Understanding Email Status
When you schedule an email with Timezone Sending, the status behaves differently than standard sends:
"In Progress" Status:
- Appears as soon as delivery begins to the first timezone
- Continues until all recipients across all timezones have received the email
- Only applies to campaigns using Timezone Sending
"Sent" Status:
- Appears once delivery is complete for all recipients globally
Important Limitations
⚠️ Emails cannot be edited or canceled once the "In-progress" status begins
⚠️ Emails cannot be rescheduled retroactively - you must delete the scheduled send and recreate it to make changes
What Happens if Timezone Data is Missing?
If a recipient's timezone cannot be determined, they will receive the email at the scheduled time in your timezone (the sender's timezone).
The more precise your timezone data, the better the delivery accuracy. See Supported Timezone Data Formats for details on data precision.
