A reader is having some issues sending Gmail messages to multiple recipients.  “Is there a limit to how many addresses I can send a Gmail message to? I am getting undeliverable messages say the address has blocked the email for everyone in the list.”


There are some limits when sending a Gmail message.  Users are limited to no more than 500 recipients in a single email.  You’re also not allowed to send more than 500 messages in a single day.   But users report seeing issues when sending to smaller lists of people. Personal Gmail accounts were not really designed to send messages to a large number of users.

What may have happened is that one of your recipients reported the message as spam, causing it to be blocked from being delivered to multiple senders.

You don’t say how many recipients are involved here.  But if you regularly send messages to 50 or so people at a time, you may want to consider using a bulk mailing service like Mail Chimp.
