For the email, you can send the email with all those addresses in the BCC field. Check out javax.mail.Message#addRecipient(s). The maximum number of addresses on the BCC list depends on the mail server. If you can't send everything in one go, send out a few emails instead:

Address[] addresses; // the array with all addresses; this could of course also be a List or Collection
Message message = <create message with everything but the BCC>
for (int i = 0; i < addresses.length; i++)
{
    if (i != 0 && i % MAX_NUMBER_OF_BCC == 0)
    {
        // the message is full
        <send message>
        message = <create message with everything but the BCC>
    }
    message.addRecipient(Message.RecipientType.BCC, addresses[i]);
}
if (message.getRecipients(Message.RecipientType.BCC).length > 0)
{
    // send the last message with the remaining addresses
    <send message>
}

Because you're using BCC you will not show all the email addresses to all recipients, and that will decrease the chance that those addresses end up on some spam list.

You will probably need a CC or TO address as well, but you can use your own address for that.


I don't know how to send SMS messages with Java but the principle is the same. You may have to send those one at a time in a loop instead of grouping numbers together like the BCC solution.

Thankx
But i dont know how to start .Please help me how to start this project.
My planning about this project is :
1. Make a home page(html page) asking some details such as my id,message which i want to sent and submit button.
2.After submitting ,a servlet handles this form data and get email ids from sql server database and connect to a email service provider and then put those email ids in BCC field.

Thats all which i know .But i dont know how to connect to email service provider and how to put those email ids in To or BCC field.
So please correct me if i am wrong or suggest me better.Is it possible which i have mentioned in 1 and 2 points.

Then your first step is to read up on them: here (focus on the javax.mail and javax.mail.internet packages).

Start with design first. Does your data come from a database? How often are you going to run it? Things like that. Once you have a design, then write code to implement the design.

You do have your own SMTP server to send these bulk mails, right?

And this forum isn't really a helpful place for vague questions like that. What I have just posted shouldn't have to be said at all. But if you have specific questions about the design or the implementation, this would be a good place to ask them.
