Hi all,
I have used the "Send E-Mail" smart service to send emails with attachments in my process model. I got the error "Failed to send Email" in a process that errored out at the node "Send Email". When I analyzed the file size I found that one of my attachments had a file size of approximately 61 MB. What is the maximum file size allowed in Appian "Send E-Mail" smart service for attachments?
Thanks in advance.

I think this is mostly restricted by the mail server the email is sent to.
Agreed with Stefan - fyi very very few mail servers out there will accept an email over maybe 20 megabytes at max. Some would accept even less.
Thank you, Stefan. This issue has happened in the production environment. So do I need to clarify with the client the maximum file size their mail server can accept? Is it entirely dependent on the mail server and not related to Appian functionality? Just to confirm.
Yes
Thank you Stefan. I will find out the maximum file size the client's mail server can accept and apply validations accordingly in the file upload field to prevent this error.
Thank you, Mike. Your answer was helpful for me to know the approximate file size limit for email attachments.
