Frequently Asked Questions

Common questions about Lettermint

You can get your API token from the Lettermint Dashboard in your project settings.

Yes! The plugin seamlessly integrates with WordPress's wp_mail() function, so all plugins and themes that send emails will automatically use Lettermint.

The plugin automatically detects common email plugins and shows a warning if conflicts are detected. You should deactivate other email plugins to avoid conflicts.

Yes! The plugin includes a built-in test email feature in the Settings > Lettermint > Test Email tab.

No, logging is optional but recommended during setup to help troubleshoot any issues. You can disable it once everything is working properly.

Yes. Every setting can be supplied with a PHP constant or an environment variable instead of the settings screen, which keeps secrets and environment-specific values out of the database. See the Installation section for the available names.

Yes. The plugin adds a wp lettermint command for sending test emails, checking your token, and viewing, pruning, and summarising logs. See the Installation section for the full command list.

Yes. Lettermint is designed for repeatable, scripted setup. Because every setting can be supplied as a PHP constant, you can configure a site entirely from the command line, with no dashboard steps, and keep the API token out of the database: wp plugin install lettermint --activate wp config set LETTERMINT_API_TOKEN lm_your_token --type=constant wp config set LETTERMINT_FROM_EMAIL hello@example.com --type=constant wp config set LETTERMINT_FORCE_EMAIL 1 --type=constant Then confirm everything works: wp lettermint status wp lettermint test you@example.com Since the configuration lives in wp-config or environment variables, you can bake these steps into a provisioning script, deployment pipeline, or site template and roll out identical email settings across every client site. See the Installation section for the full list of constants and wp lettermint commands.
