Cobot allows you to send emails to either a single member, a group of members or all members.
For newsletters we advise to use a dedicated newsletter service like MailChimp - sending newsletters without using a dedicated service might get you (and us) into trouble with email spam. In addition newsletter services allow you to track open rates, send HTML emails and such.
You can also send email to a single member on Cobot go to that member and click on their email address displayed below their billing address.
To send an email to a group of members go to the member list page, use the filter field at the top of the list to shrink the list to the people you want to send an email to and then click the Send Email to List button.

We also offer a Slack Integration to allow your members to be automatically added to a team Slack channel for your space. This would allow you to communicate with the members of your space instantly (as long as they have Slack of course!)
