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

By default our system is configured to allow up to 50 recipients per single message - this can be increased to a maximum of 200 recipients but it is not recommended as it can have a negative impact on the deliverability of your emails.

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?

If it is not technically possible for you to send 1 message per recipient and you understand the deliverability implications you can increase your maximum recipient limit by logging into the control panel and you will find the option under 'Advanced Config'.

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.
