What’s a blast?
An email blast is a one-time send to an audience: product launches, newsletters, event invites, announcements. You pick who gets it, what they get, and when — Tented handles delivery, unsubscribes, and the results dashboard.First time sending? Make sure your sending domain is verified — see Setting Up Email.

Step 1: Pick the audience
Choose an existing static or dynamic list, or build a one-off list just for this blast (it’s deleted along with the blast, keeping your Lists page tidy).

Step 2: Pick the email
Use an existing approved email, or compose a one-off email inline just for this blast.
Step 3: Schedule it (or don’t)
Two ways to launch:- Schedule send — pick a day and time; the blast is approved now and sends automatically.
- Send now — confirm, and it goes to everyone qualified immediately. This can’t be undone, so the confirmation shows you the exact recipient count first.

Set as operational is for service notices — password resets, security announcements, terms changes. Operational sends go to unsubscribed contacts too and skip the unsubscribe footer — though contacts whose email was marked invalid by a hard bounce are still excluded (that address can’t receive mail). Never use it for marketing.
Or make it a test
Not sure which subject line (or send time, or sender) will win? The AB Test section under Additional Settings turns the blast into an experiment: up to five variations go to a sample of the audience, and the winner is sent to everyone else. See A/B Testing.A single blast can reach up to 250,000 recipients. If your audience is larger, the schedule step warns you before you launch — trim the list or split the send.
Watch the results roll in
The moment a blast sends, its page becomes a live results dashboard: recipients, sent, delivered, opened, clicked, bounced, unsubscribed, and spam reports.
Drill into any metric
Every number on the dashboard is clickable. Click a metric — say Delivered or Bounced — to open the Activity view: the exact contacts in that bucket, with timestamps (delivered at, opened at, and so on). A left-hand rail lets you jump between buckets, and there’s a search box to find a specific person.

Clone a blast
Running the same newsletter every month? Clone last month’s instead of rebuilding it: hover a blast in the Campaigns list and click the Clone icon, or use the ⋯ menu > Clone campaign inside the blast.
Archive a campaign
Campaigns that have actually run aren’t deleted — they’re archived, so their send history stays intact. Hover a completed (or failed) blast in the Campaigns list and click the Archive Campaign icon, or use ⋯ menu > Archive campaign on the campaign’s page.


- Drafts delete, ran-campaigns archive. A blast that never sent (and a flow nobody entered) offers Delete instead — there’s no history to preserve.
- In-flight blasts offer neither. A scheduled blast must be unscheduled first, and a blast that’s mid-send can’t be touched.
- Flows archive too — a triggered flow that has run contacts is archived once it’s paused. Active flows must be paused first.
- Archiving is permanent. There’s no unarchive — but everything about the campaign stays viewable under the Archived filter, and you can clone an archived blast into a fresh draft any time.
