A campaign is an email you send to a topic, optionally narrowed by a segment. The campaign list shows each campaign’s topic, segment, recipients, status, schedule and engagement, with All / Drafts / Scheduled views.
Create a campaign
Click New campaign and choose a build mode:
| Mode | Best for |
|---|
| Editor | Full control with Notion-style blocks. Type / to insert blocks: text, headings, images, a Button (CTA with label, URL and color), a Divider and more. |
| Assistant chat | Assistant-guided creation. Pick a goal (Newsletter, Product update, Promotion or Win-back) and the assistant drafts content, subject lines and preview text. See Building with the assistant. Consumes AI credits and needs a connection (offline switches to the Editor). |
Campaign settings
The settings panel groups everything you configure:
- Basic information: name and description.
- Audience: the Topic (required, one or more) and an optional Segment. The recipient count updates live as you choose.
- Subject & preview: the subject line and preview text.
- Email settings: From domain, From name and Reply-to.
- Send schedule.
Preview and test
- Live Preview renders your email for desktop, tablet and mobile.
- Send test emails a copy (with sample data filled in) to your own account inbox. Save the campaign first if prompted.
Pre-send analysis
When you choose Send or Schedule, Railmail runs a Pre-Send Analysis before anything goes out. It saves a draft, runs deliverability checks, then adds an assistant review and an overall score.
Checks include: link validation, spam score and spam words, subject length, personalization, unsubscribe link, image-to-text ratio, sender domain verified (SPF/DKIM/DMARC), recipient count, domain warming quota, merge tags, plain-text version, content length and per-topic consent.
Each check returns Pass, Warning or Fail with a severity:
- Critical issues block the send: you must resolve them before continuing.
- Warnings let you proceed with Send anyway / Schedule anyway.
The assistant review may be skipped if the score is too low, a critical check fails, or you’re out of AI credits. The deliverability checks still run.
Schedule and send
| Option | What it does |
|---|
| Draft | Save without sending. |
| Send now | Send immediately after saving. |
| Schedule | Send at a specific date and time. |
Campaign statuses
| Status | Meaning |
|---|
| Draft | Not yet sent. |
| Scheduled | Queued for a future time. |
| Queuing / Sending | Being prepared and sent. |
| Sent | Handed off for delivery. Open the report to see how many recipients actually received it. |
| Paused | Sending paused. |
| Cancelled | Send cancelled. |
| Failed | Could not be sent. Open for details or try again. |

For real sends you need a verified sending domain and at least one deliverable recipient. Domain warming can cap how many recipients you can reach per day. See Sending domain.
