How to create a system mailing list
Table of Contents
System-based messaging allows you to send out a newsletter via a bot that accepts subscribers into a channel after the user performs one of the following actions: Subscribing to a channel, Unsubscribing from a channel, Registering for your product, Selling, or Reselling .
The newsletter is sent after the action is performed at the time you specified. If "Send only once" is not checked, the newsletter will be re-delivered to the user each time they unsubscribe and then subscribe to the channel.
Let's take a closer look at the form for adding a system mailing list:

Name
The name of the newsletter is for your convenience.
Mailing type
Select the “System” mailing type
Event
Select the event after which you want to send a message.
Date and time
Select the time after the user completes the selected action to send the message. If you specify 00:05, the message will arrive in 5 minutes.
Spot
Specify the spot(s) to which the mailing should be sent.
Editing rights
Select employees who can edit this newsletter.
Send only once - the newsletter will be delivered to the user only once, regardless of the number of subscriptions and unsubscriptions from the channel.
Rights of deletion
Select employees who can delete this mailing list.
Text
Enter the text of the message to be sent. Available macros:
{name} - username
{link} - the offer link specified in the Spot , in the Deals tab. This macro is useful if you want to insert an offer link, but your campaign includes multiple spots and each has a different link (⚡️Note: the macro name must match the name you specified in the Deals tab).
{manager} - manager link. This macro is useful if you want to insert a manager link, but your mailing involves multiple spots and each has a different link. The link will be taken from the Communication Channel field in the Spot settings.
{channel_link} - the channel link specified in the Spot. This macro is useful if you want to insert a channel link, but your campaign involves multiple Spots and each has a different link.
Click the "Add" button and you're done! Users will receive the newsletter at the specified time.
*We recommend creating newsletters at least 5 minutes before sending.
