Email Tool not sending every mail

[Dennisklad1]

Hello everybody,

I am using the Workflow below and send a report with the email tool to about 150 addresses.

For some reason do not all people receive the report. I cant figure out a pattern. 

Could this have to do with the server performance or with the smtp server?

Is there a way to validate who received the mail, like an excel or something?

Are there tools to resend email that where not received?

Thanks in advance!

@Dennisklad1 one reason why some users receive the email and other don't might be the size limitation of 10 mb of the email tool. https://help.alteryx.com/current/designer/email-tool.

If this is the case than please see a solution here: https://community.alteryx.com/t5/Alteryx-Designer-Discussions/Email-Attachment-exceeds-allowable-lim...

If you're separating your list of recipients with a semicolon, make sure there is NO SPACE after each one. I've had lists of users (specifically in the CC field) that get truncated as soon as a space is found.
