, Singly checked/unchecked, grouping/all at once... The only error I receive is "503 Incorrect command sequence" from my antivirus, but only when Singly is checked. The log says everything is okay. Do I have to register/buy to be able to send mails out?

You should be able to send messages with the demo as well. I there another 5xx error before the 503 one? Perhaps an authentication error?

I'm using Singly checked, and grouping 5 each 15 minutes. I've edited some info of the log above (mydomain, myaddress).

Sending to just one address doesn't work either. My SMTP settings are correct, and I can send emails using outlook.

Rgds.

It looks like your server doesn't accept the delivery of more than one address per session. I have never seen such a thing before actually. Could you ask the postmaster why they are so restrictive?

 

[lsilman]

I was thinking the same... so I run a test sending just to one mail, Singly checked, All at once, and I did not get the 503 error on the log, but didn't receive the email either.

Does you receive a '250 2.6.0 xxxx bytes received; Message accepted for delivery' response? If so, the server is clearly failing. It accepts the message for delivery but doesn't deliver it.

I got this in the log:

It says '250 Mail queued for delivery. '. That means the message has been accepted and will be relayed to final destination. If if never get delivered it is because the server fails to do it or perhaps a spam filter is deleting it.
