Does the EmailTask’s `email_to_cc` only allow for sending one email for cc?

Hi <@U01NA5HS1E3> - under the hood, the `EmailTask` implements the `smtplib` python module, which I believe supports sending emails to multiple recipients (including with CC) by providing a comma-separated string, i.e.: `<mailto:hello@prefect.io|hello@prefect.io>, <mailto:marvin@prefect.io|marvin@prefect.io>, <mailto:me@prefect.io|me@prefect.io>`

Thanks. I will retry. I was sending a list of strings earlier

The comments in the source code do make it sound like it's singular:

Ah, but <@U01NA5HS1E3> and I are running version 0.14.1, which has a different signature altogether:

So any additional args are probably just forwarded on as part of **kwargs

If that works <@U01NA5HS1E3> we can update the docstrings to reflect that :slightly_smiling_face:

I wonder if it would work to upgrade the agent's virtualenv to 0.14.11 even though the standalone server is still running 0.14.1. Anyone know if these are compatible?

Hm I'm not sure of the specifics there but I would say matching the server and agent versions is usually desirable, since the agent polls the API there's always a risk of a schema mismatch
