We have an after work networking group called Healthcare Drinks. ([url removed, login to view]). Currently we send out invitations for the events in jpg format made in AI. We would like to have a similar invitation that is made in mailchimp so we don't have to count on the AI designer every time. We often make two invitations, one in English and one in Chinese. You can see two examples here. We also often partner with other groups so we need to put their logos into the invitation.
