The campaign builder is a guided, four-step wizard that takes you from an empty campaign to ready-to-send. This page covers each step at a high level. Deeper details about the content editor, audience picker, and scheduling controls live on their own pages.

​

Starting a New Campaign

There are three ways to start a campaign:

​

From Scratch

Click New campaign on the Campaigns page. You’ll see a prompt asking what the campaign is about. You can fill in a short description — this becomes a starting point for the campaign name and, if you fill it in, lets Lettr’s AI generate a suggested subject line and pull sender defaults from a similar campaign you’ve sent before. You can skip the prompt and fill in everything by hand if you prefer.

​

From a Template

You can also link the campaign to an existing template from the Compose step (see below). Linked campaigns inherit the template’s HTML and stay in sync with it while they’re in Draft — see Content & Design for details.

​

Duplicate

From the Campaigns list, choose Duplicate on any campaign. A new Draft is created with the same subject, sender, content, and audience configuration. Modify whatever you need and send it as a new campaign — the original is unaffected. You can also duplicate multiple campaigns at once from the bulk action bar on the Campaigns page.

​

The Four-Step Builder

Once you’ve created a campaign, you land in the builder. It’s organized as four steps you can move through in order, but you’re free to jump back and forth — Lettr saves your progress automatically as you edit.

​

Step 1 — Compose

The Compose step is where you set the email itself:

• Subject line — what recipients see in their inbox. Lettr offers an AI spam check that highlights words and patterns that might trigger spam filters.
• From address — choose the local part (the bit before the @) and pick which of your verified sending domains to send from.
• From name — the display name recipients see (for example, “Acme Newsletter” instead of just the email address).
• Reply-to — optional. An address recipients reach if they hit “Reply”.
• Content — the body of the email. You can use the visual editor, the HTML editor, or link to a template.

See Content & Design for the full editor experience.

​

Step 2 — Audience

The Audience step is where you choose who receives the campaign. You have three options:

• All contacts — every subscribed contact in your audience
• Lists — one or more audience lists
• Segments — one or more segments

The builder shows you an estimated recipient count next to each option as you pick. The estimate filters down to only subscribed contacts and deduplicates across overlapping lists or segments. See Audience Selection for how multiple selections combine and which contacts are filtered out.

​

Step 3 — Schedule

Decide when the campaign goes out:

• Send now — the campaign begins delivering as soon as you confirm
• Schedule — pick a future date and time. Until that moment, the campaign is in Scheduled status and you can unschedule it back to Draft at any point

See Sending & Scheduling for timezone behavior and the full schedule mechanics.

​

Step 4 — Review

The Review step shows a summary of everything you’ve set up: subject, sender, audience size, schedule, and a preview of the email. From here you can:

• Send a test email to yourself or a colleague to check rendering and merge tags
• Go back to any prior step to make adjustments
• Send (or Schedule) to commit the campaign

​

Saving Progress

Edits in the builder save automatically as you make them. You can close the page and come back later — the campaign stays in Draft status until you explicitly send or schedule it.

​

Deleting a Draft

If you decide not to send a campaign, you can delete it from the Campaigns list. Deleting is only allowed for Draft and Failed campaigns — once a campaign has been scheduled, prepared, or sent, deletion is disabled (you can unschedule a Scheduled campaign back to Draft if you want to delete it).

​

Test Emails

The Send test email button in the builder sends a single copy of the current campaign to one or more recipients you specify. Tests are sent as transactional emails — tracking is disabled on test sends — and they’re rate-limited to prevent accidental flooding. Test emails are a good way to:

• Check how the campaign renders in different mail clients
• Verify that merge tags resolve correctly (test emails use whatever recipient you specify, so unique-to-recipient merge tags will look different in a real send)
• Run the campaign past stakeholders for approval before launch
