Total batch Email size exceeds individual max Email size

[malee1975]

Describe the bug The total Email size for MailJet is !5 including attachments. If Emails are batched for example a batch of 4 emails each of a size of 4 MB the API throws a 413 error: "Request Entity Too Large".

To Reproduce Steps to reproduce the behavior:

Send a batch of Emails that exceed 15Mb in total size without a single email exceeding this threshold

Expected behavior It is expected that within a batch that each Email is checked on an individual basis. There appear to be no documentation on batch size limits..

I received this answer from the mailjet support:

• you can make a total of 500 calls per 10-second time window
• you can have up to 50 individual emails in a single call or up to 50 individual recipients (To, CC, BCC); you can combine the number of emails with the number of total recipients in the call to any sum not larger than 50 (i.e. 20 separate emails, each with a To: recipient + 10 of the emails also having a single CC recipient, for a total of 50 messages and/or recipients)
• the entirety of the payload sent (body + headers) must not exceed 15 mb
