# Welcome Emails

| Understanding how Welcome emails work. 

Welcome emails are emails used for Onboarding, Welcome series or Drip campaigns.

To get started, use ` Menu/Flows/Welcome`

This will generate a boilerplate campaign that you can modify. 

It's the same as a regular campaign with 2 important differences: rules for selecting contacts and the scheduler option.

In this example, we want to send a welcome email to contacts created today.

|| Rules for Selecting contacts.

The key to selecting contacts that match today’s date lies in comparing the `Contact createdon date` to today's date.  We use the `Diff in Days` function to find this value.  So a difference of 0 is today, 1 is yesterday and so on.

Segment rules for Recurring campaigns are evaluated just before the emails are sent. 

|| Scheduler option.

Set the schedule using red schedule icon on the Broadcast:

The most common option is to set the schedule to run `everyday` to accomodate your Diff in Days setting.  In other words, when this runs, it is looking for contacts that were created today, a day difference of zero.
