I am the person that will be helping you today.
I must ask a question or two before we begin. Thank you in advance for taking the time to answer.
Who is your e-mail provider? Please, do not enter your full email address. If you do that, it will be blocked. For that reason, please tell me what comes after the @ sign.
Which program do you use to access your email (Outlook, Mac Mail, Entourage, Internet Explorer, Firefox, etc)?
Are you given any sort of error message when you attempt to send?
Thank you for the update. Are you able to send any emails at all? Please, send yourself a test email and see if that comes through.
They limit the number of emails you can send per day, to 500. After you reach the 500 mark, they will disable all outgoing emails for 24 hours.
In your case, being that you send this information to the same list of people, you may want to consider using Google Groups. Using Google Groups, you can send the message once, to the Group. Once you do that, everyone in the Google Group will receive the message. Google Groups is found on the following page: http://groups.google.com On the aforementioned page, you can click the Create a Group button. It will then ask for the list of people that you wish to add to the group.
I cannot answer that for you. Google may have incorrectly recognized your account to be sending out spam emails. I am sorry, but Google has no way to speed up that 24 hour wait time.
You will be able to send emails as soon as the 24 hour mark is reached. I do not know why they were blocked. Often times, they attribute something like this to a simple error in the Gmail system. When this Gmail 'hiccup' passes, you shouldn't have any more problems.
I can only imagine that maybe you sent some of the 400 emails later in the day yesterday. This would mean that you have sent them in the last 24 hours.
You can come right back here, if the problem still exists.
You will get me. Just come back to this page. You can also click the email that the site sent to you. It will bring you back here.
Thank you. I look forward to your rating of my help on this page.
