How do I send emails to a lot of people, recipients at once?

As far as the description of the problem i can guess you are not been able to send emails to the lot of recipients or people where most of them are in your address book too. And yes this is not the problem on yahoo mail, same problem will occur in gmail as well as on windows live hotmail.

And the answer of this problem at which you are not been ablr to send email to millions or thousands of people because of "Spam" Yes spam is the main problem which cause you to not send email to thousands of recipients of your contacts.

There are certainly various more reasons also but the main reason is spam as i told you. One solution which you can use is the "Yahoo groups" Make one yahoo group and send the invitation to them one by one and ask them to join. But the problem is that what if you are using some other email provider than yahoo.

So As far as i concern the best approach to send email to lots of contact is to separate those contact in short group like if you have 1500 contacts then make 30 groups on your yahoo or windows live hotmail or in gmail and add recipients on those 30 groups. Now send the specific email to each group.

I think this can be the best alternative for you if you want to send lot of email once.

There are more alternatives also which you can use to send email to lot of people. Some of them are listed below.

• Register to any bulk email sending websites at which you can send thousands of email which only just one click.
• Ask your recipients to subscribe any service if you with this also you can be able to send emails to lot of people if you are providing the particular service.
• Use yahoo group or any other group for sending lots of email to recipients. community at orkut is also one of the example at which community owner or moderator can send email to all the users of community with just one click.

Those are some of the ways with which you can send email to lots of people with one instance.
