Why does the /send endpoint take so long to execute?

We deliver email to the providers SMTP server, we do NOT SEND email. When we deliver email the time for /send to complete is dependant on:

  • Attachments, these are uploaded.
  • Providers sender AV / SPAM checks

If a providers response is longer than others, please contact the providers mail administrator.

Once we receive a 200 response from the provider this means it has been delivered, not sent / received by the recipient.


Consider using the Outbox endpoint to handle email delivery, this will return a 200 immediately.
