Major Calendly headache for invites not showing - Not remedied

This is a continuation of a thread that was closed 1 year ago, but the problem has not been solved by Calendly.  To wit: I spent almost an hour three weeks ago with one of the Calendly tech support reps on chat for the same issue, and I just had it happen again today.

The problem is this: The notifications message that Calendly sends out when someone books an appointment is being labeled spam and blocked from getting to the invitee’s mailbox– hence no appointment on their calendar and a no-show for me. On average, this happens with about 40% of the invitees that I have, and I suspect I have lost significant business because of this.

Now I'm not a tech person, but if this is happening multiple times, I would think that Calendly would do something to make sure that their names are not on the "blacklist” so that their emails are delivered.

My business can't afford this, and even though I have Calendly integrated into so many portions of the business, I am going to start looking for another solution because this cannot continue.

Pls see the attached email confirmation that I received. Additionally, the previous ticket about this issue which wasn’t resolved to my satisfaction is #3539881

The guest not receiving the email from [removed by moderator] (I think that is it) is blocked by the college / university. Sometimes is goes into the invitee’s spam folder, but most of the time it isn’t delivered so the person misses the meeting.

I think that if Calendly were to ensure their emails were whitelisted from the major spam filters, this would alleviate some of the issue. But I’m not a tech person - just someone who is trying to run a business.
