1) Do you offer SMS reminder delivery to countries in the Caribbean like Barbados under Tier3 of 38 credits per SMS?
2) If so, is there an option to purchase additional credits monthly? Even at 1500 credits per month, only about 40 SMS reminders can be sent which is quite limited especially if offering group meetings (e.g. classes, webinars)
Q: Question about invitees receiving calendar invites
I have a question regarding invitee notifications.At the moment, invitees receive a confirmation or reminder email, but they do not receive an actual calendar invite (e.g., an .ics file or a Google/Outlook calendar event) that they can save directly to their calendar.
Is this the expected behaviour, or should invitees also be receiving a proper calendar invitation automatically?

A: Hi - invitees should be receiving a calendar invitation as long as you've connected a calendar to zcal (Google or Microsoft) and set it to your write calendar.
Thanks for your respond but it doesn’t send a calendar invite - I have tested with different emails and in different ways but it doesn’t send an invite only a plain email :( happy to follow up in the support email to short out the issue.

Q: Business Plan feature as extra
I already purchased the Tier 1 plan. Is it possible to add the Business Plan features separately to this plan?
