If you’ve used a traditional newsletter tool, the campaign concept will be familiar. Pick a slice of your audience, write the email, hit send, and watch the metrics roll in.
What a Campaign Is (and Isn’t)
A campaign in Lettr is one email going out to one batch of recipients at one point in time. Campaigns are not drip sequences, automations, or RSS-triggered sends. If you want to follow up to opens or non-opens, schedule a second campaign manually — there is no built-in series feature today. Beyond that, the model is intentionally simple:- One content (HTML body, subject, sender details)
- One audience selection (lists, segments, or all contacts)
- One schedule (send now, or pick a future date/time)
- One report (engagement metrics after the send)
Prerequisites
Before you send your first campaign, make sure you have:- A verified sending domain for the address you’ll send from
- At least a handful of
subscribedcontacts in your audience — or a list or segment you want to target - Either a template you want to base the campaign on, or content you’ll build directly in the campaign editor
Campaigns are part of Lettr’s marketing plan. The free tier includes 500 contacts; larger audiences require a paid marketing tier. See Billing for tiers and pricing. If your audience exceeds your plan’s contact limit, you cannot send new campaigns until you upgrade or remove contacts.
How a Campaign Moves Through Its Lifecycle
Every campaign goes through the same states from the moment you create it to the moment it’s sent and reporting.
Two things to know up front:
- Once a campaign enters Preparing, it cannot be cancelled. Only a
Scheduledcampaign can be moved back toDraft. - Once a campaign reaches Sent, its content is frozen. You cannot edit a sent campaign — duplicate it instead.
The Campaign Workflow
1. Create
Start from scratch, from a template, or duplicate an existing campaign
2. Build content
Design with the visual editor, write raw HTML, or use AI assistance
3. Choose your audience
Pick all contacts, specific lists, segments, or a combination
4. Send or schedule
Send now or pick a future date and time
5. Review results
Track opens, clicks, bounces, and unsubscribes
Quick Start
1
Open the Campaigns page
Click Campaigns in the sidebar. You’ll see a list of past and in-progress campaigns.
2
Create a new campaign
Click New campaign. You can describe what the campaign is about, and Lettr’s AI will pre-fill the subject and pull sender defaults from a similar previous campaign if one exists.
3
Walk through the builder
The campaign builder is a four-step wizard:
- Compose — subject, from address, content
- Audience — who receives it
- Schedule — send now or later
- Review — a final check before sending
4
Test before sending
From the builder you can send a test email to yourself or your team to check rendering and merge tags before committing to the full send.
5
Send or schedule
From the Review step, Send now dispatches immediately or Schedule picks a future time.
6
Watch the results
Open the campaign’s Show page to see live progress while it sends, and engagement metrics afterwards. Stats keep updating for the full window after the send.
Where Campaigns Live
Campaigns are authored in the Lettr dashboard. You build content, choose your audience, and review the send from the web app. If you need programmatic email sending for application events, use the transactional email API instead — the two systems serve different purposes and are intentionally separate.Next Steps
