Sending to a large list

Iflow can send the same message to a large list in one go. Each send to a list is a job: Iflow queues the messages, sends them to the networks, and tracks each one individually.

Before you send

  • Check the cost. The total is the number of recipients multiplied by the number of message parts. One extra character or emoji can double or triple it.
  • Check your credit. If the account doesn’t have enough, messages fail with 9106. Accounts can also have a daily budget (9107) or a monthly credit limit (9111). See Credit and billing.
  • Send a test to yourself first, from the same sender, to see exactly how it arrives.

How a job runs

A job can show Complete before every message has been delivered: delivery reports, replies and opt-outs keep arriving afterwards. Check each message’s status in Delivery reports.

Duplicates

If the same message goes to the same number twice, the duplicate fails with 9120.
