# Các Thay đổi trong Chuỗi Email Sequence Ảnh hưởng Thế nào Đến Học viên?

> Learn how editing an active Chuỗi Email Sequence Tự động affects existing and future subscribers differently.

Changes to an existing, active **Chuỗi Email Sequence Tự động** (one with current subscribers) impact subscribers differently depending on when they subscribed.

{% hint style="info" %}
**Tip:** Set up and finalize your Chuỗi Email Sequence Tự động before adding subscribers to ensure that the emails in your sequence are sent to all your sequence subscribers exactly as you intend.
{% endhint %}

## Existing subscribers

Existing subscribers already subscribed to your Chuỗi Email Sequence Tự động will only receive changes to **existing emails** in your sequence if they have not yet reached the sending day of the updated email.

\*\*Important:\*\* Emails added to a sequence cannot be sent retroactively to existing subscribers.

For example, if you created an Chuỗi Email Sequence Tự động with three emails sent on days 3, 5, and 7, and you later decided to add an email to be sent on day 6 of the sequence, that email will only be sent to subscribers who have not yet passed day 6.

## Người nhận tin (Subscribers) added after changes

Người nhận tin (Subscribers) added after changes to your Chuỗi Email Sequence Tự động will receive updates/changes to your Chuỗi Email Sequence Tự động moving forward:

* [Added email to the sequence](https://help.hifunnel.com/hc/en-us/articles/360037477793)
* [Edited existing email](https://github.com/hifunnel-org/hifunnel-help-center/tree/main/articles/marketing/email-campaigns/create-an-email-sequence/README.md)
* [Updated email settings in the sequence](https://github.com/hifunnel-org/hifunnel-help-center/tree/main/articles/marketing/email-campaigns/how-to-edit-your-email-sequence-settings/README.md)

We recommend setting up your Chuỗi Email Sequence Tự động before adding subscribers to ensure that any changes you wish to make are finalized for all subscribers in your sequence.
