What LetterPress does
LetterPress covers the four kinds of email a WordPress site usually needs:
| Area | What you get |
|---|---|
| Unified email design | Every email WordPress sends: password resets, WooCommerce orders, form submissions, appointment confirmations. All go out in one consistent, on-brand template. Set it once, and every touchpoint looks like it came from the same team. |
| Email design | A drag-and-drop builder for professional emails, no HTML required |
| Email marketing | Subscribers, groups, campaigns, scheduling, and reports |
| Email delivery | SMTP and provider integrations so email actually reaches the inbox |
LetterPress Pro adds AI email generation and ready-made integrations for WooCommerce, forms, memberships, and LMS plugins. See LetterPress Pro.
Requirements
Before you install, make sure your server meets the following minimums.
| Requirement | Minimum | Notes |
|---|---|---|
| WordPress | 6.5 or newer | Tested up to WordPress 7.1 |
| PHP | 7.4 or newer | PHP 8.x recommended for best performance |
| MySQL / MariaDB | 5.7 / 10.3 or newer | Standard WordPress database requirement |
| HTTPS | Strongly recommended | Required for Amazon SES SNS event webhooks |
| A sending provider | At least one | SMTP credentials or a supported API provider (Amazon SES, SendGrid, Mailjet, Mailgun, Postmark, Brevo, Resend, SparkPost, MailerSend, Mandrill, SMTP2GO, ZeptoMail) |
LetterPress works with WordPress's built-in wp_mail() out of the box, but connecting a dedicated sending provider dramatically improves deliverability. See Email Delivery to get started.

The LetterPress menu

The one minute tour
The fastest way to learn the plugin is a lap around its main screens. This short tour walks through the dashboard, campaigns, templates, subscribers, groups, sources, and settings.

Recommended first steps
- Set up delivery. Open Settings > Email providers and connect your sending provider or SMTP credentials. This is the most important step, because WordPress default emails route through the same setup. See Email Delivery.
- Set your sender identity. Under Settings > Sender identity, add the From name and From address your email will use.
- Design a template. Open Templates and build your first email with the builder. See Email Builder.
- Add subscribers. Import a CSV or connect a signup form. See Subscribers.
- Send a test campaign. Create a campaign, send yourself a test, then schedule or send it. See Campaigns.
