FAQ

Questions about Mailchimp + Google Calendar.

How do I send a Mailchimp campaign right before a Calendar event?
Calendar Event Starting in 1 day → Mailchimp Send Campaign with the event details. Useful for webinar reminders or AMA announcements to your subscriber list.
Can I add Calendar event attendees to a Mailchimp audience?
Yes. Calendar Event Created → for each external attendee, Mailchimp Add or Update Subscriber. Tag with "event:webinar-2026-q2" so you can target post-event follow-up.
How do I send a post-event Mailchimp recap?
Calendar Event Ended → Mailchimp Send Campaign to the event-tagged segment with recording link, key takeaways, and a CTA. Standard post-webinar nurture.
Can I segment Mailchimp by Calendar event attendance?

Filter Calendar triggers to events with "[Webinar]", "[Public]", or specific tag prefixes. Internal calendar events skip Mailchimp entirely.
