The dashboard
A tour of the mailer123 web app — how to get set up and where every feature lives.
These guides cover the web app — creating and sending email from the dashboard, no code required. (For the REST API, see the API reference; to drive everything from an AI assistant, see MCP.)
Getting set up
The first time you sign in, an onboarding wizard walks you through two things:
- Create a project. A project (workspace) holds its own contacts, domains, templates, and campaigns. Everyone you invite to a project shares its data.
- Add a sending domain. You can't send until at least one domain is verified — see Domains for the DNS steps.
Once a domain is verified you land on the Dashboard, which shows your last 30 days of sending — emails sent, delivered, opens, clicks, bounces, complaints — plus quick counts of contacts, groups, and campaigns, and any campaigns that are currently sending.
Where things live
The left sidebar is the map of the app:
| Section | What it's for |
|---|---|
| Dashboard | At-a-glance activity and engagement for the last 30 days. |
| Contacts | Your audience — people, custom fields, and groups. See Contacts. |
| Templates | Reusable email bodies. See Templates. |
| Campaigns | Create, send, schedule, and track bulk email. See Campaigns. |
| All Mail | A searchable log of every individual email and its events. See Sending email. |
| Domains | Add and verify sending domains; watch their reputation. See Domains. |
| API | Create and manage API keys (project owners only). See Authentication. |
| Metrics | Time-series delivery and engagement charts. See Analytics. |
| Suppressions | Addresses that won't be emailed (bounced, complained, manual). |
| Unsubscribe page | The unsubscribe page designs appended to your emails. |
| Settings | Plan & usage, project members and invites, and your profile. |
A typical first campaign
- Verify a domain so you have a sender address (Domains).
- Add contacts — import a CSV or add them one by one (Contacts).
- (Optional) Save a template you can reuse (Templates).
- Create a campaign, pick your audience, write the email, and send a test (Campaigns).
- Send or schedule it, then track results in the campaign and Metrics.
Limits are shared across all the projects you own and reset daily and monthly — keep an eye on Settings → Usage. See Send quotas.
