What is the maximum number of recipients I can send to per message through your service?

The maximum is 50 recipients per message across the To, Cc and Bcc fields. For the best deliverability, we recommend sending a separate message to each recipient.

For more information on the 1 message per recipient method and why it is recommended please see why is it best to send email as one message per recipient?

Please note both methods have the same quota usage - 1 message with 20 recipients (either as to:, cc: or bcc:) will count as 20 messages sent - see how do AuthSMTP quotas work for more information.
