When sending large campaigns, we prioritise the delivery before processing the reports. While your account is still delivering, you will only see a small number of deliveries and the majority will say 'Pending'. Once the campaign has completed sending, we will then prioritise the report processes and you will see deliveries coming in.
If the Pending status has lasted for at least 30 minutes or more, or affected a large number of contacts, contact us so we can look into the matter.
Watch our quick explanation of messaging statuses below.
