What error message are you getting?

I haven’t tested this myself yet, but I think you can just send it to their email address within Slack (i.e. put their email address in the Channel/User field), and it should automatically create a private message to them.

Otherwise, you might need to put the # symbol before the conversation ID.

This support article is missing lots of information, but it might contain something helpful for you somewhere within the article:

Thanks @ScottWorld !

A lot of our engineers are not very active via email so I would prefer to send a Slack message. Or did you mean the email would connect to a Slack message?

I have tried adding the #, but it didn’t work either.

Attached is the error message I am getting.

Yes, what I meant is to insert the email address as the channel name. See if that works.

Yes, it works, but it only sends a Slackbot message which does not attract as much attention as a private message and also doesn’t leave the opportunity for them to reply back directly.

By the way, I figured that the numbers appeared because I set “length of channel”. But I had tried “value” before, and it still didn’t work…

Ah, good to know about the Slackbot sending the message! Thanks for letting me know about that. Yeah, that’s not very helpful.

Are you putting the right conversation ID into your Channel field? Like you said, don’t use the length of channel, put the actual ID of the conversation.
