Are these the only email apps that work with Slack?
Probably not. A listing names at most eight integrations, so a tool that connects to Slack may still not say so among the eight it chose. 41 of the 52 email apps here do not name it; that is a "does not say", not a "cannot". Check the vendor's own integrations page before you rule one out.
Which of these email apps are free?
Spark Mail, Shortwave, eM Client, Mailbird, BlueMail, Help Scout and Fyxer are free or have a free plan.
