I read about the mass-mail feature that hides in the file menu. I’ve got a question and a remark about it:
Is there any kind of throttling in place? I know that sending out a lot of mails can kill your bandwidth enormously, especially when an attachment is send out!
The to: field is used to add mail addresses… Wouldn’t it make sense to use the bcc: field instead? Especially since a mistake can happen easily, and then everyone’s mail address get’s shared anyway.
Thanks for any comment

Hi Con, using bcc and mass mail feature is completely different.
While using bcc you still need to include the original sender which will be shown to all recipients.
Mass Mail sends the message to each person individually without knowing the name of a single other recipient. It’s used to send personalized emails to a group of folder possibly using variables etc.
However you can of course use the hidden copy option instead, depends on your preferences.

Yes, I am aware of that difference. What I mean is that if I put all addresses into the TO: field and press send by accident, all addresses are on the street. It would be better to use the BCC field for acceptance of email addresses for the mass-mail feature. If you then press send accidentally, the mail won’t go out because of the empty TO field. And even if it got out, it would be unreadable.
And what about the other question? I’ve seen many times that bandwith gets clogged because of too many mails trying to get out simultaneously. Is there some kind of protection for that?

Hi again Con, an email can’t be sent with an empty To field, that’s why we can’t use the bcc field instead.
Are you able to replicate such case? I’ve not come across this issue before and I’m unfortunately not able to replicate it.
Thank you,
Paul.
Also note that some mail services can have limits on how many messages can be sent using a single account over the SMTP protocol, there’s unfortunately no existing protection against this, only on the server side.

Paul.
Hi Paul,
My guess is that when you can programm that mass-mail uses the to: field, you could also programm that it uses the bcc: field 
A painful mistake could be avoided easily this way.
I have no example of clogging lines when using eM Client. But if there is no throttling in place that will definitely not be different with eM Client. We have seen this numerous times in standard outlook + exchange setups, especially when sending out attachements. All messages are dropped to smtp at once and that will clogg your bandwidth with collisions and retries. I believe that newer exchange servers have throttling possibilities built-in, but if you use standard ISP smtp you will not have that. Many mail listing programs have their own throttling, by limiting the number of mails per minute, or by imposing a (settable) pause between messages.
Might be a clever idea
Thank you for the suggestion, we’ll consider adding it to future releases.
Regards,
Paul.
I just came across this thread. I don’t know if the latest version is changed in this regard, but if you use it to make a “Distribution List” and put the list’s name in the Bcc field and your name in the To field no-one will see others’ addresses.
