Sending & campaigns

Sending, scheduling & campaigns

Send now, schedule for later, or run a bulk campaign.

You can send a single email or SMS now, schedule it for later, or run a bulk campaign to many recipients at once — from the SimpleSender or the API.

How campaigns work

A campaign creates an individual message record for every recipient, so each has its own status, retries, and analytics — a bad address for one person never affects the rest.

Quiet hours

Scheduled and bulk SMS respect quiet hours (set under Provider settings) so you don't message people at inappropriate times.
