# Why aren't my contacts entering a sequence?

> A sequence starts only for new matches, and CSV imports leave Enroll in sequences off by default. Enroll the existing contacts from the sequence or the Contacts page.

A sequence starts for contacts who match its trigger **after** it is
activated. Contacts who already had the tag or were already on the list are
not picked up, and contacts added by a CSV import are not enrolled unless you
switch that on. Enroll them yourself in a few clicks.

## Find the cause

| What you see | Cause |
| - | - |
| The contact page shows **Not enrolled in matching sequences** | The contact was added with enrollment off, by an import or an API call. |
| You imported a file and nobody entered | **Enroll in sequences** is off by default on the import page. |
| You imported the same file a second time and nothing changed | **Duplicate handling** was **Skip**, so existing contacts were left untouched. |
| The contacts had the tag or list before the sequence was turned on | Sequences do not go back for earlier matches. |
| Nobody enters at all | The sequence is not active, or the trigger does not match what the contacts have. |
| One contact is missing | The contact is unsubscribed or bounced, so they are not emailed. |

## Enroll contacts who already match

Open the sequence and click the **Sequence subscribers** button in the header,
then the **Enroll** tab. Choose the contacts and confirm. See
[Enroll Existing Subscribers](https://docs.sequenzy.com/concepts/enroll-existing-subscribers.md).

## Enroll specific contacts

On the Contacts page, select the contacts and choose **Enroll in sequence**.
They start at the first step of the sequence you pick.

To start someone part of the way through, open the step's menu in the sequence
and choose **Enroll subscribers here**. They skip every earlier step.

## For future imports and API calls

* On the import page, turn on **Enroll in sequences** before you import.
* In API calls that create a subscriber, leave `enrollInSequences` at its
  default of `true`. A form or integration that sends `false` creates the
  contact without starting any sequence.

## Without the dashboard

```bash CLI theme={null}
sequenzy sequences enroll seq_abc123 --email one@example.com two@example.com
sequenzy sequences enroll-audience seq_abc123 --segment-id seg_past_buyers
```

```text MCP theme={null}
enroll_subscribers_in_sequence
enroll_sequence_audience
```
