The Dashboard is the first thing you see after signing in to Lettr. It serves as a real-time command center for your email operations — showing how many emails you’ve sent, whether your domains are healthy, and if anything needs your attention. The dashboard follows the mode you’re working in. In Transactional mode it focuses on API-driven sending; in Marketing mode (available when your team uses Audience or Campaigns) the same cards switch to campaign and contact metrics. Switching modes in the sidebar switches the dashboard with it.

​
Email Usage

At the top of the dashboard you’ll find your current usage for the billing period. In Transactional mode this shows the emails sent this month against your monthly quota, plus today’s sends against the daily limit where one applies. In Marketing mode it shows your contact count against your plan’s contact limit instead. Usage data is real-time — each email is reflected the moment it’s accepted for delivery, so you’re always looking at current numbers rather than stale data. For more details about how usage tracking works, quota enforcement, and what happens when you approach your limit, see Email Usage & Quotas.

​
Email Traffic

The traffic section displays a 30-day chart of your email sending volume, broken down by day. The chart is mode-aware: in Transactional mode it shows your API and SMTP sending with campaign volume excluded, so campaign blasts don’t drown out your transactional baseline; in Marketing mode it shows campaign sends as bars on their send dates. If you notice an unexpected drop or spike, the traffic chart is often the first place that surfaces it.

​
Delivery Performance

Below the traffic chart, key delivery metrics give you a snapshot of how your emails are performing over the trailing 30-day period: In Marketing mode, the delivery metrics additionally include click and unsubscribe rates. These numbers update approximately every 15 minutes. For deeper analysis — including breakdowns by domain, time period, and engagement type — the Analytics section provides more detailed reporting tools.

​
Analytics by Tag and by Campaign

The dashboard includes a 30-day analytics table that groups sending stats by tag in Transactional mode and by campaign in Marketing mode. Campaign sends are excluded from the tag table — they belong to campaign analytics — and transactional emails sent without a tag are grouped in an Untagged row so nothing disappears from view.

​
Domain Health

The dashboard surfaces the verification status of your sending domains so you can spot DNS configuration issues without navigating to the Domains section. For each domain, you’ll see whether the DKIM, CNAME, and DMARC records are valid, unverified, or missing. Domains with issues are highlighted, making it easy to identify which ones need attention and click through to resolve them.

​
Alerts

When something in your account needs attention, the dashboard generates alerts. These are designed to surface problems before they affect your sending: Usage alerts follow the mode you’re viewing — email quota in Transactional mode, contact limit in Marketing mode — while domain alerts are shared across both. Critical alerts indicate issues that are actively preventing you from sending or are about to. Warning alerts give you advance notice so you can take action before things become urgent.
New accounts are guided through the essential setup steps — adding and verifying a sending domain, creating an API key, and sending a first email — by Adamko’s onboarding flow. See Onboarding for the full walkthrough.
