# Email

While you will be using *WebEngage* to create all your *Email campaigns,* the actual delivery of the message to your target audience is facilitated by an *Email Service Provider (ESP)* like [Kenscio](http://google.com), [Mandrill](mandrill), [Netcore](netcore) and so on.

> 👍 We recommend integrating your Website or App with WebEngage to send real time personalization messages to your users

## ESP

You can think of *ESPs* as middle-men that transmit the message from *WebEngage* to your users' *mailbox provider (like Gmail, Yahoo! Mail, Microsoft Outlook).* We have partnered with several global ESP leaders to help make *Email marketing* a seamless process.

### ESP Integration

As shown below, you can integrate multiple *ESPs* with your project by navigating to the left side of the dashboard and clicking on *Data Platform* > *Integrations* > *Email Setup*.

Here, you will find a list of all the *ESPs* for which we provide ready-to-use integrations. If you have already added a few *ESPs* to your project, you will see configuration details in the upper half of this section. For example, in the visual below, you can see that two ESP have been integrated *[Sendgrid](https://docs.webengage.com/docs/sendgrid)*, *[Kenscio](https://docs.webengage.com/docs/kenscio)*, and *[Private ESP](https://docs.webengage.com/docs/private-esp)*.

As shown above, integrated ESPs are listed under the section, *Your Email Service Provider List.* You can choose to *[Edit](email#editing-an-esp)* or *[Delete](email#deleting-an-esp)* the integration anytime you like by accessing the *Actions* menu.

The *Actions* menu also allows you to add the *unique Webhook URL* to your *WSP dashboard* to ensure that *delivery status notifications ([sent, failed, queued, delivered](https://knowledgebase.webengage.com/docs/channel-campaign-performance-metrics#email))* are tracked under campaign stats in your WebEngage dashboard.

#### Editing an ESP

You can choose to edit configuration details in case incorrect details were entered during configuration or the ESP updated some details post-integration.

As shown below, you can make changes by selecting *Edit* from the *Actions* and clicking on *Save.*

#### Deleting an ESP

Deleting an integration will cease campaign delivery for all *[Running](https://knowledgebase.webengage.com/docs/campaigns#running)* and *[Upcoming](https://knowledgebase.webengage.com/docs/campaigns#upcoming)* campaigns where the respective ESP was selected for sending it. In such cases, you will be prompted by the following message.

To delete an ESP, kindly ensure that no existing campaigns are dependant on the intended ESP for sending Emails to your users.

As shown below, select *Delete* from the *Actions menu* and click the *Delete button* in the pop-up to confirm your decision.
