    I have recently sent an email to our customers informing of our new bank details. There were approx 500 email addresses I sent this email to, using Outlook Express and the Bcc function (undisclosed recipients).

    Since doing this some of our customers and suppliers have incorrectly blocked our emails, so I am getting message failed every time I send them an email. Some of these I didn't even send the "bank details" email to in the first place.

    Can anyone suggest anything I can do to prevent this happening?

    Many thanks!

    Stop sending them using BCC, with that many recipients it will be flagged as spam faster than Husein Bolt does the 100m.

    Check if your blocked... Spamhaus host a fairly major blocklist service, used by many, and they have a page you can add your IP too.

    http://www.spamhaus.org/lookup/

    Also, I think you should perhaps look at a hosted solution, something like Mailchimp. Which is free for up to 2000 recipients and 12,000 emails a month.

    The "bounce" or undeliverable email should contain the reason why it wasn't deliverable.

    Can you post the body (removing any identifiable content such as ip addresses, email addresses etc) and we can advise you on where the issue is.

    It's so frustrating, I feared something like this could happen so I intentionally asked the guy who does our website (and marketing mail shots) what the best way would be and he suggested doing it like this!

    I checked spamhaus and in the Blocklist Removal Center bit it says "(our website).com is not listed in the DBL".

    Thanks Steve.

    Here is the failure message I am getting from one of our suppliers based in France. We distribute their products so email each other regularly,

    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:
    XXXX.com
    SMTP error from remote mail server after initial connection:
    host XXXX [XXXX]: XXXX
    Your access to this mail system has been rejected due to the sending MTA's poor reputation. If you believe that this failure is in error, please contact the intended recipient via alternate means.


    Here is another I have received,

    This message was created automatically by mail delivery software.

    Thanks - your server has definitely been blacklisted then.

    Go here: http://mxtoolbox.com/blacklists.aspx

    and enter the IP address of your server - it's shown on the bounce message here [XXXX] (remove the square brackets).

    Once you know what blacklist you are on, you can see why. Your hosting company should really take care of this though - it looks like you are on a server with "bad neighbours" (spammers).

    Hi Steve,

    The IP address in the square brackets is different on each failure message. I tried the IP listed in second email where is says "The server you are using to send this mail XXXX is currently blacklisted" on tmxtoolbox and everything (except of a few timeouts) has come back as ok.

    However, I have also mentioned this problem to our "website guy" and he was going to get in touch with the hosting company (Heart Internet) so they may have sorted it.

    I have just tried sending another email to our supplier and as yet have had no failure message! Hopefully they will respond to my email tomorrow....fingers crossed.

    Thank you ever so much for your help. :D

    In which case they are a muppet.

    Mass sending of email through your own host is often prohibited in the T&C so never ever do this again (just checked and Heart tell you not to do this in their T&C).

    As suggested, sign up for a mailing service. They are cheap as chips and dead easy to use.

    Once I started getting failure messages that is exactly what I thought too! Lesson learned. :redface:

    Can you PM me the full (untouched) bounce messages? I'll have a look for you :)

    When you send your bank details, all major email service providers automatically mark it as spam/junk email and many a time, it rejects.
    Most important is that, out of those 500 email address you have quite matching email service providers i.e. assume 50 users on yahoo.co.uk. And when you send to 50 users at a time, Yahoo mail server will definitely reject it as email bombing.

    Hence, you should send emails manually one by one. It must sound panic for you, but its the genuine way.
