We deliver both ongoing and one-off emails as quickly as possible to your selected users. The time it takes to deliver your message is based on two major factors:
The number of users you're messaging (the more targeted your messages are the quicker they’ll be delivered).
And the state of our queues when you hit the send button.
Why do emails to smaller groups of users deliver faster?
We batch message delivery into several logical units of work and each stage is processed on a queue. Messages sent to a smaller number of users get placed into higher priority queues. Therefore, the more targeted your messages are the faster they’ll get delivered.
Alura will check every 15 minutes for any emails that users should receive.
