Limits for sending and receiving mail
To help prevent spam and keep accounts safe, Gmail limits the number of emails you can send or receive per day, and the number of people you can add as recipients.
How to fix the problem
Look at the reasons below to learn how to prevent seeing these messages in the future.
Note: If you use your Gmail account through your work, school, or other organization, learn about Gmail sending limits through work or school.
You may see this message if you send an email to more than 500 recipients in a single email, or send more than 500 emails in a day.
When you get this error, you should be able to send mails again within 1 to 24 hours.
To prevent this from happening in the future, try creating a Google Group of all your email recipients and sending the message to that group's email address.
You might see this error if a large number of emails you send:
- Can't be delivered because the recipient's email address is invalid
- Bounce from the recipient's email server
You may be able to send emails again after 24 hours.
To prevent this from happening in the future, check your recipient's' email addresses before sending to make sure they're up to date.
If someone you’re sending mail to is getting too many emails too fast, you might see this message:
"The user you are trying to contact is receiving mail at a rate that prevents additional messages from being delivered."
You’ll need to contact the person another way.
You may see this message if you're replying to or sending an email whose recipients include a Google+ connection. This error isn't caused by breaking Gmail's sending limits, but is an issue that's being fixed by Gmail.
To prevent this from happening in the future, remove that recipient from the message.
