# Best Sendout Channel in Mapp Engage

## What is Best Sendout Channel?

Best Sendout Channel is a pre-calculated statistic that allows you to create intelligent segments, based on which channel is most used by the contact: Email, Push or InApp. The statistic is currently unavailable for SMS.

## How is Best Sendout Channel calculated?

Each message provides engagement information, depending on channel and which interaction options are chosen by the user.

Best Sendout Channel considers two parameters:

- contact's interactions (events) with messages from different channels: read, click, dismiss, delete, etc., and
- read percentage, which is the the ratio between messages read by the user, and all sent messages.

## Which interactions (events) translate into contact engagement?

The table below shows which engagement status is produced by the contact's interactions with messages from different channels. The engagement status provides a weight for each data point: **Low** = **1**, **Medium** = **2**, **High** = **3**.

| Channel | Events | Engagement Status |
| --- | --- | --- |
| Email | read | Low |
| read and click | High |
| In-App | iaMessageDismissal | Low |
| iaMessageCustomAction | High |
| iaMessageDeepLink | High |
| iaMessageLandingPageInternal | High |
| iaMessageLandingPageExternal | High |
| iaMessageAppStore | High |
| In-App - inbox | inboxMessageDeleted | Low |
| inboxMessageCustomAction | High |
| inboxMessageDeepLink | High |
| inboxMessageLandingPageInternal | High |
| inboxMessageLandingPageExternal | High |
| inboxMessageAppStore | High |
| Push | dismiss | Low |
| open | Medium |
| click | High |

## How does read percentage affect the weight of the data point?

The following table show events used to calculate this parameter.

| Channel | Send Events | Read Events |
| --- | --- | --- |
| Email | sendout | read |
| In-App | iaMessagesDisplayediaMessagesNotDisplayed | iaMessagesDisplayedinboxMessagesRead |
| In-App - inbox | inboxMessagesRead inboxMessagesUnread |
| Push | delivery | dismiss, open, click |

## Example 1

You send 100 Email messages and and 10 Push messages to your contact.

1. The contact reads 10 emails and dismisses 10 push messages.
2. Considering that both read and dismiss provide a low engagement (and each event is one data point), the algorithm calculates that **Email** has a read percentage of 0.1 (10%) while **Push** has 1 (100%).
3. The number of data points multiplied by the read percentage is 10 * 0.1 = 1 for **Email** and 10 * 1 = 10 for **Push**.
4. The best channel is **Push**.

## Example 2

You send send 100 Email messages and and 1 Push message to your contact.

1. The contact reads 10 emails and dismisses 1 push message.
2. **Email** has a read percentage of 0.1 (10%) while **Push** has 1 (100%).
3. The number of data points multiplied by the read percentage is 10 * 0.1 = 1 for **Email** and 1 * 1 = 1 for **Push**.
4. Both have the same score, but since the number of read emails (10) is higher then the number of dismissed push messages (1) the best channel is **Email**.
