What you will learn

The campaign delivery modes and how send pacing protects your reputation on large lists.

​
Send now or schedule

On the Delivery tab:
  • Send now — when you confirm on Review, the campaign is queued and goes out shortly (the badge shows Queued until the send starts).
  • Schedule — pick a date and time; the campaign shows as Scheduled and fires on its own at that time.
  • Smart send — shows as Coming soon; it isn’t available yet.

​
Send pacing

Pacing spreads the send over a window instead of releasing everything in the same minute: When to use it: large lists, or a base still in warmup. Sudden volume spikes are one of the classic triggers for blocks at mailbox providers — spreading the same volume over a few hours delivers the same result without the spike. Two behaviors worth knowing:
  • Pacing is self-correcting. If one slice falls behind, the next one compensates — the campaign finishes within the chosen window, with nothing left over.
  • No one receives twice. Duplicate protection is per recipient, independent of how the send is sliced.

​
While the send is running

The campaign report follows along live (“Sending…”) and you can close the screen — sending continues on the server. If a send is interrupted midway, it resumes automatically from where it stopped (“Resuming automatically…”), and no one receives it twice. If the resume stops progressing for more than 10 minutes — or if the send fails —, the report shows the Resume sending button, which opens campaign setup with Resume pending recipients: it sends only to the pending recipients.
