This is one of the strangest issues in Zapier. The Read Receipt has to start as a trigger in a new zap. But the Read Receipt is never found though I am following the documentation step by step. I’ve tried immediately after sending the outbound email (with Email by Zapier), trying after a few minutes, sending the outbound email as a test trigger, sending the outbound email with different trigger. This Read Receipt can never be found.
Can anybody help? Thank you
