Maximum outbound email size
Answer ID 10386 | Last Review Date 07/30/2019
What is the maximum size of an outbound service email?
We currently do not have any limits on the maximum size an email can be including attachments when sent out from Oracle B2C Service. However, outgoing messages are still subject to the limitations of the remote receiving server and each client or provider can vary. Therefore, it is recommended that the combined size of your message plus the attachment not exceed 30mb as it may affect the reliability with which messages are recieved.
