Gmail filter undisclosed recipients - email

I'm trying to filter out emails from a specific user that BCC's everyone for group emails. I'd like to receive any emails that they sent directly to me, but the group emails are as good as junk. How can I filter for undisclosed recipients to keep these group emails in a folder?

According to this thread, you can try using the following filter:
deliveredto:myemail#gmail.com AND -to:myemail#gmail.com AND -cc:myemail#gmail.com
Even simpler, the following seems to work:
from:(sender#email.com) to:(-me)

email bounceback tracking with personalized subjects?

How do you handle email bouncebacks with personalized subjects? We send bulk emails to thousands of clients daily. Currently we run a script that combs our inbox and places all emails with the same subject into various folders that match our SQL database. This works great until a personalized email subject is sent. Because these emails all have unique subjects our script ignores these emails. Does anyone have any suggestions on how to handle this? We can't always say ignore the first part of the email because what if the personalized part comes in the middle of the subject. We thought about passing a unique code into the subject that would be hidden...but this doesn't seem to work across all email clients. Any thoughts or suggestions would be really appreciated. Thank you all!
*added so when our script runs it is done through a process that compares the subject to our database using a dictionary that looks for exact matches.
When the email is sent out personalized, are there phrases that you use to personalize the subject? If so, I would keep track of the outbound subject phrases and tokenize the non personalized parts of the subjects. When the message bounces back, and it matches a personalized outbound subject, you can strip out the personalized strings, and you would be left with a matching set of tokens in the subject that match your out bound subject tokens.
If the subjects are sent out automated but completely personalized with no common tokens, you can store the target address and subject on the outbound route. When you get a bounce back that is randomly personalized, you can look in the outbound storage for the same recipient, subject combination and infer that the message is a personlized subject that indeed bounced back.

How to send multiple mails at once with

I am interested how mailgun or similar services does send same message to multiple users with one call to user list, like described here
Is it just simple loop for each user or there is bulk mailing options for all SMTP servers.
I just want to create my own server for marketing newsletter to our users and was thinking about how to organize sending of mails.
I cannot comment on the back end of how specifically mailgun works, but I know when I have needed to do it in the past I have done it with a message, php array of emails and just sent them using php send-mail, just a for-each to loop through the list of emails and they would all be sent right off.

Outlook Email - Filter Creation

This is more of a product related question to increase productivity.
In outlook express, Is there a way to filter emails by senders who have sent only one email? Whether there is filter rule.
It would be awesome if we have that rule in Gmail as well.
Thanks!

Restrict email recipients based on email keyword in MS Outlook 2010

I work in a medical study where study coordinators at several off-site locations will be sending sensitive data via email attachments. These emails will be encrypted, but I cannot have the emails going to anyone but one or two specific recipients. I need a method to restrict who can receive email attachments based on a keyword in the email subject line. We are using MS Outlook 2010.
Ideally, it'd work this way: If the sender's email's subject line includes a keyword like 'RestrictedEmail' then only designated email recipients (for example, king#kong.com or robin#hood.com) can receive the email, else, the email will not send.
I didn't see this elsewhere in archives. Maybe I'm not using the right keywords...
Thanks in advance!
Trap the Application.ItemSend event, look at the message subject (Mail.Subject). If the match is found, loop through the MailItem.Recipients collection and check each Recipient.Address property to make sure only approved addresses are present.

For non-customized bulk email, is it better to use the BCC field, or generate a separate email with To header for each recipient?

I'm generating a bulk mailing each day for users who want to receive the daily deals. I can either send a separate physical email with each user specified on their own unique To header, or I can send one email with all the users on the BCC line.
Obviously if I ever want to create user specific content I will need to customize the emails per user and send them individually, but if I don't want customized email right now, should I just send out the single email with everyone on BCC? Any reason to NOT do that.
Edit: I'm using a third party as my gateway that specializes in delivery with CAN-SPAM compliance, etc.. not trying to do this off my own mail server...
Update: I guess I'm really also looking for some metrics here. Is there a difference in open rates of BCC'ed email vs To field email? What about spam filtering rules that might pre-classify based on the BCC field?
No reason I can think off for NOT doing it. Using BCC is the polite way to send bulk emails.
In this case, it turns out that the correct answer was neither. The gateway provided a custom header API that allowed me to specify all the recipients in a secondary "To" field. The API then handled the blind delivery of the emails, and also did variable substitution for me so I didn't have to transmit all the duplicate content multiple times. The API then handled doing "best practices delivery of the email".
