# Build contact lists and add subscribers

## Steps

1. Go to **Marketing → Email**.
2. Under **contact groups/lists**, click **Add group** and name it (e.g. "Newsletter").
3. Add subscribers by entering them, or **import** a list. Consent is tracked per contact to help you stay CASL-compliant.
4. Use groups to target campaigns to the right audience.

## Good to know

- Only email people who have consented. Every campaign includes an unsubscribe link and your sender info automatically.
- Signup **forms** can add new subscribers to a group automatically (see *Build a form and embed it*).

## Troubleshooting

- **Import rejected** — check your file's format and that emails are valid.
- **Low deliverability** — send only to consented, engaged contacts; remove hard bounces.
